Tree climber

I just renise it and run fresh water through it and then hang it on a nail by the spray nossel so all the water runs back down the hose.this also keeps the hose stright.
been doing it this way for years with no problem.still have the same one for 5 or 6 years now.
I have one for posions for bugsand one for weed killers and brush spray.try to never use the same one for both. some of the weed killers just want wash out.
