[Topso]

I have some small 5ml bottle is plastic and i have used them before and i was wondering how to clean them so theres no residue of the e-liquid that was there before and ofc so they are clean from anything else.

Wash in soap and hot water. Perhaps boil them if you think the plastic could take it.
