Don't clean your gun with acetone. It is much too harsh and will damage plastic components like seals.
Use a general purpose lacquer thinner or specific gun wash (but not the recycled stuff). It is a much less aggressive solvent that won't damage your gun. Don't soak in it though, other than a minute or two for all metal parts like aircap and needle and fluid tip. If you have a plastic baffle like the Devilbiss, just wash in thinners and then rinse and dry immediately.
Always clean your gun immediately upon finishing spraying. Don't even delay it for that much needed fluid exchange or the ciggie you've been hanging for. I've done that, become distracted and come back to a gun in which the clear has set solid. It's definitely not a fun job to clean the gun then.
Don't forget to lubricate your gun after cleaning.
