Heat 1/2 C White Vinegar in microwave for 90 sec. Pour into spray bottle. Add 1/2 C BLUE Dawn Dish Soap. Shake gently to mix. Spray on surface and let sit 1-2 hours. Just wipe it away and then rinse with water.
Every month or two, give the pipes a good preventative cleaning to keep them clear of grease, oil, and hair clogs. Pour 1/2 cup baking soda down the drain, followed by 1/2 cup white vinegar. The mixture will foam up. Let stand for a few minutes to dissolve fatty acids, then pour boiling water down the drain to wash out any clogs. This really works!
