I tried the Woolite and brushed method. This removed lots of grime, leaving the water a sooty black.
After drying... I happen to be using some Fast Orange hand cleaner, when I had a new thought........... Smeared a coat of it on both sides, stuck it in a Zip Lock to soak, brushed and rinsed it a hour later, more grimey dirt washed out, but still the rust stains.

Been thinking about the spray CLR.... but wife says NO.

Thoughts?
