So I just bought some squares of Japanese cotton off amazon by a brand name called master of clouds. I have never used anything but prebuilt coil heads and I just tried to use this cotton to rewick my cubis rba. I followed a step by step video and did everything right. Washed hands thoroughly before handling cotton. So I go to use it and it has a really bad taste almost like sour milk earthy taste I saturated the cotton first and everything. Is this normal I never have experienced this taste.
