I always use Jar to wash my PC components

By using an upper case "J", in "Jar", that suggests a proper name. So is "Jar" a product name? Or do you mean something like a
pickle jar filled with hot soapy water? If you mean a product named "Jar", got a link?
Google is of no hope here.
Frankly, as a certified electronics tech, I do not recommend "water" based products to clean circuit boards, including plain or soapy water - especially hot water. The PCB (printed circuit board) itself is made of several laminated layers of copper, substrates and solder masks. In an "
ideal" world once fully assembled, the boards are sealed in epoxy resins or polyurethane to make them water resistant (note I did not say waterproof!). Epoxy resins and polyurethanes also help keep those layers from separating should the PCB be exposed to water or even very high humidity.
But we don't live in an "
ideal" world!
PCBs are drilled with 100s of holes for component leads exposing the various PCB layers. Along the board edges, or when boards are repaired, or just during the manufacturing process, the various layers may be exposed. The epoxy resin or polyurethane protective covering may be damaged or incompletely applied during manufacture. And if water seeps in between the layers during cleaning (or Baptism by beer

), further damage (and possible separation, corrosion, etc.) may occur. Remember, water is "the"
universal solvent!
Also, many boards include micro-switches and adjustable or "variable" components. These are not water-tight devices. Not to mention there are many exposed contacts in connectors and headers where remaining residues may affect continuity, attract dust, or even promote corrosion.
So PLEASE! Do yourselves a favor and stick with products designed to clean electronics! As mentioned twice above now, use a quality
electrical contact cleaner. For stubborn spots, use an
acid brush to help the cleaner. These products contain no water. They evaporate completely and quickly. And they leave no residues behind. Cleaning electronics is what they were made for.

If CRC QD Electronic Cleaner is not available in your area, look for
WD-40 Specialist Electrical Contract Cleaner. It too is great stuff.
