Disconnect all cables and open connectors, and remove shields to gain complete entry beneath the circuit board. Place your circuit board in an appropriately sized vessel with enough 90% or larger isopropyl alcohol to submerge it after removing any exterior know-how. If you are unable to search out such a high concentration of isopropyl alcohol at a neighborhood drug store or pharmacist, using deionized or distilled water as a slower drying different is enough. Once it’s reached the desired temperature, turn it off, then place the circuit board inside. Leave it there for around three hours to completely dry any moisture left over by your cleaning process.
