简介

Metals used in circuits can react with oxygen. It's a common and natural reaction and can cause connection problems, but the process is reversible with deoxidizing sprays which can improve the sound quality of your amplifier.

    • Carefully wipe the circuit board and its components to remove any dust.

    • Failing to remove any dust before applying DeoxIT may cause the dust to get trapped on the components, increasing the risk of overheating.

    • Lightly spray the circuit board with DeoxIT.

    • Take care to evenly coat the circuit board with DeoxIT. Excess liquid will dry slowly. If power is reapplied before it has completely dried, it can cause short-circuits and damage to the device.

As an electronic repair technician I would never advise spraying deoxit on a circuit board or removing dust with a papertowel. May I suggest using a can of compressed air to remove any dust inside the unit and focusing the use of contact cleaner on potentiometers, input/output jacks, sockets/plugs etc. Cleaning the top of the circuit board will do little to nothing to improve the performance or sound of your amplifier as you will simply be cleaning the top side of components that are physically soldered to pads on the other side of the PCB.
