Wish ya were closer I have something that'll fix ya hard water! Or has mine anyway!! Limonene ⋆ EnviroSpec I use it on everything... cleans windows and your vehicle paint better than any cleaner I've used!! After it's mixed I can WILL burn your skin 1st degree if left on it trust me I've had bad burns from it! But it's animal safe plant safe won't kill ya grass! If it's left to dry on something then you will never get it off unless you put more limeonine on the spots it dried to especially windows it will leave a white cloudiness if it dries on paint or windows! Grainger, tsc, lowes may have something similar but envirospec has their own formula to my understanding and the shit works, streamline pressure washing llc has been using it 16 years now!
