Looking at the video, the piece wasn't THAT dirty -and he had to shoot it so close and take a long time for a sq inch. Coulda spent 15 seconds with a wire wheel.
My results were the same. I went thru a box of Arm+ Hammer in about a minute. And not much to show for it except a lotta dust.
Its not strong enough to de-rust steel.
Good to know. Although a wire wheel leaves a different finish, it is effective.
Ill build one either way because even if I cant use it for rust I am curious to try it on anodized aluminum. The article says it will leave the anodizing which would be great for cleaning motorcycle hubs without unlacing the wheel etc.
I am skeptical of the idea of recapturing the soda because from what l have read the media fragments on contact, so it would just become so fine that it will do nothing but create dust. Who knows maybe you could use it a few times.
Hopefully I will have it rigged up today. I want to experiment on my nasty looking window frames. I also read that it doesn't harm glass or rubber. If I can make it work without wasting tons of soda I will be happy. Ill post results soon.
