I recently bought a cheap RDA from China. It has a strong plastic/metallic/strange smell/taste to it. I took out the coils and soaked it in water, but it didn't help. You can taste/smell it on the cap and deck without any coils/wick/firing. This has been a known problem for this particular RDA with some bad batches here and there. The machining is also pretty rough, so some residue may remain. I've heard soaking it in alcohol for up to 24 hrs or continuous blow torching could help. I don't have a very reliable blow torch, so I'd like to avoid that if possible. Also, the deck smells too, so no sense in ruining the o-rings and grommets. Also, I'm thinking boiling/baking the top cap first to see if that helps. Any suggestions on how to get rid of the taste/smell?
