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.

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.
