==Ultrasonic cleaner setup==
The ultrasonic cleaner should be filled with distilled water only, never tap water! The reason for this is tap water contains mineral impurities which can leave a conductive residue on the board, potentially creating further issues. If you are out of distilled water, ask a manager about purchasing some from a local pharmacy or grocery. If you would like to test a source of water before using it on a target board, you can first test it on a cheap piece of electronics, such as a portable calculator. The liquid we put in is a mixture of cleaning fluid (Branson EC) and distilled water.[[File:How to clean a board ultrasonic 1.jpeg|thumb|upright=0.5|right|alt=An ultrasonic cleaner|Ultrasonic cleaner]]The concentration should be approximately 3{{--}}5% by volume, so for each gallon of water poured into the ultrasonic cleaner, 4{{--}}6{{nbsp}}fl{{nbsp}}oz of Branson EC should be added. In metric, this is about 30{{nbsp}}mL per liter of water. Usually we put in approximately 1.8 gallons (6.8 liters) of water, and add 180{{nbsp}}mL of Branson EC. The easiest way to do this is fill up the ultrasonic cleaner “to the lip” with distilled water and slowly add Branson as the water heats up.[[File:How to clean a board ultrasonic fill line.jpeg|thumb|upright=0.75|right|alt=Diagram showing the lip in an ultrasonic cleaner|Ultrasonic cleaner lip]]
The solution should be heated to 140{{nbsp}}{{F}} (60{{nbsp}}{{C}}) prior to use.
