Has anybody got a good trick for blowing out condensers , espeacially on self contained units, where the dust is contained instead of blowing all over the kitchen or where ever you are? I use co2 and a wet towel over the back of the condenser but still it doesnt do an adequate job of containg the dust. A vacuume don't work either.Who out there has a good way. Also thanks to all for the help on the freezer. we are gaining, got er down and holding 8'.
