Dc clear! It works great, is reusable and no nasty iso fumes

only thing is you really need to heat it up to get it working but that’s easily done in the microwave and when you do it works a treat. Then because it clumps resin together instead of dissolving it you can let it cool after use and then filter it and it’s ready to use again and again. I am paranoid about cleanliness so I scrub everything with fairy liquid and rinse thoroughly after using the hot dc clear too to be extra sure but apparently it’s completely non toxic anyway. Stuff comes up completely good as new it works so well. I think it’s better than iso to be honest because in iso the resin dissolves into the alcohol then a thin film of the dissolved resin and iso is left on the vape stem or whatever you have cleaned. With the dc clear it gets stuff really as good as new it’s very satisfying and above all for me no iso fumes or residue etc.
