I have not seen this product mentioned here before: Dawn Platinum Plus Powerwash Dish Spray. I sprayed the Ensolite, let it soak for an hour, scrubbed with a stiff, wet brush, then rinsed. It takes three passes with a wet rag, changing water each time, to remove the soap residue. The surface is cleaner than I've ever seen it, and is no longer sticky. Hopefully, it will stay that way.
