Heritage Cleaning Chemicals For Stone, Render & Masonry

This natural stone cleaner chemical contains no biocides, acids or bleach. Having a pH-neutral all-natural chemical which is effective and will not damage the stone to maintain the natural beauty of the stone while effectively cleaning it. An excellent stone cleaner for heritage buildings, conservation projects, memorials and statues that is low risk for operators and stonework alike as it is safe even in a water course and won’t kill grass.

Natural Stone Cleaner

Increasing demand for environmentally friendly and safe-to-use yet effective stone cleaning products in cleaning of stone has led to us producing StoneKleen, an innovative cleaner that can make your life easier and safer. It is available in both 5-litre and 20-litre jerrycans with quick delivery UK-wide.

How Does StoneKleen Work?

It works by using nano-tech energy particles that penetrate and dislodge dirt, oil, grease, or algae. It does this by breaking the surface tension that holds dirt or algae embedded on a substrate.

Many a ‘dirty’ looking patio, headstone, or natural stone wall is suffering from an invasion of living microorganisms called algae that thrive in our damp climate; with StoneKleen applied generously they are loosened off ready to be washed away by hose or just rain and the weather over time.

StoneKleen is a pH-neutral natural stone cleaner product that can be used successfully on terracotta or travertine, granite, sandstone, limestone, green slate, porcelain, clay tiles, terrazzo, concrete, ceramic tiles and artificial stone. StoneKleen is available as a pre-diluted (pour out and use) or as a professional quality concentrate that is normally diluted at 1 to 10 with water, the latter is often used by contractors and exterior cleaning firms.

One of our mottos is ‘Cleans Not Kills’ and this natural stone cleaner does this in contrast to biocide-based stone cleaner chemicals that are for deadly for aquatic life and less than ideal for lawns, pets, or flower beds.

Natural Stone Cleaner

The cleaning action is powerful yet non-corrosive, non-acid, non-toxic, and non-hazardous and this cleaner product is even certified as food safe and is safe to use near a water course. It is supplied in 5-litre bottles or 20-litre jerry cans as a ready-to-use cleaner and is ideal for patio and concrete and hard surface cleaning.

How To Apply StoneKleen:

Wondering what is the best natural cleaner for natural stone? Apply this StoneKleen chemical detergent by pouring on or with a brush, sponge, roller or low-pressure sprayer, saturate the surface well and then agitate with a stiff brush.

If sprayed you will often benefit from more than one application, wait 5 minutes before rinsing off and your brush may need to be rinsed to relieve it of debris and soiling between applications.

The use of a pressure washer in conjunction with this natural stone cleaner is helpful for outdoors but older stone masonry needs care and a low pressure setting and it is a good idea to test an area first – we also have a video of how to apply here.

This stone wall cleaner chemical kills nothing! An odour-free, pet-friendly, and certified food-safe chemical for humans as well as being pH neutral, StoneKleen is a refreshing and environmentally friendly change from potentially harmful biocides and pungent Sodium Hypochlorite.

The Best Way To Clean Stone Walls – Step-By-Step

Brush off loose debris from the concrete or stone wall to be cleaned.
Apply from a low-pressure sprayer or pumped extending pole brush – DO NOT DILUTE.
Select a manageable area to focus on, say a metre or 2 squared and apply generously.
Brush in well and agitate with a stiff brush – you will see the dirt and algae start to colour the foam.
Rinse off the areas treated with a hose or lightly with a pressure washer.
Repeat as needed, on very old dirt and algae several applications may be needed.

Perfect as a stone wall cleaner in churches, war memorials, monuments, and older properties it is all natural and pH neutral. StoneKleen can also be used on interior stone and tiled or brick walls and on limestone or sandstone floors. Available in 5 litres (£24.00) and 20 litres (£80.00) jerrycans.

A readily biodegradable product that is safe in drains as a run-off and in any watercourse or aquatic environment, this gives a whole new level of eco-protection and pleasantness to use all day long!

Breaking the surface tension that bonds dirt to stone walls is not only ideal for the initial cleaning but also secures a surface that resists the re-infestation of algae or dirt gripping back on.

Stone Wall Cleaner

This means the clean appearance on stone walls, driveways and patios lasts for longer although the product itself is non-toxic and non-hazardous and very safe and stable to store and use.

Contains no biocides, disinfectants, bleaches, acids, or alkalis. Please contact us to discuss your stone wall cleaner challenges and also see our exterior cleaning equipment range.

Our all-natural detergent cleaner chemicals are supplied as ready-to-use aqueous cleaning solution and are highly effective cleaner chemicals that are safe for use near or in a water course or any aquatic environment.

The BoatKleen, BuildKleen, StoneKleen, RenderKleen and Marine Algae Cleaner products contain no acids, alkalis, biocides, bleach, or disinfectants and are both pH neutral and certified as food safe.

Cleaning Chemicals Safe To Use Near Watercourse

As well as being ideal for cleaning of outside paint work, cladding, concrete, pontoons, slipways, and natural stone surfaces, bridges, painted cast iron railings and so on, the chemicals have very little or no odour and users or staff do not need to wear any PPE items.

Any statues, walls, pontoons or infrastructure in docks, yacht clubs, city centres or near rivers can be cleaned successfully with BuildKleen without any worries about biocides getting into the water or needing an environmental discharge licence from Environment Agency, Natural Resources Wales or SEPA.

