Eco-Friendly Building Cleaning Chemicals

Our softwash trolley enables you to complete more work in a day by utilising a high-quality lithium battery for 50% less battery weight and fast charging via digital charger which means you are independent of external power sources for up to 12 hours.

This is a true portable softwash system complete with Viton seals on the pump to handle the harshest of chemical like sodium hypochlorite or Algoclear and the like.

Softwash Trolley

The robust folding powder-coated handle and frame of the trolley means it is easy to store while being transported and we offer a 50-litre version as well – the pump’s flow rate is around 3.8 litres per minute and the system comes with a short hose and application wand. The digital pump controller built into our softwash trolley gives you better control over flow-rates and up to the minute information on battery charge status.

The trolley costs £1450.00 + VAT and carriage – you can buy it online by clicking the link on the button below:

Having Viton seals in the chemical resistant pump means that the softwash trolley can be used with several popular biocide chemicals like SmartSeal, AlgoClear or with sodium hypochlorite solution as used with some applications of render or cladding cleaning reliably with this trolley.

A more up-to-date solution however is to use our eco-friendly aqueous cleaning solution called RenderKleen or BuildKleen. This is an entirely environmentally friendly and odourless detergent cleaner that uses advanced formulation to break the bonds of algae and dirt to dislodge and remove the soiling rather than killing it.

This unique breakthrough British-made product comes at ready-to-use strength in 20-litre jerrycans and is both food-safe and with harmless runoff in drains or a water course.

BuildKleen is an effective and highly innovative mortar and brick cleaner chemical that is very safe and contains no acids; have you heard of a brick cleaner that is food-safe before?! The product is non-hazardous, non-toxic, and certified as food safe and needs no PPE when in normal use which is a refreshing change from hydrochloric acid and the safety risks it can bring while still highly effective.

Mortar And Brick Cleaner

If you are looking for an environmentally friendly and non-corrosive cleaner, then this is a great mortar and brick cleaner for you. You can apply with a low-pressure sprayer, sponge, roller or brush and scrub thoroughly and leave for five minutes or so for the cleaning to take place; often needs more than one application.

A pressure washer – used carefully – can also help with stubborn or very old dirt and with removing the loose dirt after application, however, a garden hose can also help a good deal as rinsing is important.

How Does It Work?

Using nano-technology energy packages this cleaning chemical penetrates deeply and dislodges algae, dirt and stains off mortar and brickwork by breaking the surface tension and lifting off the dirt – thus our expression ‘Cleans Not Kills’ because unlike biocides it does not kill anything and is pH neutral as well.

These nano-energy packages could be thought of as being like piranhas in the Amazon that are just milling around and waiting to attack and tear dirt away like piranhas would feed by tearing meat off the bones of their prey. A surface treated with this mortar and brick cleaner stays algae-free for longer and in our tests, natural stone absorbs rainwater in a more natural way that is almost like ‘breathing’.

BuildKleen is a pH-neutral masonry cleaner that contains:

No biocides or bleach.
No strong acids or alkalis.
Certified as food-safe
No odours

Eco-friendly brick cleaners are becoming more common and BuildKleen is a good value example of this trend. It is effective as a limestone and sandstone masonry cleaner of dirt and algae as it is pH neutral. The perfect cleaner for stonework and stone statues on heritage or listed buildings with a combination of aggressive action while gentle and safe to handle and as run-off and ultra-safe food-grade safety for cleaning staff.

The product is supplied in 5-litre containers and 20-litre jerrycans as shown above and is at ready-to-use dilution for maximum convenience. To see the power and effectiveness of BuildKleen please let us know if you would like a sample by email at info@acute.uk.com.

You will find council clients are delighted to hear of the steps you are taking to lower any chemical risks for masonry cleaning – for example near children’s play areas and it may help you win more tenders that you quote on for masonry cleaning.

Mortar And Brick Cleaner

More and more firms are looking for cleaning contractors that demonstrate care for the environment and this eco-friendly mortar and brick cleaner is a cost-effective option for you to do just that.

It is important also to rinse the area that you have treated so that ingrained dirt is carried away and this can be done with a pressure washer or a garden hose.

BuildKleen can be sprayed effectively but please ensure a generous quantity is in contact with the concrete that is to be cleaned and that this is both brushed in and rinsed off with a generous quantity of water.

Cement Floor Cleaner

Cleaning rendered walls can make a dramatic difference to the appearance of a building. Whether it is a dwelling or school, has coloured or painted render, pebble dash or roughcasting, the walls will tend to suffer in our damp climate or may have a whisky storage bond nearby that makes walls and window sills go black.

Cleaning Rendered Walls

Green algae and just general weathering and atmospheric pollution are other factors to consider that can turn beautiful light shades and colours of render black or green and unsightly.

The traditional answer is generally applying a biocide-based chemical to kill the spores and algae on the render – often marketed as ‘softwashing’ – and involving sodium hypochlorite and then leaving the weather to wash off the dead algae.

