Hi Rob, I use a mix of water and dawn dishwashing soap 1/3 soap or more and 2/3 water, I soak the bowl in the soap water for 2-6 hrs or more depending on the wood, this will help a lot.
I have even used mineral oil by spraying a light coat on the bowl let it soak in for 4 or 5 min. and then do your carving, you can spray on more mineral oil if needed, you want it so soak in about 1/2 inch or a bit less. Aloha.
