DONQL 6Pcs Tile Pen Black Grout Pen for Tiles Bathroom with Replacement Nib Tips Anti-Grout black Tile Pen Marker for Restoring Tile Grout Wall Floor Bathroom Kitchen and Floor Tiles (Black)

Super quick and easy to use and handy replacement tips included. Quite messy to use but cleans up really easily, I just left it to dry for 24 hours and then wiped the excess away with a damp cloth. Have had many showers since and cleaned the bathroom and hasn’t faded at all so definitely water proof! Looks great, nice cheap way to feel like a brand new bathroom ☺️

Interesting stuff. I have a horrible bathroom tiled with ugly grey and pink tiles (I know!). For years I have nursed a fantasy that it might look better if I could change the tonal value of the grout. These pens are how to do that. They do it well! Some tips: 1. It's water based and its tempting to think you can wash off the inevitable excess as you go with a damp rag. Don't! The dye just runs everywhere and magnifies the mess exponentially! Instead, wipe of the excess with dry toilet tissue for a provisional finish. Then allow it to dry and then scrub lightly with a damp kitchen scouring pad to take of any remaining smears – I've been using a softer white scourer but may also try a green one too. 2. I thought my tiles had been laid by a real expert. Doing a contrast colour suddenly reveals the exact appearance of your grout. Even tiny variations in width etc will be detected by your clever human eye! Be careful what you wish for.

I used this to refresh tired and mildew stained white grout in the shower. From trial and error I can say this works really well if your grout is clean and completely dry before starting. I also allowed time for it to dry in before starting to remove over paint/dye from ceramics. It's comes off the tile easy enough with a light scrub. There are some areas I will need to go back over when its dry but I found the pens go a long way. I used less than 4 to do between these small floor to ceiling tilesin the shower. Good value for money, easy to use and extra nibs very handy.

Not that great to use

Easy to apply ,good quality ,really look good in my kitchen and bathroom and are waterproof they are just what I needed to change the look

Absolutely rubbish. The nibs just fell apart. They give you spares but definitely not enough. As for it being waterproof it isn't. I ended up using a tiny artist paint brush. Don't waste your money. Don't normally give 1 stars but for this it is a 1 star.

Easy to use and very good value for money

This is a really good product. Completely rejuvenated my bathroom and I’m in love. The key is to prep . Make sure all the tiles and grout are clean and dry before going in with the pen. Comes with extra nibs . The nibs do run down and fray after about 20 uses but you can get quite far before needing to swap them over. Each nib has 2 ends and you get 2 nibs per pen. Highly recommend! But as mentioned make sure grout is clean and dry. Grout can get stuck to any soap scum and be harder to remove . Normally wipes off with a dish cloth but if gets stuck to soap scum steel wool works great
