Containers safe to use for 3 part

[SeeFu]

Are these containers safe to use for 3 part?

Those seem to be PET. They wont hold up in the long run to high PH like in Kalk. Might be ok for 2 part tho.

Use HDPE.

Could probably use vinegar bottles - they're HDPE. Just get them new and dump out the vinegar... rinse and you're good to go.

i like these containers cause of the large opening. makes it so easy to dump the 3 part into the container.

That’s what I do. It’s cheaper to buy the bottles with vinegar then buying them empty lol.

I’d personally avoid the alk part in PET.
