Forgive me if I have missed this somewhere in my searching.
With that said, what products have any of you successfully used to remove those white, scaly, hard water stains from pool equipment, water lines that refuse to clean, bathtubs, showers, tile, whatever.
Things like CLR and "Some dude's magic this/that.." come to mind. There are products by ZEP and just about everyone out there.
I have various hard water challenges around here.
One example is: glasses left out for days on end that are repeatedly used for drinking water will build up a white scale that's impossible to completely get rid of.
I have let undilute 20 baume MA soak in them with only some impact. The same on our fiberglass showers. Even back when they had brand spankin' shiny new gel coat 15 years ago, it started right away and couldn't get it off.
I have some used pool equipment I bought that has the same junk on it... I think. Looks like it.
Any ideas what actually works on these minerals that are left behind when the water evaporates, ones that seem to be attached like they're bonded and one with the surface?
Maybe I'll have to resort to a soda blaster... but I'd like to avoid that expense for the time being.
Any advice, recommendations would be great!! Please do try to state what you have used it on.
