What is the best way to clean up balsa that has fuel on it???

Microsoft, there is a product that was mentioned here that you can buy at almost any retail store, I believe it's in powder form, sorry I can't remember the name of it, but if you do a search on fuel soaked balsa, it should show up. Hope this helps.

Use a product called K2R spot remover.
You can get it at Walmart.

Yea that's it, thanks for refreshing my memory.

K2R is sold under another name now. I am sorry, I don't remember it, but there are some threads with a picture of it here on RCU.

Here is the name of the thread:

K-2 Spot Remover has a new name

I did a search on "soaked balsa" and found it on the results. Sorry, should have done that before posting my answer.
