Organic stains-vinyl liner deep end

[swimin]

Hello!
Opened the pool up, brushed and vacuumed, balanced the water. I have staining around the drain in the deep end where worms and leaves sat through the winter. Any suggestions on how to lighten/remove the stains without hurting the vinyl liner?

Patience will fix it.

It just takes time and chlorine to get rid of organic stains. You don't have to do anything special. Any aggressive attempts might damage the liner.

We had crazy dark stains on our white steps when I opened from some leaves that got under the safety cover. Two days of regular chlorination (well, I did get it to SLAM level when we opened to be safe) and the stains are gone. Give it time.
