Hi Terrie: Try one of these:
1/2 cup dawn blue dish detergent, 1/2 cup white vinegar, heat the vinegar untl hot add the dish soap. put in clean spray bottle .and spray liberally let it work for 20 min or so...wipe off and rinse.
Then, there's the magic cleaner! 2 oz dawn, 4 oz. lemon juice, 8 oz. white vinegar, 10 oz water mix and put in spray bottle and spray the shower. Let spray sit over night and then rinse in the morning . You may use this to clean the oven..no heat needed...spray and let sit over night then wipe up.
