Whats the best stuff to use to clean an airfilter??

While doing some under bonnet bits on my car over the weekend I put my hand on the airfilter which turned my hand black

So defo needs an urgent cleaning really.

So which stuff then

 

its called AIR FILTER CLEANER!!!!!

 

depends what filter

dont just ask a question and only give us half the info!

warm soapy water can often do the trick, then a re oil ie, K&N re oiler, if its a K&N filter.

 

ive heard that you can stick them in the dishwasher on cold, meant to come out brand new

 

Yer it's a K&N.

SO just soak it in a bucket of warm soapy water and re-oil after.

I take it halfords sell the oil??

 

Ive got some piper cross oil which is in a spray can. I would think most car mod places would have it
