Any suggestions on how to revitalise old reflectors

So I have some 8inch dominator's where aluminium reflectors have become dull and corroded in places. I tried a metal polish but it just made I worse.
I'd rather not purchase entirely new units as I can't find replacement internal reflectors.
So I'm thinking of using a spray paint or film just no idea what would be suitable.

Worth a try to find some Mother's aluminum polish and try again, IMO...WalFuck has it. I've used it on very oxidized/dull 60 year old aluminum and it looks like chrome now

Buy a package of a milar blanket very cheap. Cut a couple pieces and tape it over your reflectors. I do it on some reflectors I made and it works great. Good luck!!

Is this not plastic based? I'm running 1000w in air cooled reflectors

I use this stuff called CPL it's actually a gun cleaner but hubby buys it in big containers so i borrow some when i need it for any bare metal that I need to clean. If it's bad borrow someone's electric car buffer it'll clean aluminum up very quick.

Autosol, best alloy polish, use it to polish alloy on my car, Australia has it, any aluminium polish will work

Could you post a pic? Aluminum doesn't take to paint very well.

Depending on the severity I'd have to agree with DoctorDetroit. You may also be able to get away with using a scrubbing pad or sand paper made for aluminum. The beauty of aluminum is if you sand it down it'll form a natural layer to protect it from rust/corrosion as soon as the metal contacts oxygen.

Sun system has reflector wipes claiming it will "restore" without residue. It's cheap, worth a try I guess? New inserts would be best, maybe email hydrofarm(largest distributor)?

Last resort would be an acid wash.

Good luck.

I look at it this way. If I've ran my reflector long enough to degrade the aluminum then it's more than paid for itself and I'll buy a new one.
