I have just started doing some detailing part time out of my garage and it's going very well. So far as much work as i can handle part time. My upcoming problem is since i work out of my garage and don't want to go mobile or get a seperate location, how do i continue this winter when it to cold to do exterior wash. i guess that would be under 40 degrees. Am i sol until spring or maybe offer interiors only. I have heard of the waterless washes, but it seams if the car is very dirty at all, thaat may not be a good option. any suggestions would be appreciated