Our Answer – RenderKleen

RenderKleen is an innovative chemical for cleaning rendered walls that works very differently to the traditional process described above. It is a non-toxic and non-hazardous aqueous cleaning solution that uses millions of nano-energy packages in the mix to penetrate under the soiling and algae to dislodge it and loosen it off.

The contrast to the killing action described above is the revolutionary factor in why the cleaner is so safe to use and superior to many existing treatments. Biocides are disinfectants and while ‘hypo’ as it is called, is effective, it smells awful, the fall out kills plant life, ruins clothes, and who know what it does to you?!

Using RenderKleen means much quicker cleaning action and – importantly – that the process is very safe as the RenderKleen chemical is food safe as tested by Campden BRI labs and thus safe for operators and pets, lawns and even for aquatic life.

It Is Really That Safe?

Yes, it is – workers using RenderKleen for cleaning rendered walls do not even need PPE, there are no hazard warning pictograms on the packaging and the product is delivered to the site in 5 litres or 20 litres jerrycans at ready-to-use strength for convenience.

A situation that could have been tragic with any other chemical arose recently where a contractor used a rubber tube and his mouth to try and siphon the chemical from 20-litre jerrycan into smaller bottles and got a mouthful – in his surprise he swallowed it – and, apart from a funny taste, was fine!

Cleaning Rendered Walls

How Is Best To Apply It?

This odourless cleaner solution is used in cleaning rendered walls by spraying on generously and several times or brushing or rolling on and then agitating with a semi-stiff broom or brush to help dislodge soiling, you will note a light foaming that colours with the debris.

After this leave for 5 to 10 minutes, wash off, and reapply by sprayer – we always suggest that you try a test patch first. The product is ideal as a painted render cleaner but please be aware that if the paint is in a bad state, it can easily remove some in the same way it will give algae short shrift.

Can I Use A Pressure Washer?

Yes you can – the key point is to use the pressure washer on fan setting and gently so as not to damage the render and not bring the nozzle of the lance to close and concentrate too long on a small part of the render.

Cleaning rendered walls using a pressure washer in combination with our RenderKleen chemical makes a lot of sense as it helps penetration and, as RenderKleen can often liberate A LOT of soiling, you want to wash this away rather than letting some of it dry in situ.

RenderKleen 20 Litre – £80.00 + VAT Each

Keeping gutters and pvc downpipes looking presentable is challenging in our damp British climate with ideal conditions for algae, moss, and lichens to grow and thrive. This calls for a gutter cleaning chemical that cleans in an environmentally friendly way without too much hard work and reduces re-infestation.

BuildKleen is just such a ready-to-use aqueous cleaning solution with industry-leading safety and effective cleaning performance for facilities managers and maintenance companies.

Gutter Cleaning Chemical

How Does It Work?

The process of cleaning gutters and uPVC fascia is by getting underneath the algae and dirt and loosening and dislodging it for rinsing off instead of killing the algae as is the case with biocide-based cleaners. Most brands of outside cleaning chemicals and fascia cleaning products use biocides – disinfectants – to kill the green growth whereas ours uses none.

Gutter Cleaning Chemical

In some cases, the biocide-based chemicals are biodegradable but toxic to aquatic life and in some cases to pets and carry hazard warning pictograms about how they can damage your skin. If you are concerned about the environmental impact of your activities, you’ll think twice before you use them on your gutters.

Our gutter cleaning chemical is:

Certified as food safe by Campden BRI, no danger to you or to pets or lawns.
Non-toxic and non-hazardous – contains no caustic acids.
Contains no biocides or disinfectants – no danger to plants or lawns nearby.
Contains no bleach or sodium hypochlorite.
Slows regrowth of algae.
Made in the UK.
Needs minimal or no PPE.

Gutter Cleaning Chemical

BuildKleen cleaner is stable, effective, safe, and environmentally friendly and biodegradable and is supplied in 5 litre or 20 litre jerrycans at ready-to-use dilution. Use of a power washer or garden hose is normally helpful in the cleaning process and disperses the dirt better after cleaning.

Buy BuildKleen at ready-to-use strength here.

Application can be by a low-pressure sprayer (as used for weed killer) or a watering can, sponge, paint roller or poured on. Agitate the solution with a stiff brush and leave for at least half an hour before rinsing off.

Non-corrosive, non-acidic, non-toxic, and non-hazardous, this gutter cleaner chemical is even certified as food safe, and is safe to use near a water course.

BuildKleen is the eco-friendly fascia cleaner chemical in our range of chemicals and fascia cleaning products that is perfect for soffit cleaning. It is ideal for quick and safe cleaning of all fascia and soffits and finishing off cleaning guttering that has suffered dirt and algae growth. This cleaning takes place in an environmentally friendly and safe manner that protects you, pets and plants.

Fascia Cleaner

This non-toxic and non-hazardous fascia cleaner chemical is something of a first as its cleaning action is not biocide or disinfectant-based; it is a great addition to our fascia cleaning products range.

