Buy our eco-friendly patio slabs cleaner chemical online here to help with pre-washing your patio slabs and removing algae and dirt, grime, and staining.

Patio Slabs Cleaner

Our carefully developed PatioKleen product is an aqueous cleaning solution that is non-toxic and non-hazardous and yet provides remarkably effective and powerful cleaning action on concrete slabs and natural stone patios and driveways.

PatioKleen works differently to many chemical products used in the exterior cleaning trade as it does not work by using biocides to kill algae but instead works to get underneath and dislodge the dirt and algae by breaking the surface tension using millions of nano-energy packages in the mix. There are no acids, no biocides, no bleach, and no sodium hypochlorite in this patio slabs cleaner; it is both stable and uniquely safe to use and handle.

A pressure washer used carefully with a rotary patio cleaner attachment and hood helps with removing stubborn dirt and to wash away loose dirt after application.

PatioKleen is actually a food-grade cleaner for which users do not need even need PPE and there are no hazard pictograms on the packaging. It is fast-acting, easy to use, safe for use near lawns and pets and is perhaps the only patio slabs cleaner that is even safe if spilled into a water course!

Because the chemical is pH neutral it is great for cleaning natural stone like granite and slate and is delivered to you at ready-to-use dilution for convenience so you can use it straight away.

Patio Slabs 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 basically 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 site in 5 litres or 20 litres jerrycans at ready-to-use strength for convenience.

Download our k rend algae clean product SDS data sheet here.

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 dislodging 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 do 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 obviously want to wash this away rather than letting some of it dry in-situ.

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’s 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 – basically 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 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 in 5 litre and 20 litre 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 have 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’s and soffits. The majority of exterior cleaning chemicals rely on sodium hypochlorite (bleach) or biocides to kill the green growth which means considerable precautions are needed and run off 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 in to 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 nanoenergy 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 quarter of an hour to an hour before rinsing off the dirt. Please watch our simple guide video on how to apply cleaner. And you can buy the product online here.

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.

Roof Tile Cleaner

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 cleaning solution works by using nano-size energy packages which break the surface tension between dirt and the substrate to lift off the soiling from tiles, fascia’s and soffits. The majority of roof tile cleaner chemicals rely on sodium hypochlorite (bleach) or biocides to kill the green growth which means considerable precautions are needed and run off can be dangerous.

This innovative approach to cleaning is a UK invention and the product is made in the UK. By using this unique formulation, we can offer a genuinely all-natural and very safe roof tile cleaner that is powerful and indeed is even safe if it gets in to 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 nanoenergy particles in RoofKleen, this cleaner liberates much more soiling and thus leaves a super-clean surface.

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 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.
