I have a recipe that will remove most stains and stuff like that which I don't mind sharing.
Four parts camel jizz
One part white wine vinegar
Two parts yak shit
1 gram of toejam
2 grams bellybutton fluff
2 pubes from your wifes patch
Combine the ingredients in a blnder and give them a whizz, take the mixture and heat through until just before boiling point. Seive the mix through the gussett of a tramps knickers and beat softly so as not to knock all the air out of the mix until you get stiff peaks, allow to cool and put into a jar.
You can dab a tissue into this and it'll remove anything. You can also use this to enhance the length of your old chap by applying just before going to bed at night. I cannot guarantee the results though, its only what i've heard. (cough)
