Review: Great product. Easy to apply and refreshes discolored grout - Used this white grout pen to refresh our master bathroom counter tile and shower circa 1990. The grout was still in place but was discolored. It worked wonderfully! I used a paper towel to wipe off any overlap on the tile as I worked. I definitely recommend!

### ⭐⭐⭐⭐ Manage your expectations and it is a useful product. Very happy
*by L***R on May 26, 2020*

I was tired of looking at the greyed grout in my bathroom and I was hoping this would perk them up without the time and effort re-caulking would take, and it worked. It looks good. It was quick and easy to use and it has brightened up the walls. It feels clean and fresh again, without a painstaking full on caulk project. Now to address some of the negative comment made by others: For the tiles with cracked or missing pieces of caulk, they needed to be re-caulked. This pen was made to stick to existing caulk, it is not to be used to patch a crack or a hole, it really won't do the trick. The pen tip does get frayed but you can pull it out and turn it around and use the other side. It is not a super fine tip, so you may color outside the lines. This is not a big deal. Once it is dry, a straight razor blade will clean the edges quickly and neatly, It won't take long at all. I don't think the pen is a long term fix for high traffic areas, like the floor, the tiles that get hit constantly during a shower, or a counter top that gets cleaned multiple times a day. Those should be re-done with proper caulking. But I am very happy with the look of my refreshed bathroom and how little effort it took to get it.
