I once heard ... but never tried it ... was that cat urine is really good at breaking down grease.
First, give your cat a couple of salty sardines to eat. They will force your cat to drink extra water. After that, pick your little kitty up and give them a gentle squeeze to facilitate the process. Sometimes it may help to put their paws in warm water. Word of advice, be sure you are aiming him/her in the right direction and towards what you want cleaned. After all, you don't want your cat whizzing on you.
With your cat's help, soak object really good. If you have more than one cat, great. Do this with two or three for easier cleaning. Just remember to aim the little critter the right way. You don't want to have an negligent discharge of cat piss. Let said cat whiz dry and you won't have a care in the world left for the grease.
Prior to the squeezing and whizzing process, you will need to set up a camera so we can all watch the video. Good luck!!
