Hi all,
I have a steel BBQ which I am looking to derust using phosphoric acid. The acid is very runny and the BBQ far too big to dip it into a container of acid. I was wondering what the best method of "soaking" the BBQ in the acid so it would remove the rust. Some thoughts I had were.
- put kitchen roll soaked in the acid on the surface
- somehow thicken it (e.g. cornflour or something)
- continually scrub it with a brush soaked in it
Anyone have any ideas / thoughts?
thanks
Lee.
