So I have some staining on the bottom of my fiberglass pool. Used some vitamin C tablets crushed up in a sock and it removes the stain easily. Read up on cleaning the pool with ascorbic acid (AA). Started shopping for deals on AA and read where back in the 1930s Dr. Albert Szent-Gyrogyi isolated AA out of red peppers. Later scientist decided to improve on mother nature and create AA in the lab mixing corn syrup with hydrochloric acid and voila ascorbic acid. At least that's what the interweb says:D. So got me thinking hydrochloric is much cheaper than ascorbic acid. I'm not a chemist and didn't stay at a Holiday Inn so reaching out to those more knowledgeable on this. Any thoughts?
 
Not sure how expensive vitamin C tablets are, but you can buy powdered ascorbic acid off eBay for about $10/lb. That's pure ascorbic acid, not mixed with sugar and such in vitamin C tablets.
 
Yep, kinda figured that. Just was hoping for a cheaper solution to AA. So the cheapest AA I found comes from China, surprise surprise. I guess since I'm not putting it in my body or am I (since it will be in the pool) but I'm sure it dissipates in time. All these acids are like cousins at a large family reunion, some good and some bad.

So I need to look for the words pure ascorbic. I guess it's all either medical or food grade? I was surprised some of the pool supply stores didn't carry it. I guess they have "other products" that contain AA with a little of this and a little of that they would sell me.
