Can Blu Tack® leave marks on surfaces?
Bostik Blu Tack® is designed to be removable, but on some surfaces it may leave an oily mark, particularly if it has been in place for an extended period.
To minimise the risk of marking, remove Blu Tack® carefully by rolling it away from the surface rather than pulling it off. If any residue or marking remains, see the How to Remove Blu Tack® Stains from Walls guide for detailed cleaning advice.
