Thank you so much for this thread. I have an igo-l and was having this problem and not knowing why or what it was... I also was just recoiling it everytime it got too gunked up.. going through wire and silica.. this time i just dry burned it while blowing on it allot, to get out all the leftover juice (this step didnt really clean anything so if you stop here dont expect results), i turned on my foset to the warmest setting and let it heat up real good and put my igo-l under it, sideways, without the mod attached ofcourse.. i left it under the water for a bit while rubbing on the coils gently with my fingers (it couldnt hurt to leave it on there as long as you want... the silica gets fully absorbed with water within the first second..), then I dried it off with paper towels best i could, wiping off some more black resin on the way, then i took a blow dryer and dried it out the rest of the way to get more h2o out.. stuck it back on my titan and started dry burning it while blowing.. after the crackling stops you know theres not much water left, so you can stop blowing on it and just burst fire it to where the coils get red, keep burst firing and dont be afraid to really pump that ....... until you see your silica turning back to original color... I did this allot and it looked like a nearly new coil assembly!! next i took a sharp knife and scraped off the last remaining bit of black on the coil, now the coil looks more grey than anything... I hope thats not oxidation from me applying h2o then overheating.. but i just dripped up some kel pop from vixen vapors, and the FLAVOR IS BACK! this puppy is tasting better than it did when i first coiled it! (i dont torch my silica, waiting on my blazer big shot gt8000 to ship..)
