Grout Pen White Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pens - White, Narrow 5mm Tip (7mL)

It works, but you have to keep applying. Get several because the brush smashes down quickly.

Basically, this stuff paints your grout. It does a fantastic job for about 15 minutes - then the tip becomes frayed and the paint runs out. Would give it 5 stars if it lasted longer. See my before and after photos of my kitchen tile counter. It doesnt clean up all the dirt in the cracks but does cover most of the uglies.

Did not last long

Works but not much in the pen. Would need many to cover a large area.

This is a repeat order. Love this product. When your grout is dirty and nothing seems to help, this will work wonders. Easy to apply, long lasting.

Here is a picture of a small section I’ve done on my bathroom wall. You can see it makes a pretty big difference. This is just 1 coat and it did soak into the grout pretty well. I went out of the lines onto the tile a little, so I let it dry and then wiped it off with a wet wash cloth. It came right off of the tile but stayed put in the grout, so I’m hoping once you let it really soak in well it’ll stay even after washing the wall with cleaner. The pen has the be shaken and depressed every few minutes, so that’s a bit of a pain but it works just a Sharpie paint marker. My bathroom is pretty small and I’m eager to see how much just 1 pen covers. I’ll likely buy again.

I found it very easy to use and it instantly refreshes old grout lines to look like new! I used this on our white tiled kitchen counters and island, the area that gets the most discolored from food. I used to use white paint with a small paint brush to refresh the grout in the kitchen, but that would take time and start to peel off and not last that long. If chunks of grout actually came out (rare), I assume Id need to mix some grout and fill it with that, but for discolored tile, I just quickly use this on top of my old discolored grout lines, and its fantastic, I would buy this again for my needs. it probably helps that the tile is white too, but if i go over the grout line onto the tile, it easily comes off the tile. I just got this pen, so i couldnt review the longevity or easy to remove yet. I also dont know how this would work in the shower where water gets on it all the time, our shower tiles dont have white grout and arent discolored. But for the kitchen with white tile and white grout, its so far ideal!

Love this grout pen easy to use and makes my grout look like new

Does exactly what its advertised to do but make sure you actually have WHITE grout before using it, otherwise your results will be freakishly bright. Wish they made these in other colors, like pale grey and beige...

Easy to use. Pen ran out fairly quickly
