Kano Laboratories' SiliKroil is the result of the blending of Kroil, which loosens, and dymethyl silcones, which lubricate. SiliKroil penetrates to one millionth inch spaces, dissolves rust and lubricates to loosen frozen metal parts and keep them moving. It can be used for frozen slides, bearings, gate valves, hinges, chains, locks, rollers or any place needed to loosen a frozen part and provide long-lasting, non-evaporating, silicone-enhanced lubrication, the company says. Silikroil is now available in seven sizes including a new economical 16.5 oz. King Size.
