Use brake cleaner to get out the diesel or else it will slip forever.

much easier and better off to replace clutch. diesel is very hard to get off of a clutch disc, because it's so porus

Hi, unfortunately the usual answer is that it will never 'clean itself'. The oil in the porous material used for the lining will hold there until you change it. Each time it slips it will glaze the friction plate more and more until it will let you down completely. Best thing to do (if it is still fairly driveable) is to save the money until you can afford the new plate and get it changed as soon as possible. Some cluches (though not many nowadays) are adjustable and tightening the spring tension can improve the grip, but even that will at best be only temporary. Sorry, but you've just learned an expensive lesson...that grease, oils or diesel and clutches do not mix. Good luck with making it last until you can spare the time (and the cash) to get it repaired. Cheers, BobSpain

Hi In a nutshell mate, you need to change the clutch. The diesel will degrade the clutch friction material. Sorry, but thats the top and bottom of it! Best regards Geordie

If diesel got to the clutch so can degreasents , pour some over the area leave over night then wash down well with water , heat should do thev rest , that is if the clutch is in good condition in the first place, and be a little carfull with some degreasents they can be inflamerble