These astonishingly safe, stable, and effective chemicals are neither harsh nor caustic and yet use advanced formulation to deliver a substance that gets underneath soiling, dirt and algae to dislodge it by breaking the surface tension holding it in place.

Eco-Friendly Boat Cleaner

It is important to agitate the surface once you have sprayed or poured the solution on to it as this is essential in setting off the process of breaking surface tension to generate a super clean surface that will also tend to resist being re-infested with algae etc for longer.

Reach And Wash system

The AcuteClean application kits combine a series of carefully chosen commercial reach and wash systems and professional pump trolleys often used for what is commonly known as ‘softwashing’ with harsh chemicals like Sodium Hypochlorite.

However, we have optimised this equipment into a robust and focused pump system that give the ideal starter kits at a good price for applying our unique exterior cleaning eco-friendly chemicals because the application and all-important agitation can be done in one pass with the pole brush.

We have carefully researched the best of professional quality carbon fibre water-fed pole brushes, and selected a stiff brush that is ideal for render, concrete and roofs or a softer brush option for fascia’s, cladding or signs so that you have the perfect recommended system to operate for many years.

The package kit on this page uses a lithium-ion battery that will often give 12 hours of use, all fittings, hoses, water-fed brushes and a choice of 2 x 20 litre jerrycans to get you going!

The price for the complete package is £3200.00 + VAT – please see the link below:

A high-performance monument cleaner chemical which dislodges dirt, grime and algae from natural stone or marble with ease and very little possibility of damage to surface or structure, StoneKleen is perfect for cleaning war memorials or monuments as well as stonework on heritage or listed buildings.

This remarkable chemical is an aqueous cleaning solution which was invented in the UK and is made here as well. A remarkable breakthrough in the use of nano-energy particles to penetrate and lift off soiling by breaking the surface tension holding the dirt to the substrate.

How To Use StoneKleen:

Apply this monument cleaning chemical by sprayer or hand soft brush, gently agitate with a semi-stiff brush to achieve a light foaming which will typically turn the same colour as the soiling – e.g., it will turn green when it is removing green algae.

After several careful applications with a 10-minute wait we suggest generous rinsing down with a garden hose to help carry off soiling and dirt rather than letting it dry back in again.

How Is It So Safe To Use?

An odourless, stable, and ultra-safe chemical, StoneKleen is a certified food-grade product that is pH neutral and contains no biocides, disinfectants, acids, or bleach. It does not set out to kill organic growth like so many exterior cleaning and ‘softwash’ products do but rather to dislodge it ready for rinsing off or weathering off over time.

Staff working with StoneKleen do not need to wear any items of PPE and the packaging need carry no hazard warning pictograms – meaning it is safer than Fairy Liquid! This remarkable product is formulated in a unique manner from all-natural ingredients and used widely in the food industry for cleaning and hygiene.

Monument Cleaner Chemical

Is It Effective At Cleaning?

Yes, it is remarkably so. You will prove a rapid dispersal of soiling which outperforms almost any other product apart from strong sodium hypochlorite which is nowhere near as environmentally friendly and would need full masks for users.

Hypo is unlikely to be suitable for listed monuments any way whereas StoneKleen is a huge help in combination with distilled water. Please note that StoneKleen is safe in any aquatic environment and water course.

How Much Does It Cost?

StoneKleen monument cleaner is delivered at ready-to-use strength in 5 litre or 20 litre jerrycans and is delivered all over the UK by courier – order online on the links below. Please note you can pay by card and don’t actually need to have a PayPal account although this is not very easy to see.

Using StoneKleen cleaner inside is similar process to above outside process on a smaller scale, the rinsing is not an absolute must but keep in mind that if significant amounts of dirt are liberated then you don’t want the residue to dry back in again!

Monument Cleaner Chemical

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.

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.

Cleaning rendered walls is easier when a render stain remover like our RenderKleen eco-friendly chemical gets into action and transforms the walls of your building. This ready-to-use chemical is an eco-friendly all-natural detergent that was designed for removing algae on harbour quaysides amid concerns around chemical discharges into water courses – it’s available in 5-litre or 20-litre containers.

Render Stain Remover

RenderKleen render stain remover is becoming more common in maintenance and the building trade and it is a highly effective and safe product for cleaning rendered walls. It is a certified food-safe product so will cause no harm to us or our pets and the airborne spray and run-off is harmless to humans or aquatic life.

For larger applications cleaning contractors often choose the super concentrated version packed in 10-litre jerrycans – see on this link.

How Does The Render Stain Remover Work?

This detergent is different from most conventional cleaning chemicals in utilising nano-energy packages that penetrate deeply and lift off the algae and dirt leaving a clean surface that also lasts for longer than when treated with sodium hypochlorite (bleach) or a biocide-based soft wash render treatments.

RenderKleen 20 Litre – £80.00 + VAT Each – Accepts Credit + Debit Cards

You could think of these nano-energy packages 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. The key point is that the soiling and stains are dislodged instead of being killed as a biocide does.

Safe And Stable

Non-hazardous, non-toxic, and having zero biocides, acids, or bleach, we believe this render stain remover is one of the best-value render cleaner mixes out there and both more sustainable and much superior in results to cleaning render with bleach.
