HCR-66 is a superior hardened concrete remover and cleaner. The HCR-66 formula is non-fuming and contains a special corrosion inhibitor to protect base metals during cleaning. It should be applied as received or diluted 1:10 for light duty cleaning.

HCR-66 may be applied directly to painted surfaces such as concrete mixers, trucks, tool and oil field cementing pump equipment.

HCR-66 is also safe to use on concrete as a stain remover. Heavy oil deposits should be removed with DGC PLUS, then follow with HCR-66 for a brightened effect.
