## Questions & Answers

**Q: The Grout Pen I received has a dry white tip, is it broken or did I receive the wrong colour?**
A: Tips need to be primed before use, all brand-new Grout Pens have a dry white tip until they are activated.

**Q: The tip of my Grout Pen fell out or is worn down, is my pen broken?**
A: Tips are designed to be removable so when a tip becomes worn or damaged it can be taken out and flipped over. If the tip falls out do not worry, simply put it back in and keep working.

**Q: Do I need to press down hard while moving the pen along the grout lines?**
A: Pressing hard will damage the tip. It's better to prime the pen by pressing up and down until the ink flows to the tip. Once the tip is fully saturated, lightly move the pen across the grout line.

**Q: The colour of the pen cap is not exactly the colour I want**
A: The Grout Pen colour chart is a good representation, please keep in mind that computer screens can display slightly different colour spectrums, it is recommended to do a small test area first if you are not sure about the colour.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked well on floor tiles
*by N***C on 27 September 2025*

Great worked well

### ⭐⭐⭐⭐⭐ Excellent
*by A***R on 28 October 2024*

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 !

### ⭐⭐⭐⭐ 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!
