Citric acid works quickly to remove copper stains from pool and spa surfaces.  This copper stain remover is a quick dissolving powder which reduces the copper off the walls of your swimming pool. Once you use citric acid copper stain remover, you need to use Mega Maintain Sequestering Agent and a CuLator Ultra 4.0 to suspend the metals and then eliminate the metals so the stains don’t return.

    Citric acid worked wonders for my pool surface stains! I have been dealing with copper staining for months now and could never figure out why the stains kept coming back. After using the citric acid to remove the stains from the surface I also used the sequestering agent to sequester the metals, and the CuLator Ultra 4.0 to eliminate the metals from the water and the stains have not returned! Thank you CuLator for answering all of my questions and helping me through this process! These guys really care about helping people fix problems!

    This acid is best on my copper stains. But I ended up needing two bags. I had more copper than I thought because my heater dumped a bunch of metal into my pool because my pH went below 7. This product works.
