Burnt bathroom mirror light cover - any need to get electrician out re possible short circuit?

Good point by IC - the burnt debris on that shade appears to be more than what would be created by a spray of Viakal, so I wonder if what you are looking at is the indelicate fragrance known as 'scorched wipe'?

Really worth an attempt at cleaning - becoming progressively more aggressive - but worst case is that a replacement is required. For this, if you are lucky, you may find a second-hand item on eBay, as I suspect the shade on its own will not be available from the manufacturer or supplier (but always worth a shot). 

To search, you'd ideally need the actual make for this - I see near-equivalents, but measuring would be required to determine whether they are similar.

I'm not trying to defend the silly actions of your cleaner, but anyone not familiar with the significant heat generated by halogen capsules, in particular ones in such close proximity to its surrounding glass shade, would not expect to be 'scorched' by a simple wipe-over.

Good luck in finding a replacement shade. Should you manage this, and even if you don't, please do consider LED replacement bulbs - they are truly awesome. I replaced that size of capsule - G9? - with LED a good few months ago, and they are indistinguishable to the remaining halogens in the same fitting. But, the shades on mil's ceiling light were larger than these, so had more room.

You could just stick the shade in the dishwasher. Can't really make it any worse.

Out of curiosity who supplied the Viakal and other cleaning materials, yourself or the cleaner?

They asked me to supply the cleaning materials, specifying what to get. 

They haven't been the most careful of cleaners - there's a small chip on one of the bathroom tiles which they caused from dropping something presumably. 

There do appear to be very small "burn" marks on the bulb actually, which is no doubt explaining a bit of a smell when the bulb is on. I guess the bulb needs to be replaced anyway. 

Thanks for people's help.

The halogen 'bulb' is fine. Only the frosted shade needs replacing - if you can find one.

One thing to be aware of if you do go for LEDs is to check the driver output both in terms of ac / dc and min load.  I replaced my kitchen unit overhead lighting - which is a very similar design to OP's - with LED, total 60w halogen with 9w LED, but the driver min load was 20w so had to get a new driver for £5 - ran it for a while with 4 LEDs and 2 halogens.
