<p>I’d try denatured alcohol in lieu of goop, goof-off, lighter fluid, mineral spirits or turpentine. Those have a longer evaporation time as opposed to denatured alcohol, or a solvent like lacquer thinner, or a painter’s deglosser like Imperial’s wil-bond. </p>
<p>It’s imperative that if it is a gas dryer with a standing pilot light that you might want to call a pro unless you are “handy”. The pilot light should be out, and the gas valve closed before attempting to use any of these petroleum based solvents. These are all extremely flammable, and may easily ignite in the confined space of a dryer drum.</p>
<p>An electric dryer or a newer gas dryer with electronic ignition can be done safely by yourself. Try the solvents (denatured alcohol, lacquer thinner, or wil-bond, whichever works… my basic experience is if wil-bond doesn’t remove it, it’s probably not going to come off). </p>
<p>After you clean it, leave the dryer door open at least an hour. Then run a cycle or two on the air only (NO HEAT) setting to evacuate any remaining vapors.</p>
<p>I’m a building trades pro, and the son of firefighter with 40+ years in the service… this is potentially a disaster in the making… please heed my precautions.</p>
<p>Additionally, the solvent may dissolve some of the drum paint. No permanent harm there, just don’t be surprised if it happens.</p>
