Here is a video made in December 2020 that seems to give a good selection of the Don'ts and Dos of Paint Brushes ...
https://www.youtube.com/watch?v=WCWd1TPHZOwOver the years, it seemed obvious not to use my primary paint brushes for washes (and the new contrasts, which I'm not using currently anyway), and texture paints, and my father taught me upfront about using different brushes for metalic paints. However, the whole video seemed worth watching anyway, even if only as reminders.
Towards the end it covers brush soap, cleaners, and restorers ... items I knew existed, yet probably need to add into my other good habits.
