I guess the spray bin of the paint is one of the hard to dispose of.
Generally, you can’t toss it as the other non-burnable garbage.
Because it’s extremely flammable the same as the oil.
You must definitely not approach it beside a fire or burnable things.
You can use a coagulant for paint and get to solidify it, and then you’ll throw it away as well.
But this way takes a lot of time.
When you piled many spray bins of paint and you want to get rid of them, please let us know without hesitation.
