Pry up the edge of one corner of the carpet padding with a pry bar. Start pulling the carpet away from the floor.
Cut the carpet pad off in sections with a utility knife as you pull it up, and toss the sections out of your way.
Place one prong of the needle nose pliers under any staples stuck into the floor. Turn or rotate the pliers so that each end of the staple comes up out of the floor.
Apply mineral spirits to carpet padding that is stuck to the floor with glue. Wet a rag liberally with mineral spirits, and apply it to the padding. Allow the mineral spirits to soak into the padding for 2 to 3 minutes. The mineral spirits will seep into the padding to the glue and loosen it.
Tuck a putty knife under the edge of the soaked carpet padding, and gently scrape loose.
Vacuum up any small pieces of carpet padding.
