Allow the Play-Doh to harden, which takes about 24 hours. Once it has completely hardened, it will be much easier to remove. Take a sponge (not wet) and scrub on the dried Play-Doh. This will remove 95% of it. For the remaining residue, use an ice cube to gently lift the crums and goo off any surface!
