I did the cleaning process again using isopropyl alcohol and so far is working a bit better I’m thinking the problem is my spring, my mod is an authentic mod and like someone mentioned can’t tell what make my spring to collapse in the first place just let me ask you something else as you mentioned the spring should have a smooth throw and I’m using superlube dielectric grease, since here in my country I was not able to find noalox which I read is good for conductivity but I will like know your opinion on that.
Thanks
The lube/protectiveness that's in those particular kinds of contact cleaners that don't completely evaporate, if apllied on screw threads of a mech mod, has a tendency to be broken down gradually due to micro-arcing, which isn't to be confused with arcing. After the lube (and/or so-called "protective" layer) breaks down, it speeds up corrosion instead of slows it down so you get an adverse effect, and, you simply don't want that happening on a mech.
The only valid reason to use the kind of contact cleaner product that removes oxidation buildup (e.g., Deoxit Gold) on a mech's screw threads is only after you have stored the parts unscrewed for a long period. This is because oxidation is caused by bare metal surfaces coming into contact with oxygen from the air, and, by screwing the parts together, air gets squeezed out so whatever oxidation still occurs from changing out the battery or switching atomizers gets polished away by friction from screwing the parts together and ends up at the edge of narrow spaces in which, due to machining tolerances and small imperfections in the smoothness of the polished metal surfaces, the surfaces don't touch, where oxidised metal dust sits until it gets removed through regular maintenance cleaning.
In the narrow spaces where the metal surfaces don't touch, only a thin layer of air remains present if parts are kept screwed together tight so oxidation in them is minimal as a result, and does not matter because there is no electric conductivity when the metal surfaces don't touch in these specific areas.
Further, frequent polishing of screw threads should not be required if corrosion is kept to a minimum by keeping screw threads constantly clean. Frequent polishing removes metal, thereby causing small areas in which the metal surfaces don't touch to grow bigger over time until finally the resulting performance degradation becomes noticeable. I hope this was helpful.
