I have a green cotton filter in the vrs and was wondering whats the best option, to clean or replace it with a standard filter? Also how do i clean and re oil it?

Theres a cleaning kit available from green direct or you can just use fairy.

take it out, wash it gently, rinse, dry thoroughly (i bakes mine in the oven on a very low temperature for 10 minutes to amke sure it was completely dry) then spray lightly with a new coat of oil, leave to dry, put back in the car.

alternatively just stick a standard one back in choice is yours.

if you go down the cleanign route i've got a bottle of the official green stuff i can let you have (i left my filter for so long between cleanings it rusted and broke up)
