thanks.
Be incredibly careful with compressed "air." Lots of people wind up depositing the propellant on the things they spray, and you'll never get that stuff out of / off the reflector.
thanks your advise first!
send to SF, it means send to the headquarters ? or contact local agency first ?
i guess i lost the receipt a long time~, is it work?
The propellant is not diflouroethane, usually it is tetraflouroethane with a mixture of a few other chemicals (primarily HCFCs and some other stuff) after this stuff evaporates from spraying a surface, it does leave some slight discoloration, but it does truly flash evaporate and freeze what ever it contacts.
Best advice has already been given: Leave It.
If you must clean it you can flood it and wash it out with alcohol. Use 91-100% IPA. Anything less has too much water content and will be hard to get dry. This of course applies only to heads with glass windows and not plastic. Canned air can leave residue and more particulate matter than you started with.
