Afterglow Floor Care incorporates all its advantages over the competition here. Clean and capture tools create no over spray and are E.P.A. compliant. Secondly, Afterglow Floor Care has the greatest mobile heating system in the industry. This system produces a whopping 750,000 B.T.U. of heat production and is thermostatically controlled by a computer. (The average carpet cleaning company can achieve about 100,000 B.T.U.) Heat is the key to cleaning grout. The higher the heat, the better the result. After the tile and grout has been steam cleaned a penetrating sealer is applied to the grout.
