after cleaning rp, SwiL notices small particles of fiber in rp after drying it out. i guess small strands from the cardboard off the strikerplate breaking down. how can he get this out?

boil the RP in muriatic acid. it will eat the paper right up. It will completely smell up the whole place too though. the vapors are so bad you will have to leave the room. just letting you know. after the hcl boil (about 5 minutes or less) filter out teh RP and then wash it in a lot of water.

thanx....would i get this same reaction if i add hcl to the tone in the beginning?

You should probably do it the way that was suggested.
