Put dropcloths over the floor and against the wall. Open the windows to get a steady stream of circulating air.
Put on rubber gloves and spray a citric-based adhesive remover over the glue. Allow the remover to soak into the glue as long as directed by the manufacturer. This can be several hours.
Gently scrape away the paneling glue from the top of the wall toward the bottom. Repeat as necessary in rows from the ceiling to the floor until all the glue has been scraped away.
Clean the wall with steel wool, using less of the citric-based adhesive remover once the largest sections of glue have been removed.
Fill a bucket with 1 part TSP and 4 parts water. Clean the wall with a sponge dipped in the mixture. Rinse clean with an unused, damp sponge and let surfaces air dry.
