Is there an easy way to clean AC return grilles?
I have two AC return grilles that always look dirty due to the dust that is continuously drawn through them. We live on a dirt road, so that doesn't help either. The only way I can get them as clean as I'd like is to completely remove them and wash them down with a garden hose. Within a couple of days they need a good dusting again. Can anyone recommend a quicker, easier way to clean them?
