For chains and small components we put them in jars with the white spirit first and aceton second and shake.

You need to clean the chain really well before the first wax, so that bare metal is exposed for the wax bond. The rest of the stuff you’re talking about (chain ring, cassette, etc) isn’t getting waxed and doesn’t really matter (although now is a fine time to give them a relatively deep clean). The wax lubricates motion among the plates/pins/rollers of the chain, and that’s it.

There is no relative motion to lubricate between the chain components and the sprockets - each time a roller comes into contact with a sprocket for a trip around the gear, it stays fixed in place and the pin rotates inside the roller. This design leads to chain wear (easy and relatively cheap to replace) instead of cassette and chain ring wear (expensive).

Zero Friction Cycling is the place to go to read about waxing details. Here’s their chain prep guide.

Silca now makes a product that promises to make the initial chain cleaning trivially easy, but you need to heat it all to 125°C to work (instead of only 75°C for normal waxing), so to use it you pretty much also need their expensive crock pot with its precise temperature control (normal crock pots don’t get that hot).

How old is your cassette? I ask because another option is to just replace it, if it's getting up there in miles or kilometers. But some cassettes are ludicrously expensive, so it's not always a good option.

I've used Moto floss to clean between the gears of cassettes. It's like soft thick rope. Works really well. From Amazon, for example.

This is the hardest part of switching to wax.

Hot water and dawn dish soap. Use one of those green scrubbing pads. Then use alcohol or spirits to get the remainder off.

A powerful pressure washer? That worked for me when cleaning
