HYDROCHLORIC ACID 32% (HCL) is an industrial strength acid commonly used for the removal of scale, lime, calcium, oxides, efflorescence, bore stains, concrete dust and hard water deposits.

NOTE: this is a higher grade hydrochloric acid than the “spent / recovered” type normally found at your local pool shop or hardware store.

Use Recommendations

This product is generally used at concentration from 1:5 to 1:10 parts water depending on application. The product can be used via immersion, swab or recirculation techniques. The time taken to descale most items is approximately 5 to 10 minutes. Such a wide time span is given because results vary depending primarily on scale type and build up, dilution ratio and temperature. Once a surface has been cleaned always flush with copious amounts of water to removal all acid residues.


  • Before using the product ensure the surface has been pre-cleaned with appropriate cleaner to remove unwanted oil, grease and film.
  • If the surface is porous (ie bore stain on brick wall) then the surface should be well wetted to avoid acid being wicked into the surface and creating a white haze in the days following, as minerals are leached to the surface.
  • Once a surface has been cleaned the acid should be washed off as soon as possible with copious amounts of water.
  • Repeated acid washing may damage some surfaces.
  • This product may etch, lighten or alter the color of tile, grout, stone and metal surfaces.
  • Allow all new grout, concrete, cement or masonry to cure per manufacturers specification before using.
