Acid wash or resurface?

[JohnnyPBC]

Hello,

I will be closing on my new home in a few weeks and I can see the pool has some issues. I was told at first that it was a saltwater pool but now it’s a mineral pool. I’m not sure if it’s worth trying to acid wash the pool to buy me a few years or invest in a resurfacing? Any help is much appreciated

Welcome to TFP.
It is hard to see in the pictures, but it would be wise to inspect the surface of the entire pool. If there is any soft spots or if the plaster is chipped or has pot holes in it. If so, the re-plaster may be best. An acid wash can help remove some of the stains but it can also damage the underlying plaster. It can actually increase the likelihood of more damage going forward.
See the article for some info

Why Acid Wash New Quartz Pool Finishes?

It is understood that muriatic acid can dissolve and etch a plaster surface. Therefore, why, after a plastering finisher works hard to achieve a smooth, hard, brand-new, hand-crafted, quartz pool-finish, would anyone immediately perform an “acid wash or acid bath” on that pool and that plaster...

Welcome to the forum!
One thing for sure -- it is direct evidence to NOT use mineral (metals) in your pool water!
Tough call. Best would be to ignore the stains, make sure the water is clean and sanitary by following TFPC, and save up for a replaster.
I suggest you read ABC's of Pool Water Chemistry.
