It's not stain, it's lime scale/calcium build up, hard water deposits. We have hard well water so bought a good water softener system. It's helped a lot, but through the years, there's just been a gradual build up. It's my own fault, I was using a 'daily shower spray' and not actually cleaning the shower for months. It looked clean, but just not shiny clean. I was the only one using this shower. In the last year, my husband has been using it...and always acts surprised when I bitch about him not using the shower spray. Erg. Standard excuse is that he just didn't think he had to use it after every shower.Will 3% peroxide lift the hard water stain?
Maybe kitchen, laundry and general? Do you use a standard cleaner in the bathroom and elsewhere?I'll leave it up to you. I'm brain fried. Perhaps, kitchen, bath, and other??? You've got some good ideas, so just run with it.
