We have been using Rocket BLAST for all our tile and grout cleaning.  This week while at a church cleaning grout that had been abused for 25 years, after cleaning with BLAST I knew hitting it with Grout Shock would improve the look. WOW!  This acid cleaner is the best I have ever used in 30 plus years.  At the low use rate of just 10 ounces per gallon, it is a game changer.  Thanks for formulating yet another great product, and for making my company look above the rest with your great products.

Grout Shock

Heavy duty acidic tile and grout cleaner that smells fantastic!

With a pH of 1, Grout Shock is an extremely effective acidic tile and grout cleaner, using a phosphoric acid-based formula plus two additional solvents to clean grout when alkaline cleaners fail to produce the desired results. It removes embedded soils with ease. Use as a second step after your alkaline-based product when needed.

Grout Shock will dig into the grout much deeper and help remove stains, discolorations and other hard-to-remove soils, helping to restore the brand-new look of your floor.

Even if you got a good result from your alkaline cleaner, Grout Shock can still brighten and even out the overall appearance, providing you with a better end result and a more satisfied customer.

If used as a second step – after the Alkaline cleaner has been neutralized and rinsed from the floor, force dry the floor with a fan for twenty minutes, then apply Grout Shock, let dwell and rinse with Radical Rinse to neutralize.
