Heavy metal shutters for veranda doors - best way to clean them?
We inherited 2 metal shutters (electrically controlled) for the veranda doors from the previous owner...two of the rare things that actually work... However they do make a lot of noise (which no doubt I neighbours don't appreciate...even if they bother us with their howling dogs.) As the previous owner wasn't particularly houseproud, I'm wondering how to clean them and also if there's a way of making them less noisy? As I'll be heading back this weekend I don't want to create more work but would like to find a way to clean them.. Needless to say there's probably 20 years of dust/sand which the previous owner never bothered to clean!! Any advice gratefully accepted! thanks
