At Industrial Strength Cleaning we utilize powerful suction in combination with super-heated water (and high pressure for tile and grout cleaning), this combination alone flushes out deep, heavy soiling. But, to make our process stand up to the name "industrial strength" we first start with a spotting process which breaks down stains with dwell time. We then whip up a concoction of pre-spray that’s best suited for the specific soiling of your tile and grout and spray it down light to heavy. Once our rigorous preparation process has been done, we then proceed to use our hot water extraction process removing both our chemicals and your soiling. Most tile and grout comes out in excellent condition.
