How do you get stains out of plaster?

[mshumack]

Do I buy a bottle of Vitamin C from the grocery store (for human consumption) or are you talking about something sold at pool stores?

You can just use vitamin C you get at the drug store. If you need to do a stain treatment you can buy ascorbic acid (that is what vitamin C is) in bulk - here is a link:

Let me know if you have any more questions, I am glad to help.
