Question: I have a gunite pool that has some iron staining on the bottom.
What do I need to clean it ?
What do I need to clean it ?
Iron can usually be removed with an ascorbic acid based product like Natural Chemistry’s StainFree, and then the water treated to remove the iron with a sequestering agent like the FerriTabs we sell (if you have a sand filter), or there are some alternative methods with different filter types.
Or, muratic acid on the area will often take care of it as well. You can either try to pour some through the vacuum hose to get it to the area, or a drain and clean (as long as the pool is not painted) should work as well.
If you have some photos you’d like to send over of your pool, the stain and equipment, we’d be happy to take a closer look.
