Rust removal, better than evaporust and 10x cheaper..

I found a video describing this very idea- making a "gel" using corn starch- looks like it works pretty well- I am going to give it a try.
Helpful as I'm working on removing rust and paint from old Singer sewing machine cast iron legs to use for a table. I was going to sand blast them but might try this. Thanks

Corn starch works great..i have been using it with lye to strip paint off of some rims. just make sure to mix the cornstarch in cold water before it hits anything hot or it is instant lumps
I tried the gel thickening trick, did not have good results. Brushed heavily on a rusty floor pan, covered with plastic, and after 2 days the heavily rusted areas are still there. It did remove minor surface rust tho.
I believe it needs to be completely submerged in the un-thickened solution for it to work. I have been throwing heavily rusted small parts in a bucket of it and it works great that way.

Works good on small containers of fasteners too
