cos it's in some a/b'd psudo.
Heard tale of some rust in some psudo. Just a few flecks but enough to fuck a birch in the ass. How might it (the rust) bee removed without another a/b? magnet? will charmin have the filterability if the psudo is dissolved in some dry isopropyl or methanol? :P
Rust does not carry through a properly performed A/B extraction. Do it again.
Why cant you just re-dissolve in alcohol & then fine filter? AFAIK rust is not soluble in alcohol.
