Removing oil soaking from balsa
What is the best method to remove oil from oil soaked wood. I am recovering a project and want to get a dry enough surface for the monokote to stick well. Any ideas and/or products that will do the job will be appreciated.

Corn meal, heat, alcohol.
Spread corn meal on the fuel soaked wood to get the worst of it off. Apply heat, (appx 180 to 200 deg is PLENTY) it drives more oil out.
For problem areas, swab with rubbing alcohol and then use more corn meal and heat.
REpeat as needed...
You can NEVER get all the oil out, and some oil damage is irreversible. [img]i/expressions/face-icon-small-sad.gif[/img] But you can get enough out that glue will stick again. Balsa that has started to essentially dissolve... cut out and replace. Ply that is delaminating must be replaced. (Its VERY hard to get the oil out of aircraft ply... easier to replace it 90% of the time)

Thanx!
I don't need to replace wood at this point. I used heat and paper towels to absorb what came out. I then used denatured alcohol with a clean paper towel after each wipe. The mono now sticks well. I am going to really fuel proof where the covering meets the firewall. I am also going to use a tuned oipe on this model to keep that nasty exhaust well behind the affected area. I only wish I would have taken better precautions against the oil seapeage several years ago when I originally built the model!

I use Rx2 Spot Lifter. It's designed to remove from grease ect. from clothing. It is sprayed on & turns to a white powder when dry & really does a good job of removing oil from balsa. Just brush of the powder & the oil is removed. It can be dificult to find, I found it at Ace Hardware. Give it a try. Good luck.

Try bicarbonate (baking soda). Sprinkle liberally.... will cake... break it up with finger, vacuum.... Do not use for cooking after!
