Ascorbic Acid is a fast way to remove rust stains,  iron stains and cobalt stains from swimming pool and spa surfaces.  Our rust and stain remover is made from food grade product.  It is a gentle acid which only removes stains in your pool.  Brushing will not remove metal stains from a pool surface, you must use Ascorbic Acid Metal Stain Remover.  You must start with your pool water below a chlorine level of 1 ppm for best results.  After you use the stain remover, you should use Mega Maintain sequestering agent to hold the metals in solution and then use a CuLator 1.0 or a CuLator Ultra 4.0 to eliminate the metals from the water so the pool stains will not return.

    I couldn’t believe how fast this product worked on my steps. It took the brown ugly stains off my steps on contact. I have a fiberglass pool and I tried this with the culator 1.0 to get rid of my problem. I’m very pleased. Thank you.
