About 6 weeks ago I wrapped some strips of an old dishtowel around a couple of rusty brake shoes and rust flakes. You can read all about it here. 
Two of the three had some great orange color all the way through. The third…not so much. I’m thinking that one didn’t get much of the vinegar I splashed into the bag on it therefore it didn’t rust as much.
This is how they looked before rinsing. I let them hang dry in the garage so it would be easier to brush off the rusty bits before doing the final rinse in the house. Too cold in the garage yet for that.
Again two of the three are nice. I’ll likely only use bits of the mostly white piece. Or perhaps ask for a “new” hunk of metal from Mr. G so I can re-rust it.
Very nicely done!
OK, I’m only FIVE days late seeing this post. I SO apologize, but that AB has taken over my life. Now that it’s nearly finished, I can breathe again.
I adore your rusted fabric. I actually like the white one because it looks like something you would paint, with the circles and lines. It really looks YOU.
You DID use baking soda in your rinse, didn’t you? I sure hope so. I’m so glad you shared this, even though it took me nearly a week to see it! I always love it when you rust (fabric that is).
