Linda Says:

Find powdered alum at the drug store. If you have trouble finding alum you can substitute 20 Mule Team Borax, which is found in the laundry aisle at the grocery store. Queen of Clean Extreme Tub and Tile Cleaner will do a great job on porcelain. For more difficult stains, use Queen of Clean Toilet, Tub & Sink Powdered Cleaner. Safe and natural but nothing cleans better!
