How to clean a MH reflector??

[Pike614]

I have 4 Lumenbrite MH reflectors. They have been over my tank (open top) for a couple years, I am noticing splashed stains on the interior reflective surface. This is 95% reflective aluminum I think....wondering how to remove the salt stains? I tried water, and the stains are calcified on....
anyone have a trick to getting them back to their mirror polish?
Thanks!

DI in a spray bottle works as good as anything. Way better then tap. Could remove them and spray with vinegar as well.

They are not going to come back 100% and I wouldn't be concerned about that.

White vinegar and water in a spray bottle.

If you are saying it is calcified in, a bit of vinegar will help loosen it. I had to clean my MH fixture when i bought it cause it was used.
