thanks for your answer, and me, answering to your question:I didn´t buy any acetone.a friend, painter, gave me around 1,5 litre for me removing some painting. The bottle he used to pour acetone is P.E plastic, which seems not to last too much storing acetone. I have finished removing painting and around 800ml acetone has not been used so I want to store it into a 100% safe bottle. So, my questions are:
1.If I use a glass bottle, with cap, and seal the borders with silicone: Will acetone vapors affect to silicone, or vapors alone are not enough for that?
2. Is HDPE safe?
