Clean a Sous Vide Immersion Circulator

In the Sous Vide Equipment Forum
I just purchased a used Immersion Circulator (Polyscience). According to the seller it was only used in water (not chemicals) but I want to err on the safe side and clean it thoroughly. Do you guys have any experience or suggestions on how to clean my new (used) circulator?

Thank you in advance,

There's a few different ways to clean an immersion circulator.

To remove the mineral buildup they suggest "Depending on use and water hardness, scale and mineral build-up may occur. Clean by filling a pot with a solution of vinegar and water and running the circulator for about 30 minutes."

I've also heard that using the CLR cleaner on it works great as well.

For de-contamination type cleaning they suggest using an bleach wash, then vinegar wash, then alcohol wash. One thing to remember is that if you bag your food before you put it into the water bath there probably isn't anything in the water that could make it through the plastic.

Here's a link to a video about generally cleaning an immersion circulator:

Sorry that it's mainly links and not a "here's how to do it" but there seems to be differing ideas on how to do it best and I figure you're better able to make up your mind for what you personally feel comfortable with. Hope this helps!

Thanks and happy sous viding!
Thank you very much. This is quite helpful.

What ratio of CLR to water should I use to clean my immersion circulator and for how long should I run it? I read it somewhere but I can't seem to find it. Thanks in advance.

I think I've seen a 10% solution of CLR, so 1 part CLR to 9 parts water. Though I would think the CLR would have directions on it and would be safe to follow those.
