Earth Friendly Grout Pen Bag Bag 2 Oz

I first used this pen many years ago when I first moved into my apartment. My bathroom had a white tile floor with grout that had become very dark and dirty. A good tip- I did not try to do the entire floor at one time. It is very tiring. Instead, I tackled a small section at a time - about 12x 12 for a section of 2" square tiles. This approach made it easier to walk on dry areas while the new work was drying. Although the grout still looks better than when I first moved in, I recently decided to redo it. Like a fresh paint job, it provides an instant lift to the room. I wish they sold a pen in pale gray for my kitchen floor grout.

Nice grout pens. Works great! I bought the white color and it makes the grout look sparkling brand new.

Did a good job, but could have used another pen tip as it wears away.

You will be amazed at how easy these pens are to use and how great the grout looks afterwards. Clean the grout a little before you use and go at it. The pens are so easy to use my 8 yr old grandson did 2 bathrooms for me. It really makes the floors look clean and new again. You will be VERY satisfied with them. There is no easier or better product out there!

I used these pens to quickly refresh my tile counters for a family party. Amazing and fun to do! The tips lasted because you don't have to press hard to get a great result, it's like painting, you don't press the brush hard. It completed my entire kitchen counters. I recommend this product and will keep some at hand for a quick cover up instead of having to re-grout.

Works perfectly to give a clean new look to your grout. After a few weeks, no change of color or mold.
Why do I give 4 stars and not 5? The two pens in the pack have a single tip each. While using the pen, the tip deteriorates and get shorter. You can flip it but it does not help long. If you work on the ground, with gravity it can be easier but I doubt that this is enough to reach the official 160 feet promised. If you renovate the walls like me, this is worse and you have to press harder and the tip deteriorates faster. I had to unscrew the pens to access to the liquid left.
Add 3 extra tips per pen and it will get the 5 stars it deserves.

worked excellent on my tile counter tops that are over 30 years old

It whitens nicely. Won't do a large area and this is really only for wide grout - doesn't get in tight spots.

The pen is difficult to use! The liquid inside doesn't get on the tip much! Disappointing!

Waste of time and money. Could not even get the pens to work. The liquid would only come out when the tip was compressed, but when compressed the tip would not reach the grout between the tiles. I tried different angles and wore the tip down to after going around one tile. Perhaps this product is not to be used on floor grout? Pitiful. Just a pitiful product. Can't believe I fell for it. I was duped by the other reviews, don't let it happen to you!
