Suggestion on cleaning powerheads

[ALang]

I read that people use vinegar to soak their powerheads to clean off the algae, etc. Here I have been scrubbing, scraping and cussing about doing it for years!
Questions: do you use vinegar full strength? Do you just put the whole PH into a bucket and just let it soak (how long, approx??)? Do you need a new bucket of vinegar for every PH or can it be used over and over again? And of course rinse everything thoroughly afterwards.
Thanks. Finally, an easier(?) way of cleaning PHs.
