Blitz Sonic Power Air Filter Cleaning

[griffin dai]

Ive just replaced my old Blitz filter with a new ITG foam one. What's the best way to clean the blitz one before I sell it? I've got some of the lightly oil spray stuff from ITG but not sure if that's just for foam filters?

Looks like the blitz one has a metallic gauze to it?

Cheers, Dave
