I've used oven cleaner with very similar results. 60 seconds in the cleaner and a gentle rinse with soapy water and a tooth brush to get into the nooks and crannies.

if you want even better/easier to work results use Draino crystal.. I used to strip paintball guns and polish them up all the time using that method.

I wouldn't...

Not that the Chemicals will possibly effect the fit of the bearings in the grips or get into the bearings in the swash plate. (lets test the seals on the bearings to drano!)

Not that I don't like dull alum that is now susceptible to corrosion and will require polishing. (anodizing actually penetrates into the metal... so how is it removed without removing some of the base material... ...)

It will probably work fine but personally I just wouldn't do it.

But that's just me.

Have Fun!

Well, you can always get it anodized again... a different colour

ICON is on the right track. The anodizing is a corrosion protectant and also gives surface strength to the part. Why take it off if you aren't going to re-anodize it clear or another color?

Anodizing is a surface hardening process. I was told that anodizing a wing spar on an "real" experimental airplane would CUT IN HALF the rated "hours" of use of the spar! No corrosion though. And the spar would have to be replaced after 150,000 hours of use instead of 300,000 hours LOL, like you could fly that much in a lifetime!

Be real careful here... I just ruined all of my bling. I left it in too long and it ate into the threads. So much that the screws didn't fit any more. I was pissed. I just bought some parts that I've been waiting til I could spare the cash. I could only get the tired old blue. I threw in the other blue bits and pieces in. I don't know if I left it in too long or put too much drano in. There was a violent reaction. 45 seconds later and everything was black. I brushed it off with a tooth brush and everything had shrunk. I was able to salvage some things by tapping it a little larger and using larger screws. But duh, I hate that I have different sized screws. I'm a bit anal. Be careful.

I agree and a much slower and maybe safer bet is liquid drain cleaner. I've used it with the assurance that it doesn't have such an aggressive action. Best is a housebrand because they're cheaper and milder in action.

Anything steel that was attached, grub screws, bearings, is now rusted. I guess patience is not one of my stronger qualities.
