• If the nozzles have scale buildup or under sized openings, soak the nozzles for an hour in a solution of 50-70 grams per liter of ammonium bifluoride. (Be sure to get proper safety training for this solution.) Spent titanium etching solution will also work.
• Rinse the nozzles thoroughly and recheck.
