Loosen jammed screws and nuts in record time. The cold shock that forms at the time of spraying breaks up the rust on the surface, so that the active agent penetrates better even into the tightest fits. When loosening screws or nuts, the contained microceramic optimizes the coefficients of friction and thus the lubricating effect. The product also prevents the formation of corrosion and is neutral towards plastics, varnishes and metals.15
