Silikroil penetrates to one-millionth in. spaces to break bond of rust and provide lubrication at first molecular level, freeing the frozen metal part. Dimethyl silicones provide extra long-lasting lubrication to keep parts moving. Silicone also enhances its water displacement qualities and improves its performance as cutting oil. Lubricant is designed for use on frozen bearings, slides, gate valves, hinges, and chains.
