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.
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.
