When the grout is permanently discolored due to never being professionally cleaned or properly sealed, grout staining is the last result before removing the grout and re-grouting. Re-grouting is not cheap, so the grout staining is a very logical way to go.
A strong alkaline detergent followed by a grout restoration acid detergent. Alkaline detergents are great general purpose cleaners. These detergents break down grease’s and oil’s and gets the grout ready for the grout restoration acid. The detergent is applied using a pump up sprayer to apply an even thorough consistent application of detergent. We want the tile lightly damp and the grout lines glistening.
A grout brush is used to work the detergent into the grout lines. The grout lines should stay wet with detergent for 20-40 minutes to allow the alkaline detergent to break down and emulsify the greases and oils in the grout. The grout is then rinsed using a truck mounted hot water extraction cleaning machine. This is a contained pressure washing system. Water is applied to the floor in a spinning cyclone that scrubs the floor with energized water that draws the dirt and detergent from deep within the pores of the grout. Vacuum ports on the edge of the rinse tool instantly sucks up the water keeping all the water contained under the wash head. This uses 1200 PSI of water pressure at 4.5 gallons per minute but never gets your floor more than mop damp. This will get the floor 75-90% as clean as new.
To remove the remaining stains in the grout the grout restoration acid is needed. Grout restoration acid detergent works by dissolving grouts hold on the material staining. This allows the stain to be rinsed from the grout. Grout acid will also remove moderate grout hazing, efflorescence, and grout color seal. The grout acid also opens the pores of the grout so it is ready to be filled with grout sealer. The acid detergent is applied in the same way as the alkaline detergent with extra care given to acid sensitive surfaces like marble and stainless steel appliances. These surfaces can be etched with the grout acid and should be covered with plastic and treated with extra caution.