It is delivered in 5 litre or 20 litre containers and operators using it do not need any PPE. Nearly odourless, pH neutral, and with no acids, no caustic alkalis, no biocides, no bleach, or sodium hypochlorite. BuildKleen is perfect as a soffit and fascia cleaner, roof, or cladding cleaner chemical at ready-to-use dilution; surfaces treated with it tend to resist fresh build-up of algae and soiling because the surface is left very clean.

How Does It Work?

BuildKleen works by using nano-size energy packages which break the surface tension between dirt and the substrate to lift off the soiling from fascia and soffits.

Many outdoor cleaning products rely on sodium hypochlorite, DDAC, or biocides to kill the green growth which means considerable precautions are needed and runoff can be dangerous, especially in aquatic environments.

Fascia Cleaner Products

By using a unique formulation, we can offer an all-natural and very safe soffit and fascia cleaner product that is powerful and indeed is even safe if it gets into a water course. With many cleaning agents, the large particles are removed from the substrate, but smaller ones are left. Because of the penetration of the nano energy particles in BuildKleen, this cleaner liberates much more soiling and thus leaves a super-clean surface.

Careful use of a pressure washer on low pressure can be helpful to remove loosened dirt and algae or just a garden hose. Remove as much moss as possible if present and apply the solution with a brush, or from a sprayer, saturate the surface well and then agitate with a brush or sponge.

On cladding spraying works well and the cleaning benefits from more than one coat, ideally wait 10 minutes before rinsing off the dirt and soiling. Please watch our simple video about a long-reach flat surface cleaner tool video. You can buy this detergent product online here.

RoofKleen is the eco-friendly roof tile cleaner chemical in our range of building cleaning chemicals. It is ideal for cleaning slate, clay and concrete tiles that have had moss scraped off in an environmentally friendly and safe manner that protects personnel, pets and plants. This non-toxic and non-hazardous detergent is something of a first as its cleaning action is not biocide or disinfectant-based.

Roof Tile Cleaner

Available in 20-litre jerrycans and delivered all over the UK, persons using the product do not need any PPE and it is nearly odourless, pH neutral, with no acids, no caustic alkalis, no biocides, no bleach, or sodium hypochlorite solution.

RoofKleen is delivered at ready-to-use dilution but if the job you are on does not have heavy soiling you can water it down as well. Another great feature of RoofKleen is that surfaces treated with it tend to resist fresh build-up of algae and soiling because the surface is left very clean.

How Does It Work?

This food-safe roof cleaner chemical works by using nano energy to break the surface tension between dirt and the substrate to lift off the soiling from tiles, fascia and soffits. The majority of chemicals rely on sodium hypochlorite or biocides to kill the green growth on a roof which means considerable precautions are needed, smells are very strong, and runoff can be dangerous.

By contrast, RoofKleen is almost odourless and this innovative approach to cleaning offers a genuinely all-natural and powerful solution whichis even safe if it gets into a water course during use.

How To Use RoofKleen

Careful use of a pressure washer can be helpful to remove loosened dirt and algae or just a garden hose or similar. Remove as much moss as possible by scraping and apply the detergent by pouring, with a brush, or from a sprayer, saturate the surface well and then agitate with a brush.

On cladding spraying works well and the cleaning benefits from more than one coat, ideally wait 5 minutes before rinsing off the dirt. A second application may be needed and a long-reach rotary cleaner is a very useful tool for cleaning roof tiles, you can see our one on this link.

Roof Tile Cleaner

A top performing painted render cleaner, RenderKleen chemical goes into action and transforms your building by dislodging algae and dirt on masonry painted walls.

Painted Render Cleaner

An aqueous cleaning solution, this ultra-safe and ready to use eco-friendly render cleaner is available in 5 litre or 20 litre containers. RenderKleen is becoming more common in the trade as people prove the benefits of safety for staff, no smell, quick action and run off that is harmless to the environment, lawns, water courses or pets.

Why Painted Render?

The nano-energy dislodging action – as explained below – means that RenderKleen is a somewhat ‘penetrating’ cleaner so that under some circumstances on very dirty un-painted render, harling, roughcast or pebbledash it can soak in and bring old dirt to the surface.

With a masonry-painted render or rough casting however it is a less porous surface, and the cleaner will be stopped by the paint and then safely strips the dirt off a semi-sealed surface making it one of the best painted render cleaners that are available.

How Does It Work?

Different from most conventional cleaning chemicals, RenderKleen utilises nano-energy packages within the agent that penetrate and dislodge the algae and dirt leaving a clean painted render surface that also lasts for longer than when treated with sodium hypochlorite.

These nano-energy packages are like piranhas just milling around and waiting to attack and tear dirt away like piranhas would feed by tearing meat off the bones of their prey.

Painted Render Cleaner

Safety With Results

Non-hazardous, non-toxic with zero biocides, acids, or bleach and certified food-safe, this is one of the best-value render cleaners out there and is more sustainable and superior in results to cleaning render with bleach.
