Mytime, I know exactly what you mean! When I used to go out to breakfast with my friend/colleague on Fridays (well, I still go, I just have iced tea now
) it was as sure as death and taxes that SOME portion of that egg would end up right between my.. uh.. "womanly curves". It drove me to distraction because I couldn't even sit back further because the tables in the booths are so close. I felt like Edith Ann from the old Saturday Night Live!
The best thing in the world I suggest for stains is a spray stain remover called Spot Shot. It's in an aerosol can with an orange lid. It is made for carpets, but it works a treat on clothing too. (My mom read a book called "The Queen of Clean" and she suggested it) I don't know what it has in it, but when I treat stains with it, you can literally SEE them disappear. I'd just give the mustard (or whatever) a good spray with that, leave it sit for 60 seconds, blot with a clean cloth and repeat until it's mostly gone. Then just throw it in the wash!
It's a miracle for me because one of my cats likes to gorge themselves on food and then get sick. (I just can't find out which one!) One look at that stain on champagne colored carpet and you would think there is NO way that's coming out. BUT - I've used that Spot Shot and nee a mark remains!
Good luck!
