Query: Mommy, it burns

So you put this wick in your old kerosene heater and the kerosene heater works like new. Only concern is the burning sensation the wick tends to complain about. Hopefully your wick will test negative for STDs, but if not, most STDs can't stand the heat the wick deals with, so you should be fine. As always, I am not a doctor, but I did buy and enjoy this wick.
