Review: Easy, effective and decent price for what it does - I’m not normally given to writing reviews, despite the constant requests from desertcart to do so - but if I find a product exceeds expectations, or seems better than the desertcart reviews imply, why not let someone else know…even if it’s only the vendor. In this case I had very limited expectations of a grout pen to eliminate some dark marks in the grout lines of a fairly new bathroom. Viakal, soap and a nailbrush, bleach and citric acid had all failed to make any impact. A couple of shakes of the pen and quick wipe over the dark marks and Wow, it seems to work. Simple, effective and cheap. It’s only a shower room with 60x60 floor tiles, so only a couple of grout lines across the whole floor, couple of minutes later and the whole thing looks like new. I was sufficiently impressed that I even wrote this eulogy.
Review: Super idea - Great idea and so easy to apply. Freshens up grouting really well. 4 stars not 5 as you need enough pressure for the liquid to come out but that in turn means the tip of the pen gets wrecked quite quickly. Maximum tiles before pen unusable is 16 ish In my opinion it’s still worth it.
