Quoted from jboner1058:Placed the abs plastic posts in a ziplock bag with 6% peroxide. Then placed that bag in the sous vide water set to 125 degrees for 8 hours with UV light blasting it (stirring the bag up every hour or so to even out the light distribution. Then went back on the nylon parts for 4 hours at 160 degrees to brighten then up a bit without melting them
