I was wondering this myself. I’ve used WC diluted 1:1 as a deacon with good results. Seems to me that the WC is still the better buy since you can use it full strength for wheels and cut it 1:1 for decon. This would make it much more economical than the new Iron Remover since a diluted WC is basically $30 a gallon as opposed to $50 a gallon for the Iron Remover.
