Kanger top tank leaking issues

Bought a top tank last week. I was using the 0.5 OCC pre made coil. When i bought it the dude in the shop wicked it properly and it was fine.

Time to fill up. Took the top off and filled to the top. After i put the lid on i notice my hands covered in <a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice. Its pissing out of the air slot.

Cleaned it up and it was ok.

Over the weekend ive been trying out the RBA deck. Exactly the same issue. Ive done a google and found a couple of solutions, which, so far have stopped it leaking!

Ultrasonic cleaners

Is there any benefit to owning one. Are they a multi tool for <a href="http://www.vapininthecape.com/eliquid_c_7.html”>vapers?
If they are what's a good model.

I <a href="http://www.vapininthecape.com/eliquid_c_7.html”>vape on heavy duty kanthal coils and currently clean them off with a metal brush every three days or so.
By heavy duty coil I am talking stapled claptons and the like.

Would a cleaner be better or would it not touch the clag?

I understand people steep their <a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice in cleaners as well.
Other benefits are just keeping my atty's nice and shiny.
