Does 'pure' water do a better job than mains/tap water?

Or is it just a waste of 'pure' water?

Thanks

Yes. Without a shadow of doubt. It's the same property of the water to dissolve minerals and organic (e.g. bird poo) matter that works on windows works equally well on upvc and even painted surfaces.

Ordinary water and you need copious amounts and to scrub and scrub. 000 water and you only need a fairly gentle flow and to agitate quite gently.

I agree with wally however i would always use tap water (if i can) to get rid of most of the dirt and then go over with purified water otherwise you will in my opinion waste to much of your own water.

i would use tap water for this type of work , i dont think i would go over with pure afterwards .
