|Monster use||Will not be used by monsters.|
A can of grease can be applied to grease any item. This protects items from rust and corrosion, and protects the player from grabbing attacks. A mind flayer can not attach its tentacles to a greased helmet, either.
A greased item may slip when you attempt to throw it, with the result that it falls to the ground or goes flying in a random direction. As long as you don't intend to throw the item, greasing it is harmless. Feel free to grease your melee weapon, boots, or any other item you want to protect. A greased weapon has no additional protection from a whip's disarm attack.
The layer of grease is not permanent: each time it protects you there is a 50% chance that it will wear off.   On your next turn, you can apply your can of grease again to re-grease the item. Until that turn you will remain vulnerable, which can be a problem when fighting fast monsters.
If a greased piece of armor is cursed, there is only a 2/3 chance that it will protect you from grabbing or mind-sucking attacks.
Grease is also useful for containers. A greased container will protect its contents from water damage. However, the water damage has a chance of dissolving the grease, at which point you must re-grease the container if you still want the protection. Oilskin sacks have such protection permanently.
A greased spellbook, scroll, or potion will be protected from blanking and dilution as long as the grease remains intact. Scrolls probably aren't worth a charge, but if you are wishing, you might as well order them greased.
When you are fumbling, cursed cans and non-cursed cans will only work 50% of the time. The other 50% of the time they will slip to the ground, consuming a charge. If you successfully use a cursed can, your hands will be made slippery. This does not happen with non-cursed cans, even when you are fumbling. You can use a towel to wipe your hands clean. If you want to grease your hands for some reason, you can do so with a non-cursed can by choosing "-" when prompted to choose something to apply it to.
