I decided to take a new approach to cutting foliage today... with a cheap Musashi blade, of course. Bad news abound though; after cutting small bushes and saplings back, the blade was coated with sap. I cleaned most of it off, but there's one area that was slathered in it which has stained the blade a gray color. I'm thinking of ways to remove it now. Rubbing it extensively with a cloth proved fruitless, as did water. I was thinking of steel wool, but I'd like to think of other ways that don't involve grating away the steel. Ideas?  |

I usually clean my blade with rubbing alcohol before reapplying a new coat of mineral oil. Perhaps rubbing alcohol might remove the stain? If anyone knows if this is a really bad practice, let me know  . |

You could try Metalglow or Fritz ? they are polishing cream that you rub with cloth

Any abrasive you use will alter the blade's finish, seldom for the better. This includes polishing pastes (metalglo, flitz).
The best way to get sap off the blade is to not cut plants to begin with. This is the primary reason I personally try to dissuade folks from such.
Failing restraint (respect?) though, remove it asap with warm water and maybe some soap. Anything on there longer than a few minutes won't be coming off without taking metal with it.
Cutting live vegetation is a bad isea.

Luckily I used a cheap sword! |

I use spray bug and tar remover for cars. It takes a bit of rubbing but works.

The price of the sword is irrelevant. In fact, the cheaper the sword, the more dangerous to you, the user.
Just don't do it, eh? Is the concept really so difficult for so many?
At any rate, WD40 and the bug and tar remover are good suggestions, but be very careful as you buff. WD40 especially, being a lubricant and all. Slipping is not advised.

A good polish is also a determining factor in how easy it is cleaned
A rough polish
^^^^^^^^^^^^^^^^^^^^^^^^
Has many openings where minute amounts of dirt can deposit. It can be quite difficult to get it out, even with a cloth or water once the dirt hardens out.
A smoother polish
________________________________________
Has less openings for dirt to sette in, dirt will stay ontop and is easily wiped away.

I use some stuff called "goo gone". Works great and doesn't stain (so far).

Never tried on a sword, but I do know this to remove sap. |

I know there's been some good suggestions already, but I personally like to use either Rubbing Alcohol, or if something is really stubborn to get off then get a can of "Electric Motor Cleaner" spray from a local hobby shop. It's safe on most plastics and it works wonders on sticky things... I personally use it on my RC cars during maintenance. And all my cars are off-road so lots of random crap gets caked onto moving parts...  |

All of the above mentioned solvents and oils will work on various categories of dirt and grunge on a blade. The trouble comes when the type of dirt (sap) chemically attacks the steel. Once this happens it is no longer a case of trying to remove a coating of stuff, the steel has oxidised and the only way to get back to the shiny stuff is to abrade the blade and then its a full polish job to get every thing looking even  |

Basically, at this point, as guyc has said; you're looking at a whole new polish. Good luck with that. |

Repolishing a cheap katana is not to difficult with high grit sandpaper, I like to use my thumb pressure along the whole edge, but putting it onto a foam pad works well too.
