Bathtub Ring Cleaning by Dial-A-Maid Cleaning Service in Evanston, Il 60201. Bathtub Rings are the high water mark-a combination of body oil, dirt, soap, and hard water deposit that clings to the side of the tub instead of washing down the drain with all the rest. Wiping the ring zone right after every bath with a white nylon-backed sponge, or even a washcloth, while the water is draining out, is by far the easiest and best way to banish bathtub ring. If you let it accumulate and harden, you'll have to scrub harder or use chemicals. Cleaning the bathroom fixtures regularly with mild phosphoric acid solution will also keep rings under control.
If you haven't kept your ring guard up and there's a buildup as black as a skid mark on there, spray it down with heavy duty cleaner solution, give it a chance to penetrate and loosen the soil, then scrub it with a white nylon backed scrub pad. Finally, rinse and buff to a shine with a dry cloth. If your tub is old and worn or you or a previous owner were in the habit of using powdered abrasive cleansers on it, Dial-A-Maid Cleaning Service in Evanston, Il. 60201 says the tub ring will cling and be extra hard to remove. You will need to use extra elbow grease to get it out.
