Some of you folks are probably doing this already, but I have not seen it mentioned. I use my pressure washer about 4 times a year. Early on, I found that when I went to use the machine the tips were clogged and the quick connects were hard to use and I would have to play with them to get them to work. Now when I get done with it and put it away, I spray WD-40 on and through the tips, I spray the quick connect fittings and work them. This will solve your clogging problems.
