19 nia.. still quite young.
Anyway, try alcohol? You know those alcohol that nurses rub you
with before they give u a jab? Maybe your first aid box might have
that?
Else bring a small pail of water, lock your room and then take
off cover of bedsheet then dip those affected area bit by bit and
rub off.. then blow dry with fan. So long as u do not dip the whole
bedsheet in and only the area is soak with water and then wring
dry, should dry quite fast by blowing fan on it.
okay thanks
