Some of the outside windows on my house are beyond regular cleaning. It looks like they are covered with hard water scale.
Thought since you guys are in the know you might be able to help me.

What type of pad and compound would you recommend I try with my Flex?

Here a few ideas to go with: Trying claying the glass, maybe going with Steel Wool #0000. You can try some vinegar on a small area to see if it helps lossen them up. One other way is thru glass pohishing with one of our kits for glass polishing:
Professional Glass Polishing Kits we carry or you can use any polish you have with a LC white pad with your Flex and if you don't see any improvement then move up to a orange pad but remember to be very careful going that route.

White vinegar works for me, Had problem with hard water spots but White vinegar took them off. try small area first

Thanks guys. Will give the vinegar a try before trying the pads and compounds.

I use our DP Glass Restorer on my glass at home by hand, works well and removes water spotting.

White vinegar
2 minutes with a soaked mircofiber cloth and 15 years of hard water scale just disappeared. Even scrapping it with a razor in the past wouldnt remove it.
Pays to ask stupid questions

I clayed some of our windows and it worked so well the Boss/Wife now likes them all done.
