PLA vs Starsan?

[matt_m]

Anyone have any experience with the long term effects of Starsan on PLA? Looking at options for a blowoff jar mount so this isn't something that would need to be sanitary but it would probably be in regular come in contact with Starsan and/or Starsan foam.

What's the mount made of? StarSan is slightly acidic, but not enough to have an effect on most materials.

PLA is one of the plastics used in 3D printing.
The pH of a standard Star San mix with DI or RO water will reach into the low 2s and will definitely eat certain materials, including some plastics (like Delrin)...

Cheers!

Sorry; I read your first message as "StarSan or PLA." I thought PLA was a new sanitizer.

You could always drop some PLA into a cup of StarSan and run an experiment.
