What is the recommended % for atty soak? Have found 30-75% so far.
Thanks
Thanks
have not lost any myself yet, but have only been vaping a little over 3 months, have cleaned all 5 oh 1/2 dozen times each no problems yet.
As for any minuscule trace amount of the acid that just may be left after long rinse, followed by extended soak in large volume distilled water, then a steam clean well after 35 years of 2+ packs a day, decades sucking exhaust sharing the road with cages,
The remnant you speak of is not an acid residue, it's iron phosphate (a salt), known under the trade name as Parkerized steel. It's a layer of phosphated iron that's chemically bonded to the underlying "pure" iron in steel. It's not a residue of phosphoric acid, and is not readily water soluble (nor is it soluble in PG, VG or PGA). You ingest vastly more phosphoric acid in a Coke than what would be left in an atomizer after even the most rudimentary water rinsing.Drinking a mild solution of phosphoirc acid mixed with larger ingredients cold is not the same as inhaling the heated reminents into your lungs.Phosphoric acid is many times stronger heated. It leaves an acid residue. Try idpping stainless steel in it and allow it to dry. There you will see the grey film left on the test product. Then try to wash it off with runnunig water and let dry. you will see the film persists. On a coil that may have residue that has not been eliminated, the acid will soak in and the next time you vape could be unpleasant.
