      How do I know which white to use? Your bright white looks beige and arctic white looks more white. Mine should be pretty white, which I would assume would be a bright white.

                  I don't bother with reviews much but this product was so easy to work with and it worked amazingly. before and after pics attached... black wood looking tiles with black or charcoal grout, I couldn't get rid of the pesky white haze, I tried vinegar also floor cleaners of 3 different types no luck until this product saved the day!!!. It does help to buy a bag of cheap rags for the quick clean ups and spot wipes then I just tossed them

                  The quality of the product is great. No concerns. The 4 stars is because this is not "bright white" IMO. I know whites can be hard to match. This white has a hint of cream/off white/beige. It's very apparent next to the bright white metal tile edging sold at Home Depot. I have not tried the Artic white to see if that's a more true white. The color swatch on the bottle is pretty true to the white color it is. The name just doesn't fit and is misleading.

                  I love the ability to apply a colored grout sealant at a reasonable price. This color made the grout lines almost disappear. It takes time to apply but worth it. Holding up very well. A person does need to wipe off any sealant that gets on the tile as they go. Also I suggest doing 2 light coats. Not taking a star away from the product but it's zero stars for Home Depot as this product had been opened and used. I didn't realize that until I got home which is 40min from the store. The area I used this on was small so there was still enough left. Just irritating as apparently the bottle was not checked when someone returned it. When I Iooked closer there was paint on the outside of cap indicating it was opened and used. The internal seal was gone.

                  New shower
                  Pleased with results, the bone color is a little more creamy than what I was going for but should have done this years ago. I couldn’t stand how dark my shower was and this gave it a complete transformation. Was harder than I expected to apply and clean up.

                    I been using this product for years now it restores the grout color and has transformed floors, backsplashes, showers, decks you name it. I recently used it on a travertine floor with 1/16 grout joint original color was linen and after cleaning the floor the owner wanted to change it to bone it look brand new i highly recommend using this product it works it really does wonders

                    Excellent Product
                    My 30 year old grout was badly stained, no cleaner would fix... Grout Renew save me from replacing tile. For prep I used a brush attachment on my drill with some soapy water to clean away dirt and oil from the grout. Next shake bottle well and pour a quarter size amount... Then use an small angled paint brush to apply product to grout, work it in well with back and forth strokes. Only apply to about one foot of grout because this contains a glue (epoxy) that dries fast. Then use a wet and wrung out "3M Commercial Sponge" to clean up excess product on tile. Dunk sponge in bucket with clean water, wring it out and repeat the whole process. This is a slow process... Start in an inconspicuous area like under a couch.

                      I have several colors of this grout colorant as I’m treating multiple rooms. I treated the grout in a bathroom with the “bone” color, using two coats. It’s been a couple of months now and if I could give this product 10 stars, I would! It really revives the tires and stained grout, and created a strong seal. Now, instead of every bit of dust and dirt absorbing into the grout, it just sits on top and wipes right up. This product is well worth the effort to apply!

                      Love my refreshed floors
                      Chat GBT suggested the color Haystack for my tile floors and I love how it turned out. It was easy to apply and remove the excess paint.

                        Worth every penny, and then some.
                        Purchased Custom Grout Renew as a last chance option to avoid replacing our backsplash in the home we just bought. The tile backsplash was a white marble, but the grout was dark gray and looked horrible. Before replacing everything, I thought I would give Custom Grout Renew a try. WOW. The difference was night and day. An 8 oz bottle covered all of our kitchen and fireplace surround with plenty left to spare.

                          Had an area with filthy and missing grout. Prepared area, clean and dry. Used a cheap toothbrush with only 2 rows of bristles, (I cut the rest away) I applied working a small area at a time, wiped excess with baby wipe. Perfect! Restored floor to looking like new!
