Cleaning metal heat registers? (baseboard type)
I realized recently that our the grilles in our baseboard type registers are *filthy* ... seems as if they've not been cleaned in decades, and have dust/dirt residue and other cr*p pretty well embedded into the grilles.
I'm wondering what the best technique is for deep cleaning the register grilles? The vents are metal & painted, and unscrew out of the register surround (see pic below for details).
I pulled one out and tried cleaning it by hand, but using sponge, soap and water only helps a little bit. Would appreciate any suggestions to get these truly clean? Alternatively, any ideas where I could get new, replacement vents?
