Did this today. Worked VERY well. I was surprised! Smell is strong but it gets the shower squeaky clean! Soap scum GONE! *Heat 12 ounces white vinegar in microwave until hot and pour into squirt bottle, then mix with 12 ounces Dawn dish soap & shake. I used 6 oz of Dawn. Spray & let sit for an hour.
Unclogging a clogged drain Naturally with baking soda and vinegar. This really works! 1/4 cup baking soda,1 cup white vinegar 1 large pot of boiling water. Let it stand for about 15 minutes. Then I poured a pot of boiling water down the drain.
