On a serious note
I have a stain on my car seat right between my legs as a result of some mayonnaise type crud spurting forth from a big mac, at least that's my story and I'm sticking to it and not being the worlds most elgeant eater it is believable. I've tried everything to get rid of it including various chemical products and steam cleaning. It goes away for a while then comes back again like the ghost of some unhappy cow/horse/other that transferred it's spirit to the sauce. Hopefully when you eat the stuff it passes straight through your gut. Any tips on removing McDonald's mayonnaise stains will be greatly appreciated.
Disclaimer: This was an unfortunate incident due to inexperience with McDonlads cuisine, I must have eaten their products no more than a handful of times.
