How can i remove blu-tack from a tablecloth without it getting damaged?

Question:the tablecloth is borrowed so i really dont want to stain it or anything but is there a way to get the blu-tack off it and if so what?

Answers:
You can freeze it off. or soak in warm water. add a small about of dish washing detergent to the water. Blue tack is a bit like chewing gum , even when the you get the gum out it always leaves a dull mark be-hind. So to remove the mark , you whip up 1 egg white , lay on top of the stain, leave for 10 min´s , and wash as normal. this little trick work´s , it´s not a joke
