VIPER Renew is used when all other cleaners have failed, and is a safer alternative than aggressive acids like phosphoric and muratic. The proprietary organic acid is twice as effective in dissolving calcium carbonate than phosphoric acid, yet is classified as only a mild skin irritant. Viper Renew will readily remove the embedded soil layer thereby renewing the surface of the grout.
