Cleaning optically coated glass.
Posted: Mon 05 Sep, 2011 9:03 pm
What do you use?
For me it was always just tap water and a PEL microfibre glass cloth - that is when I had to clean it at all because out-of-the-box, if you're lucky, you won't have to clean it at all, but sometimes you're not lucky and most times with offcuts you're not lucky either.
I've had nightmares - see a tiny speck, wipe it, cloth makes a streak that doesn't evaporate, wipe that, make 3 more, wipe them, make 20 more and then realise I was doing the wrong side of the lite anyway and then go and do all that on the other side. So, deep breath, clean both sides all over - hold the lite over a black surface for inspection and .... AAAAAAAAAARRRGGHHHHHHHHH !!!
Lines that look like scratches, blotches, 'cloudy' areas .... I've tossed many a lite and cut a new one from a full sheet.
The worst situation is when you've got something that requires a rebate spacer, you get the glass spotless (or think you have), drop it in the frame, fix the spacers and then notice a sneaky, miniscule little mark ..... end up with something you can hardly see through!!
A situation a bit like this .....

Well, today I was in that rebate spacer situation and I decided, after about an hour between two of us, especially seeing as we had no full sheets of posh glass left in stock, that this PITA glass had to go - not going to offer it any more - too much aggro.
But then I saw a kitchen towel roll and remebered someone on The Grumble saying they used paper towels - totally dismissed it - if a crease in a nice soft microfibre cloth could make a scratch ....... ?
Nothing to lose - grabbed a handful, wetted it slightly - cleaned - got a new handful, dried ..................... EUREKA!! Spotless.
Cloths may be fine if they are new or freshly laundered, but I think maybe even after just one use they can have body oils in them and I'm sure that's what's been giving me so much grief - the kitchen roll will always be virgin and if the glass coatings are tough enough ...?
The glass in question today was Nielsen's 'Clearcolour plus UV' (Same product as Wessex/Glass & Mirror's 'GM Museum' made by Flabeg) and Artglass - which cleans easier with a cloth anyway (but still not 'easily') can also be cleaned with kitchen roll paper - have not tried TruVue yet.
Apols if this is a 'DUH'! - if so just enjoy the funny Father Ted clip.
