Presto Cold Shock Spray is a highly effective aid for loosening rusted or pressed connections e.g. screws, nuts, bolts, crankshafts. Special ingredients create a short-term "cold shock" (-50°C) on the rusted workpiece, which causes shrinkage. Also to avoid thermal damage during soldering work. Or to cool components in shrink connections such as bearing seats.
