Changing your alcohol (especially the clean wash) frequently is a big help, but that gets expensive if you aren't redistilling your solvent like we do.
The two big post-processing QA improvements we figured out that you can do right now, without having to upgrade your equipment significantly or increase your costs, are
1) Adding a quick "third rinse" with brand-new alcohol, just a quick rinse with a lab wash bottle when the parts are still dripping in the basket from the second-stage clean wash; and
2) Forcing alcohol through any internal cavities or holes under pressure, either a hard squeeze with the wash bottle, or with a bigass syringe (50/100ml is good) that you fill from the first-stage wash.
You can also get in implant etc holes with a brush and alcohol, but just blasting a syringe of alcohol through is very effective and thorough, and quick if you have the syringe ready to go. Adds maybe 10-15 seconds to post-processing for each batch, but you get far fewer rewashes, slightly-tacky parts, or rejected parts down the line, and you don't have to be so eagle-eyed looking for resin when you load parts into the UV box.
