I wouldn't mix it either. But if you drain , fill and bleed, I've never had an issue. You can tell by the color when all the old fluid has been bled out. Any minuscule fluid remaining has never caused a problem for me.

I agree, a thorough cleaning is not necessary. If it's of any concern to you. Bleed the system every couple years, at least a few pumps out the bottom.
