I use Blu Tack quite a lot in my day to day work - keeping things in a fixed position while working on them etc... But I have noticed that after a couple of weeks of usage they become quite dirty either with dust or bits picked up from around my desk which have now become trapped in the Blu Tack's grasp.
Does anyone know of anyway to clean these bits out?
It is making the tack slightly less sticky and not working as well as I would like. I don't really want to buy more of the stuff so if anyone knows anything that would be of help - I would appreciate you divulging said information!
For people who don't know what Blu Tack is I have put a picture below: (not that you'll be much use if you haven't heard of it)
It is used as a way of temporarily affixing something to something else, usually posters to a wall and things like that.
