Soaking - Citric Acid or Vinegar?

[Timrpn]

Just wondering what the consensus is out there on when soaking your equipment? Do you use Citric Acid or Vinegar?

Citric acid is the correct answer, vinegar can destroy pumps.

Fwiw,
I have suspected for some time that polyvinyl acetate based adhesives may be used on some pumps. If so, cleaning those pumps in a vinegar solution (acetic acid) may possibly contribute to hydrolysis of the adhesives. Especially at an elevated temperature. If that happens, it could cause a premature failure.

Citric acid is a safer acid to use for this purpose.
