what gets blu-bastard-tack off of walls?

[AllieBongo]

this, along with bogies, has been left all over dd's bedroom walls by previous owners. How can I clean it off ready to paint??

other blu-bastard tack rolled over it

Blue bastard tac usually works quite well on the blue bastard tac if you rub a ball of new over the old.

Bogeys? Sugar soap solution perhaps?

i have none. it is banned. shall i pick enough off and ball it up to lift the other stuff.

mr muscle got them buggers off the day we moved in
