What can I clean RO storage containers with?

[pugbreath13]

My RO/DI water comes out at 0 TDS but after sitting in my storage containers for a day it is in the 30's. I use deltangs and they are about 5 years old. Can I clean them with something or should I just replace them?

A deltang?

USPlastics calls them Fort-Paks, my LFS's call them deltangs. It's the standard water jug you see for sale at most LFSs.

I probably wouldn't generally do anything, but a rinse with warm soapy water and a lot of clean water after that, followed by vinegar rinse (using straight vinegar)) may be a good way to remove certain organics that may be on the plastic surface. :)

I do not believe they use any plasticizers with polyethylene, but there may be certain surface contaminants from the manufacturing process.

I always use vinegar with no problems
