Well, I decided to undertake a general cleaning of some of my more
forgotten Yixing.
My question is what to use for the grease/oil cutting, and if anyone
has any tricks or suggestions that I am unaware of. They have just
been soaking in hot water for a couple hours so far, and I tried a
gentle wiping with a towel but it isn't doing it.

Successful degreasing needs a good organic solvent. I've not tried
this on hallowed tea pots but it works on other delicate items. Vodka
- as strong as you can find - with a couple of drops of industrial
detergent per 100ml. Over here we still can get a perfume free
industrial detergent named 'Teepol' - it leaves no aroma or residue
and gives the vodka a cutting edge. Don't smoke while using this
mixture!!
