Review: Saved a huge job - The tile floor in my ensuite had grey grout which was worn and very faded. Cleaning it didn't really do the trick so gave this pen a go. One pen was enough to cover my entire floor and looks so much sharper and nicer. Was very easy to use and the excess was easy to wipe away with no issue. Had zero problems using this. Couple of shakes and a few presses primed the pen and every so often I would put the lid back on, shake and dab it a few times to get the proper consistency required to continue on. Review: Excellent - Exactly what I was looking for! White tiles and grout I was struggling to get it clean when a friend suggested a grout pen! This did the job perfect , so easy to use and although I bought a pack of 2 I only used 1. Really pleased with the result ! ## Features - Contains 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl- 2 H-isothiazol-3-one and benzisothiazolone.

White tiles and grout I was struggling to get it clean when a friend suggested a grout pen! This did the job perfect , so easy to use and although I bought a pack of 2 I only used 1. Really pleased with the result ! ### ⭐⭐⭐⭐ Best thing I've found! *by Z***E on 9 January 2024* This has easily got to be the best little hack I've found however it isn't working so well in the areas where there is often water (eg shower area) so have to go over it. You also have to make sure the area is dry otherwise it messes up the pen and it stops working properly! I've ordered about 6 now and it's slowly transforming my kitchen and bathroom! ## Frequently Bought Together - Grout Pen Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Narrow 5mm, 2 Pack with Extra Tips (7mL) - Grey - PentaUSA Tile Grout Repair Kit - White Grout Filler, Triple Protection, Fast Drying Formula Restores and Renews Grout Lines with Scraper (White, 8.8oz / 250gr) - Grout Pen White Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - White, Narrow 5mm Tip (7mL) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/376936489-twin-pack-grey-grout-pen-designed-for-restoring-tile-grout](https://www.desertcart.pt/products/376936489-twin-pack-grey-grout-pen-designed-for-restoring-tile-grout) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-07*
