Rear screen cleaning

Hi all,

My rear screen has a build up of crud on the heater elements.

I'm guessing the hard water here has lead to chalky deposits around them when the heater is on, but what's best to clean clean it without damage to the thin wires? I have two of the elements failed already, and don't want to do any more damage, but I'm looking out through a rear screen that's a row of white stripes at the moment.
 
Which Im listening to on a very old MiniDisc player that I found in a box of outdated gadgets! Ive just got it working. I have about twenty MDs with faded labels to rediscover...
 
Over here we get products named CLR (calcium lime rust remover) and LimeAway - both are to dissolve lime scale/calcium buildup. These are safe for glass and plastic and commonly used to de-scale shower heads, clean the carafe on your cofee maker, clean the dishwasher/clothes washer etc. This sort of stuff should work on you window without harm but I recommend you protect your carpets/upholstery with plastic as some bleaching/staining might occur. Just wipe on and let it "eat" the buildup before wiping it off. Probably need a few applications to get it all. I would be careful about commercial/industrial grade products as these might be too strong.
 
For a natural alternative, try lemon juice. The citric acid should break down the chalky deposits with ease.

And wipe along the wires rather than across them as this is less likely to damage them.

 
Thanks, wasn't sure what those products would do to the heater!

At least the replies got sensible halfway down. [:D][:D]
 
Considering your question wasn't too sensible-count yourself lucky-anyway why are you looking out through the rear window?-personally I'd concentrate on looking through the front one.[:D]
 
Turned out to be an amusing thread Paul.
I just use glass cleaner but quite like the lemon idea. Could also use it in a G&T after!
Like you I have a few elements that don't work. Wonder if there are any tips for re instating them.
 
I've seen a conductive paint for sale before now but the results always look like my 7 year old nails after she puts nail varnish on. I imagine that with a bit of careful masking and application that you could get better results though. The same would probably be true for the rear screen elements too [:D]
 
I think Halfrauds sell it-it's expensive as it contains silver but as |Dave says,careful pre-cleaning with alcohol,careful masking & careful application should give a satisfactory result.
Anyway,Dave what's this about YOUR 7 year old nails?[;)]
