I recently cleaned my 510 atty with a 50/50 solution of bottled water and glycerin. I used a syringe on the battery end to push the solution through. I blew out the excess liquid. I then set them cart side down to dry for like 4 or 5 hours. The problem I encountered is when I use these attys now I get a weird burnt taste. Did I do something wrong? Is this normal? Can it be fixed? Is the atty burnt out? please help.
