Best way to clean a clear retainer - hints and tips please!

I have never thought to try Dawn...what a good suggestion!

Adding my suggestion, as I don’t think I saw it mentioned yet in the thread.

I’ve been wearing the same essix retainer for15+ years at this point, and I’m a huge advocate for daily rinsing (and brushing if needed), and a monthly(ish) diluted white distilled vinegar soak, followed by a good thorough brushing. I won’t say it’s 100% perfect after 15 years, but looks pretty darn close!
