Actichem Crete Clean is a "safe-acid" cleaner and concrete residue remover. Crete Clean is an advance in the chemistry of removing concrete and grout residues from mixing and transportation equipment. Highly effective as a heavy-duty concrete cleaner, which is also used for cleaning concrete tools and equipment. Ideal for removing grout smear and concrete splashes from tiles and walls. Crete Clean is a low pH organic salt that has been blended with biodegradable wetting agents. Crete Clean is based on unique technology known as acid-replacement chemistry, and although low in pH, does not contain traditional acids such as Hydrofluoric, Hydrochloric, Sulphuric, Phosphoric, Nitric, Citric, Sulphamic, Oxalic or Glycolic. The organic salt, due to its low pH, acts as an acid during the cleaning process but lacks the adverse effects of traditional acid cleaners. Providing the user with all the concrete and grout residue cleaning and removal power needed, without the associated dangers of using an acid.

Benefits

Biodegradable – Phosphate-free and does not contribute to the eutrophication of waterways.
Safety – No acid burns, no fuming, it is a non-hazardous good, saving transport costs.
Waste water systems compatible – Crete Clean has very low COD and BOD levels, making it an excellent choice for areas with waste water systems. It is, however, recommended that pH readings be taken to ensure wastewater pH complies with water board recommendations.
Excellent Cleaning Power – Outstanding results when used in brick and paver cleaning.

Application areas and surface suitability

Excellent for builders' clean-ups, restoration, washrooms, and pool surrounds.
Safe for use on all artificial tiles.
Use with care on sandstone, quarry tiles, terracotta, grout and slate.
It can be used on all concrete mixing and transportation equipment. NOTE: Not suitable for use in concrete batching systems where the wastewater is reused for concrete manufacture.
Improved corrosion profile, Crete Clean outperforms traditional acid cleaners on both ferrous and non-ferrous metals. When used as directed, corrosion is negligible, and even in its undiluted form, the impact on ferrous metals is almost undetectable. However, as a low-pH product, Crete Clean can still cause corrosion when metals are submerged for extended periods, and polished surfaces may show marking with prolonged exposure.
Not recommended for use on acid-sensitive surfaces, including engineered stone, terrazzo, marble, limestone, granite and other natural stone.

How to use

Read and understand the SDS before use.
Always pre-test in an inconspicuous location for substrate sensitivity to chemicals.
Crete Clean is hazardous and appropriate care should be exercised, including the use of suitable protective gloves, goggles and protective clothing.
