i think this is the first time i have seen super clean on u-tube since one lonely farmer tried their product out. IMO-hard to beat hot water pressure washer.
IMO. Right for the guy without a hot pressure washer good product. Now short of sandblasting a steam cleaner is my choice for cleaning tractor cast iron greasy parts a good steam cleaner not only will it clean old iron down to the hot dam you turn the part over and it will clean that side down to bare metal, they will peel paint and leave you with nothing but cast iron. Ready to dry and shoot it with primer.
