BioRad recommends washing with methanol (4 bed volumes) and water. However, we found it insufficient to remove highly hydrophobic substances (e.g. pyrene derivatives). We use washing with hexane:isopropanol mixture (3:2, ~4-5 volumes) followed by washing with methanol or ethanol (~4-5 volumes) and water. The capacity seems to be completely restored.
