I put together this pressure washing tip to be used for cleaning out carboys and demijohns. It works the tits for anyone who’s interested. It essentially shots the pressurized water at a 90 degree angle from the gun. It blasts all the grim from the side walls of the glass with ease. I have a video but I can’t seem to figure out how to post it to this thread. Anyway, you should be able to tell from the photo how I pieced it together.
