One possibility is to wash the material three times with 1-butanol. That should remove the phenol, and them wash again with 96 ethanol twice to remove the 1-butanol and air dry the ethanol, after centrifugation steps. I hope this helps.

The phenolic content can be removed by washing the sample with the isoamyl alcohol 3-4 times followed by 70-90 % of ethyl alcohol. Remove the ethanol by evaporation in air or in speed vacuum concentrator.
