You heat the back of them with a hairdryer as you slowly pull it off.
You can use a spot remover, but it might be better for the carpet, kids, and pets if you use a carpet steam cleaner that uses hot water. This will melt the glue and remove it easily.
That depends what kind of glue it is. -I would try Goof -Off for removing unknown glue from a carpet.
Difficult to say without knowing what exactly it is.-Name your glue -
Dip a rag in Goof Off and rub it on the carpet glue, it will soften enough to peel it off.
glue in my velcro
Depends on WHAT you are removing it from - partial facts are useless for an answer.
If the carpet glue is dense enough to affect your tile cement then you should remove it by sanding. -If it's only sparse then it won't matter.
No, there is no carpet glue in cigarettes.
Can I attach a piece Velcro to the back of a cell phone (plastic?) with Elmer's glue?
Carpet is almost always held down around the edges with nailed down tac strips. You just grab an edge somewhere and tear it up off the floor. You'll then have to remove the tac strips. Try pulling up a corner maybe and looking underneath. You'll see. note: it's possible it was glued down but you remove it the same way. The glue leaves a mess though and you gotta scrape it off. Hope not.
Try some good old fashioned finger nail polish remover. It works on super glue.
Most silicon based glues are good for sticking Velcro to almost anything.
