[SSsssteamer]

Also used as an antifreeze has been salt water. A friend in Idaho bought a 1906 Winton that had salt water antifreeze left sitting in it for years. The salt water prevented freeze up but over the years of storage, it ate holes through the cylinder walls. Also used as an antifreeze has been straight kerosene. No-freeze windshield washer solvent can foam up in the cooling system and over heat it. I presently use RV antifreeze for our Stanley steamers for winter storage. Works well but like it seems it is a little hard to get a quick steam up for winter use while using the RV antifreeze.
