Miracle Cleaner Into a spray bottle mix: 2 oz. Dawn Dishwashing liquid 4 oz. Lemon Juice 8 oz. White Vinegar 10 oz. Water This is powerful stuff! If your shower has a bad build-up of soap scum and crud it may take a time or two to get that shine. I've used this to clean my OVEN.....my STOVE grates and the Glass in the showers....This stuff is AWESOME!!
slip grate into gallon size ziploc bag. Do not put any holes in bag. Pour 2-3 T. ammonia into bag. Seal bag & let sit for 12 hrs. Do this overnight. Take grate out of bag in kitchen sink. Rinse the grate thoroughly and scrubb with a nylon scrubber.
