Pinterest user says "I just tried this - I will NEVER buy Comet, Soft Scrub, etc again. Used in the tub - sprayed on, left for about 1/2 hr - wiped down like nothing there. it is sparkling!" Will have to try!
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.
