So, have we found the magic solution for wfp here? 
it did seem to give a higher shine and i thought it soaked bird crap quicker,one thing it DEFINITLEY stops everything freezing,on the day we got some both of us were froze up (it was minus 4 at 10 in the morn) brush was solid pole hose solid ,i thawed them in shed got the iso ,added some to a barrel and went back out,worked a treat,brush stayed soft,pipes all fine
