      Eradicate Stains From Pool Finishes Naturally and Effectively

      Attack stains on your pool’s finish without the use of harsh chemicals. Take a safe, natural and dynamic approach to stain removal with Stainfree from Natural Chemistry. Treat stains on vinyl pool liners and fiberglass surfaces, using this safe chemical alternative.

      This citrus based, environmentally friendly cleaner will remove a variety of metal stains, and when used with Natural Chemistry's Metalfree delivers the ultimate one-two punch to go head-to-head with stains. This ascorbic acid cleaner is similar to infusing your pool’s surface with the power of Vitamin C, and unlike many other types of stain removers, Stainfree doesn’t leave behind residual phosphates, making it the premier stain fighter. To use Stainfree, ensure your chemical levels are properly balanced, and then add one pound per 10,000 gallons of water. With your filtration system on, sprinkle the product evenly along the surface of your pool. Wait an hour, add Metalfree to your pool’s surface and test water 24 hours later. Balance water chemistry if needed.

      Rated 5 out of 5 by from Great Product I've used this product in the past with great results. It removes any stains overnight but make certain your chlorine levels are low as instructed prior to use. Highly recommended to backwash the following day and to shock the pool afterwards.

      Rated 5 out of 5 by from Great Product Our entire pool was covered in a dull gray "dust film" that could not be brushed or vacuumed away. This did the trick. I didn't need to follow the instructions on the container precisely; just waited until chlorine level was low, sprinkled product around the pool and ran pumps all day and night. Then vacuumed the entire pool and backwashed. Added metal free. The water was slightly cloudy for a few days but after shocking with chlorine the pool and water could not look better. Highly recommended.
