Check out this window. I have had lots of success removing hard water with a microfiber pad and a little abrasive compound like bar keepers or rain x. This job calls for phosphoric acid. The glass is really bad and may need to be resealed once hard water is removed. You guys ever seen any thing like it

Thanks for the tip. Any suggestions on sealing product? And do you think phosphoric acid will do the trick here? Kind of nervous cause this is a serious hard water stain
