Questions & Answers

I have dog urine on my tile and grout, will Zep help clean it?
ByAug 1, 2026
1 Answer | 
Answer This Question

Hi Sandra, this product is only meant to be used on grout, not to clean tile. We'd recommend cleaning the tile first with Zep Foaming Shower, Tub, and Tile Cleaner. Then, for more heavy-duty grout cleaning, using Zep Grout Cleaner and Brightener on your grout only. Please see the label for proper usage instructions.

    Hi Gayle, we cannot recommend this product for any use not listed on the label. This is a powerful, acidic product that should only be used on grout. We recommend Zep Shower, Tub, and Tile Cleaner to eliminate soap scum.

        Hello, this product has a brightening effect so it may help to remove the appearance of mold in grout lines, but it is not formulated to kill mold. Please see label for proper usage instructions. Always test in an inconspicuous area before use.

              Can I use this on the blackened grout in a fiberglass shower stall
              ByFeb 28, 2026
              1 Answer | 
              Answer This Question

              No, we wouldn’t recommend this for blackened grout. This product is intended for use on white or colored grout lines on tile floors. Please refer to the back label for proper usage and safety instructions.

                Will this damage porcelain tile if left on more than 3 minutes?
                ByNov 30, 2025
                1 Answer | 
                Answer This Question

                That is possible. This product is not meant to come into contact with tile and should only be used on grout. We recommend wiping off any excess product and if it comes into contact with tile for an extended period of time, please rinse the tile with water.

                  Oh yeah Zep WORKS!
                  I bought Zep Grout Cleaner and Brightener after my friend recommended it! I am so pleased. With a little bit of elbow grease, time and the Zep cleaner, my bathroom floor looks amazing! The Zep made the scrubbing so much more efficient. Just follow the directions on the bottle. Really its that simple. It was wonderful to see grout lines brighten, stains removed, and cleanliness restored! I'll be honest I had not cleaned the grout in this bathroom for over 25 years. Never thought about it, had much better things to do. Wow! Zep handled this job!! Thank you Zep makers!!!!

                      Amazing!
                      I barely ever leave reviews, so believe me when I say that this stuff is fantastic. The key is patience. You just put it on the grout wait the full 3 minutes, agitate with a brush, wipe up, and then wipe off with a wt cloth. Easy peasy and the results are great!

                        I love this Zep grout cleaner!
                        I have been using this grout cleaner to clean the grout in my kitchen floor tile and it’s been amazing. It literally bubbles up the dirt and junk in minutes. You do a little bit of scrubbing and it’s gone. I don’t know how you could make it any easier. I highly recommend this product.

                          I chose white grout not thinking how dirty it would get. This stuff is amazing!!

                            Absolute SORCERY
                            If a cleaning wizard concentrated magic, liquefied it and crammed it into a bottle, it would be this stuff. In fact, I think that’s how all Zep products are made. My fiance bought his home 17 years ago and just used a WetJet Swiffer for years. Once I moved in, I introduced a proper mop and did a deep clean… or so I thought. Knowing the grout was not supposed to be a dingy gray/brown, I decided to try the Zep Grout Cleaner & Brightener… I had no clue the grout was pale peachy PINK!

                              No Elbow Grease Required
                              Just apply the product, wait a few minutes, brush gently with a grout brush, and wipe. So effective and so easy. In the picture, the top area has been cleaned. Worth every penny!

                                Excellent product
                                We did not leave it for 3 mins. We used a tooth rush to scrub right away to prevent the tile from getting Duke and it worked so well! Our tiles look brand new again!

                                  Works great. Let solution soak for about 5 mins and very little scrubbing wiped with wet paper towel...cleaned really well can see the original color
