Hi - when we first moved into our house we couldn't afford proper backout blinds. We got some temporary ones that were fixed up to the window using velco strips. The velcro stuck around the window frame.
They ended up being stuck up there for a good few years in the end.
Now we have proper blackout blinds fitted, but the velcro has left sticky residue around the window frames (four windows). It attacts dirt and grime and I'm desperate to properly remove it all.
I bought sticky stuff remover but it was a very runny liquid so it was useless for use on a vertical surface.
I'm looking for something thick and pasty that I can paint on and then wipe off with a cloth.
Does such a thing exist?
