Hi All,
Yes that post of yours deviosi is a great thread and certainly explains it pretty much to anyone wanting to start a bath up for a project that's going to take a bit of time.
One very important thing to take care with is not to do reels as this process subjects the item to what we call Hydrogen Embrittlement which will make the steel much harder on the surface and as such if you want to do a reel this way you will need to place it in an oven for around 3 hours at 180 degrees C. This will stress relieve the steel and return it back to it's previous state prior to putting in the bath.
Regardless this is a great way of stripping very harsh rust.
Another thing to note is the more Washing Soda you put into the bath the more conductive the solution is and as such the quicker it will work.
I certainly overdosed mine and the results were amazing and in a much shorter time frame to, ..........and definitely much cheaper than blasting everything.
Cheers,
BB.
