In reply to tcb:
I've Cleaned my jkts down many times using Nikwax Downwash
Either lightly inside and out or by hand or in washing machine myself
Always worked very well for me. Personally I have managed to keep my jkts In
Good clean condition mostly so a light wipe down with Techwash has mostly
Done the job and that's with a Neutrino ,Crux Magma and a Rab Batura
