Air fiter cleaning and oiling

[Maxbashing]

hi all,

i have just bought a Losi DBXL and i have heard the air filters often come over oiled. Anyone got suggestions for products for cleaning and oiling the filter. I have seen stuff in RC shopds butas this is a two stroke i am presuming i can probably pick up something cheaper on the hightreet.

For my nirto cars i have used washing up liquid to clean the filter but i wonder if this needs something more hardcore.
