I find safety caps very frustrating in the workshop as arthritis takes over my hands. However, I have the tools to ease the problem. Squeeze and turn tops can be defeated by using side cutting pliers on the lugs. Press and turn tops have a double cap. Use a screwdriver to lever off the outer cap, a sharp knife will trim the plastic projections, then hammer the lid back on. Only a little pressure is now required. Mensshedders always label their bottles and keep them out of reach of children.
