We had new carpets fitted this week and on the stairs I was gutted to see there was some old yellowed gloss visible on the sides of the staircase/bannister as they were a slightly different fit to the old carpets.
Enter…..a white grout pen! Tidied the edges up perfect and now gleaming white to match the rest of the staircase wood. No risk of spilling or running or blobbing the new carpet. Just wanted to share if it was useful for anyone needing to touch paint up in awkward places!
