adhesive

I have removed 9 of my 45 stick-on vinyl tiles from my bathroom (only 36 more to go!) I had to use a heat gun to remove them. They left a lot of old adhesive residue on the plywood to which the tiles were stuck. First I tried using mineral spirits to remove the adhesive from a 12-inch square...

Hello, I have been trying to hold things up against the wall (such as cords, picture frames, etc.) using 3M duct tape. It is not working too well. I am looking for a non-permanent adhesive solution that will do the job (don't want to put nails through these things, or into the wall either)...
