How to clean WD40 off of bare iron brake discs ?

[Fast Eddie]

What’s the best way to clean bare grey iron discs that have been WD40’d ?

Does WD40 soak into the pores of iron? Or does it just sit on the surface?

Will scrubbing with brake cleaning solvent suffice?

Or should I put them in the dishwasher? Boil them in a saucepan? Or some other ingenious method ??

WD40 is mostly solvent, and damn little oil. I use it to clean oil, chain lube, etc.


Then there was this one time at the Bikini Bike Wash in Daytona where the stripper used spray wax on my front rotors....

I didn't stop her.
I figured the sintered bronze pads would carry me through.

That reminds me of when i ground a disc for a commando owner a few years ago, I sprayed it with a rust preventative immediately after grinding (the water based coolant causes discs to rust before your eyes) This rust preventative was akin to Waxoyl. The silly sod just bolted the disc on without cleaning it and then complained his brake didn't work! Needless to say i left him with a flea in his ear with a few choice words about his workmanship!

You can place the whiffle ball on a plastic T for them.... but the slack jaw doofuses still need to swing the plastic bat.
