I decided to give it a clean to remove some finger marks and dust after I left the light in bits for a few day’s.
I used 50/50 isopropyl and water and now it has a yellow tint, so I then tried using some gentle car polish and then and then a slightly more aggresive compound with no change at all.
Anyone experience this before?
Thanks
How did you apply the isopropyl / water? Reflector coatings are very delicate.
Sounds like you have worn through the reflective coating.
Preferably, you don’t want to touch the reflector with anything at all.

Yea, never physically touch a reflector coating if you can avoid it, although protected aluminum (SiO) and rhodium PVD coatings can supposedly tolerate this as per MIL SPEC, not that budget lights have these coatings.
I just use plain warm water and dry with compressed air if I need to clean a reflector after re-machining or the like.
Yes. You should never ever touch the reflector with anything other than water and compressed air.
To remove the yellow look, you need to replace the reflector.
I didn’t want to be the one to say it! :-x
Sorry, about your reflector.
Sorry to say but I agree with the others. Time for a new reflector…
Fwiw I have found using my dishwasher works really well for cleaning reflectors, I just put the reflector in like it’s a drinking glass. Doesn’t appear to leave any residue and gets them crystal clear.
With just water or regular dishwasher detergent?
I just put in one of the Finish (brand) dishwasher tablets on a hot cycle. That brand specifically advertises that it doesn’t leave water marks on glasses and it seems to work pretty well on the reflector.
Wow, I would have thought a dishwasher would the the very last place to put a reflector. Very surprised they survive.
Isopropyl is bad fluid to clean reflectors, optics etc.
I use 50:50 mixture of ether and ethanol. Pure ≥99.8%.

I have cleaned high quality reflectors, Brynite, Fenix, Crelant, and Surefire with Dykem Die remover (a very strong alcohol) in a sonic cleaner, with excellent results, the cheap reflectors don’t fair as well. 
I put two Jax X6 reflectors in and both went well
This is very interesting, exactly what finish brand tablet are you using? did it remove the fingerprints and fogginess of the reflector completely?
Just a gentle wipe down with some tissue paper soaked in the isopropyl/water mix. It’s not as if I was rubbing it hard at all. The same happened with my Convoy X3.
Well that’s disappointing to say the least if I have ruined it, I just didn’t expect them to be that delicate.
What are the chances of getting a replacement reflector?
