Yellowing on white plastics

[westbrook215]

Opened my pool a week ago to some algae, nothing new.

this years opening was my first with my new liner.

noticed anything that is white has turned yellow, main drain cover, light bracket, stairs, skimmer faceplate.

I have a test kit but it’s hard to decipher pH level it’s pink but hard to tell the shade.

I have public water and never had this problem in the past. Scrubbing with a brush doesn’t make a difference and I have an area on the bottom corner near deep end that is yellowish.

Iron most likely. Take a vitamin C tablet and rub it on a spot. It should instantly turn white vitamin c is ascorbic acid. To get my stairs I just spot treat by putting a few tabs in a sock and then smashing them up with a hammer. Then just rub the sock on the stairs. Easier then the following article if you don’t have a lot of bad staining.

Vitamin c tabs crushed up in a sock like you said worked! So my question is did your staining come back?

I put algaecide in the fall last year could it have come from that?

I didn’t add water to my pool I just opened it 3 weeks ago. I don’t recall the steps being yellow.

You can do an ascorbic acid treatment to remove it all. I have trace iron in my city water as well.

Bought a culator pack will see how well that works.

Haha! Yes I will always deal with iron staining in the pool, at least a little bit. In my area the soil has so much iron in it that any area that has been cleared looks like the surface of Mars. We have red clay here so I just treat my stairs and my skimmer. My liner is only a few years old, if that starts looking bad I would try and treat it.
