should I use a sintentic or natural brush to clean electronic ?

[Mantra]

Hi

I want to clean a wonderful Pioneer A-88X
I had some canned air units , some contact cleaner dry and wet (in short i don't how translate but it does leave some oil for the pots "knobs" )
and some brushes

can i ask you 2 questions?
1) should i use some contact cleaner wet for the pots like volume , treble ,bass ?
i have read the contact cleaner dry will remove all the grease that let move the knobs very smooth

2) what kind of brush should i use to remove dust?
a sintentic or natural brush ?
just to remove some dust

thanks in advance

Re 1) Unless you already have scratchy or sticky pots, no.

Re 2) Use an anti-static brush, like these: https://uk.rs-online.com/web/c/esd-...g/esd-control-clean-room/anti-static-brushes/
Together with a bellows: https://www.amazon.de/-/en/Octopus-Compressed-Cleaning-Sensitive-Electronic/dp/B09YYX18XX

Instead of canned air, think about getting one of these:

I use that and it works great.

Just had some repairs on my computer and the tech used one of these. Clearly better than canned air. The keyboard action is much smoother.

Isn’t the issue with canned air that the expansion makes it cool down, leading to condensation.

Not an issue if you can keep the can close to level. The main issue is how little usable "air" you get out of a can and needing to buy more.

Here in Germany the pro's weapon of choice is "Teslanol Oszillin T6". It can be used both as a grease (on the shaft/bearing) and as a contact cleaner (for pot wiper and track). Use as little as possible, don't drown the pot/switch.
However, when the track (carbon, usually) of the pot is worn out, it cannot do any wonders and you will have to replace the pot.

As for the blowers, you can of course use whatever you like. Canned pressurized "air" is not my favorite. It's expensive, and it contains propellant gas which usually is inflammable, it has a cooling effect and sometimes spits out liquid droplets. Motorized blowers are too bulky and often don't have much adjustment range. Manual bellows works best for me.

The issue with those blowers is that they are basically a smaller version of a leaf blower and sometimes the air stream can be a bit too powerful. I wish that the one that I had came with a slower speed. It has two speeds but even on low it is a bit much. So I usually end up just using canned air. But it does come in handy at times. Good for getting all of the dust out of a power supply in a computer.

True. It does have more than enough power.

It's not complicated.

Use either a shop air compressor with a moisture trap, a blower attachment and a paintbrush, or a shop style vac on blow. Do it all outside.

what kind of brush should i use to remove dust?

Use a boar bristle pastry brush. Example:

You can probably find one in a local shop or market for a few Euros. The best ones have the metal ferrule that holds the bristles. Wash with dish detergent before and after use. After washing and before using, wring out or flick out the water from the bristles and then squeeze it in a dishtowel until it feels just slightly damp to the touch. Picks up the dust with no chance of static damage.
