ok, me again!

right so, i cant let a load of hard water spots get me! ive come too far to quit!
so instead of crying about spots i need to get doing something about them
and jeff brimble, you need to get in on this mate, for your benefit and mine!
so i need advice on how to rid the glass from this spotting disease

ive got some MDR but i think that might be a bit harsh to start off with so i recon im gonna see how much spotting i can get rid of with normal trad gear and a blade! would this work?
by the way, should i use only the sharp edge of my scraper for glass and the dull edge for plasic frames?
what would be the first port of call for hard water removal in your opinions?
thanks, look forward to hearing all your advice. once ive restored all the glass with spots i will keep a close eye on them using wfp in the future and get a technique good enought to not cuase them again, if at all possible!
