Removing marks from Tiles

[Angling mad]

I have just had a new CH boiler fitted and the Plumber had to slide the boiler into place across a couple of large tiles to get under a worktop. As a result I now have a few scratch lines which is largely the galvanising which came off the base plate of the boiler. Can anyone please advise how best to remove this if at all possible.

Thanks

Always start with the least aggressive methods first, my usual preference for anything that I know isn't a deep scratch is to try a rubber (the kind for pencils you dirty minded lot), if that doesn't work then a non-abrasive cleaner and a cloth/sponge. If either of those don't work then it gets into dodgy territory where I wouldn't want to make a recommendation without seeing the problem at hand, using the wrong method could make things a lot worse.

Thanks for the rubber tip but afraid it did not work for this in end we got the marks out with Bar keepers friend powder which seems to be a superb cleaning product

Glad to hear you got it clean. I have heard good things about Barkeepers friend but if I am not mistaken it is an abrasive so use with caution.

the wife read up on it and it appears not to be abrasive and recommended by Corian and Wegdewood for removing stains, cleaning , restore and polish. It is Citric based. She uses is to clean the ceramic hob better than hob brite so at least it wont sit in the cupboard with all the other bottles of stuff that never gets used

My googling finds sites saying it is abrasive and others saying it isn't. It seems no-one knows haha.

If soap scum or water spots have dulled the ceramic tiles around your sink or bath, bring back the brightness by scrubbing them with 1/2 cup white vinegar, 1/2 cup ammonia, and 1/4 cup borax mixed in 1 gallon (3.7 liters) warm water. Rinse well with cool water and let air-dry. Use a toothbrush or the edge of a sponge to clean the grout with the solution. Take care not to get the bleach solution on the tiles.
