Tub Cleaner - vinegar and dish soap, no scrubbing! Heat 1/2C white vinegar in mwave for 90 sec, pour int spray bottle. Add 1/2C BLUE Dawn dish soap. Shake gently to mix. Spray on surface, let it sit 1-2 hours. Just wipe it away then rinse with water. Should also take soap scum off shower doors!
wish I knew this years ago- Right after using the grill, unplug it and place a wet double-sheet of paper towel between the lid and the surface. The leftover heat causes the towel to steam and clean the grill. Wiping it dry with another paper towel is all that’s needed. I'm going to try with waffle iron.
