Yesterday I got my Harbor Freight Parts Cleaner ($99) a day earlier than expected. Tonight I assembled this thing and it was very user friendly in doing so. The thing sits pretty in the barn's shop area, but no, I have not tried to use it yet. Right now, it is too cold out there and I am afraid I will freeze everything since the thing only allows water soluble solvents to be used. What is it that most of you are using in the winter months? I do have a heater in my barn, but that only will happen when I am out in the barn. What do you all think? Any recommendations on what's best to use in this cheap Chinese made product? I do have two gallons of Simple Green out there,...should I use that? Again,..what about freezing?
