Stainfree is an all natural citric acid product that removes metal staining on pool liners and finishes.
Citric acid for swimming pools.
I cover using bulk ascorbic acid and also using natural chemistry stain free which is citric acid.
Stainfree is ideal for treating staining on all pool surfaces and is compatible with all sanitizing systems.
Ascorbic acid treatment this is how you use a large amount of ascorbic acid to treat staining in your entire pool.
This is a good treatment if your pool has a lot of staining and the spot cleaning is not an option.
Be sure ph is low and after cleaning return return water to normal chemical levels.
Depending on the pool size and stain size another method besides treating the whole pool with citric acid is to treat the stain directly that is fill a literal sock with citric acid and put it directly on the stain initially with circulation off.

For citric acid for pools.
Citric acid is a gentler stain remover than muriatic acid another form of acid used to remove stains and resurface swimming pool interiors.
After 12 hours brush and circulate.
It does not harm a pool to have such a thin layer removed it simply clears away the stain.
