I use molasses quite a lot and this is the result, lovely shiny clean bits.
I use a mixture of 10 to 1 molasses to water, that is diluted enough.
I wire brush each item after rinsing it off and then it is ready for priming after a wipe over with a wax and grease remover.
Lynx manual carrier before immersion.
The finished item ready for painting after repairing it.
DO not put any die-cast items into the solution or you will end up with that a bit of mush.
Any oil or grease will stop the process at that particular point, but will continue to work on the rest of the item.
