Word of warning:
I was doing a maintenance wash this morning and a shower started just as I was doing the final hosing down. I drove the car into the garage to dry it off and used my leaf blower to get rid of the worst of the water. A few minutes later when the shower stopped, I drove the car back outside to dry the remaining water off with towels. Aaargh! Everything was covered in fine grey dust! My garage has an unsealed concrete floor and I can only assume that the blower was lifting dust off the floor and blowing it all over the car. Fortunately, it all seemed to lift off easily as I did the pat-dry outside.
So, note to self, do all blow drying outside! Especially as that was the first maintenance wash after I'd done a full decon, polish, seal and wax.
