My two-sided wall heater 's vents are dirty and some have lost paint. They look terrible. For years I have been resolving to Do Something About It. I even bought a spray can appropriate for a heat-emitting device.
But I need to clean the vents before spraying over.
Somebody suggested I take down both vent covers and do it out in the yard. Not being very handy, I sorta balked. Still open to the idea faut de mieux, but would rather not have the hassle.
Any suggestions for cleaning in situ?
