Beginner Question about dirty IPA disposale

Hi Guys,

so i recently got a used Elegoo Mars2 Pro and Anycubic Wash & Cure 2 and a few resin bottles for about 50€.

I know about all the PPE and its going well. My question is: I would usually put the dirty IPA in a container outside in the sun (there isnt much but hey). But i recently read about IPA offgassing and potentialy causing explosions , which makes sense since its flammable.

I read somewhere here that some people but dirty IPA in a glass container. Shake it and then cure it with the curing station for 5-6 mins (repeat that about 4-5 times) and then store it in a dark place (probablay not fully sealed lid so it can release pressure). After then take the good ipa and fully cure the resin goo and just toss it since its cured.

Would that be a good way? Its just im kind of scared leaving it on my balcony unattended for weeks for the sun to do its job since it is again..highly flammable.
