What a grout guard restorer 8 oz is actually doing
Grout is porous cement, and porous cement absorbs whatever touches it – soap scum, coffee, mildew stains, and plain water. Once grout darkens or grays, ordinary cleaning can’t reverse it because the discoloration is inside the material, not on top of it. A grout guard restorer 8 oz works two ways at once: it deposits color back into the grout line to restore a uniform look, and it seals the surface so the next spill sits on top instead of soaking in.
Why the 8 oz size
The 8 oz bottle is sized for a single small-to-medium room – one bathroom’s tile floor and shower, or a kitchen backsplash – without leaving a half-used bottle to store afterward. For a whole house or multiple bathrooms, our 16 oz and 40 oz grout restorer sizes cover more square footage per dollar.
Applying the grout guard restorer 8 oz
Clean the grout thoroughly first and let it dry completely – restorer applied over trapped moisture or soap residue won’t bond properly. Apply with a small brush or applicator along the grout lines, following the lines rather than dabbing, and wipe excess off the tile surface before it dries. Allow the recommended cure time before the area gets wet again.
Keeping grout looking restored
Once sealed, stick to pH-neutral cleaners on tile and grout – harsh acidic cleaners will break down the seal faster than normal wear. Wipe up standing water in showers when you can, since grout that stays wet longer stays vulnerable longer even when sealed.
Grout guard restorer 8 oz questions we get asked
How long does 8 oz cover? Enough for one bathroom’s floor and shower grout lines, or a similarly sized area – exact coverage depends on grout line width and spacing.
Do I need to clean the grout first? Yes – restorer seals in whatever is already in the grout, so cleaning first is what makes the color come out even.
How often does it need to be reapplied? Most bathrooms hold up well for a year or more before needing another pass, depending on traffic and moisture exposure.

It is my pleasure to send you an email commending your product. We built my son’s bathroom 6 years ago and I did not know that the grout lines would become so soiled. Especially around the toilet and shower. I used hydrogen peroxide with no results. Researching the internet, I found your Grout Cleaner/Restorer & Grout Guard Protector to seal the grout after cleaning. I am very pleased with the results. The grout cleaner application and rinse was very easy to do. The sealer was applied to all grout joints in 30 minutes or less. I had fabulous results from your product and the bathroom floor looks brand new again.

I recently used your grout cleaner products, The Restorer and the Grease and Grime Buster. Unbelievable!
When we remodeled our kitchen we used tile on our counter tops but never really thought to use a dark color grout. The off white that we used has become terribly stained in certain areas. Spilling coffee will really do the trick. I have tried a number or products and nothing has worked. I felt doomed to live with brown grout. I saw the article in Martha Stewart Living and clipped out the information on your company and the products you offered.
I am extremely happy with your product and would recommend it to everyone with off colored grout.

Saw that Martha Stewart recommended this product, I researched and found it was true and that it was mentioned on her website. Great product – was cheaper to that in the store and worked better than past one’s we’ve used before

unbelievable product – works fast Review by Superdad
my wife complains all the time about our dirty kitchen floor; the floor is 7 years old, the tile is clean but the grout around the fridge and stove is really dirty. tried a lot of grout cleaners, none have done the job; until I used this grout restorer product, I mixed in a little of something called grease and grime buster and with a little bit of scrubbing with a brush; the grout became brand new again. I cleaned all the grout in about a half hour, unbelievable!!!

This is the best grout cleaner ever – far superior to those you buy in the chain stores. Spray on and watch the dirt rise. Have recommended this to several of my friends.
