How to clean pen marks from granite

[phatboy]

Hi,

I have got some granite stepping stones for my garden. They have had permanent pen lines drawn on them, as they were going to get cut for someone else.

I now want to remove the lines, but I am having difficulty.

I have tried Cementone Brick & Patio Cleaner, power-washing, and Kent Acrysol, but none have made much difference.

Can anyone suggest anything else?

Thanks

The granite is a light grey colour.

not used it myself, but maybe this?

Thanks, graffiti remover looks like it could be the thing!

I will check what is available in B&Q this evening.

Cheers
