I ve actually struggled with this issue going on 2 years now.
Green stain vinyl pool liner.
In order to treat your vinyl liner stains you first have to identify if it s an organic stain or a chemical stain.
Over a period of time pool liners tend to accumulate different types of stains.
Green or green brown pool stains organic usually caused by decomposed leaves twigs algae or other plant life.
However you cannot treat vinyl liners with acid wash so you may be out of luck.
Having unsightly stains on your vinyl pool liner however can quickly make your otherwise perfect looking pool look anything but appealing to swimmers in your household.
To identify the type of pool stain you re dealing with match it s color s to one of the descriptions below.
The center of the pool has about a 2 3 foot.
Vinyl pool liners are not made for harsh and abrasive cleaning agents.
Pool liners have to be handled with great care when cleaning stains off of them or you can damage and discolor the pool liner.
And vinyl liner pools they present a particular challenge.
Cleaning up a swampy green pool is no walk in the park it can take hard work balancing cleaning and filtering the water to return a dark green pool to swimming condition.
My liner is completely covered with stains that look like algae on the floor and walls.
I have an inground pool with vinyl liner 18 x 36.
The stain is not completely solid and seems to be in the pattern of the water flow in my round pool.
