Used container okay for aquarium water use?

[archerf40]

Hi I'm Taylor from the UK

I am in the process of setting up my clear seal tank for marine
I have found a shop that will sell me the saltwater by the gallon and I need to transport it home. My dad has loads of used 25l containers that I could use but they have previously been used for TFR (Traffic film remover).
Would it be okay to use these containers (obviously washing them out THOROUGHLY) as it would save me hassle and money, would you use them?
Thanks in advance

Taylor

If you're confident you can remove every trace of TFR, then I see no reason not to use them..

What exactly goes into TFM? Does it come with hazard/COSHH forms so you know how it might be harmful etc?

Okay then
I think TFR is just a car detergent and is slightly alkaline, not too sure though.
