If you have a hedge trimmer then Stihl SuperClean is a must. This resign solvent cleans and lubricates in one. The graphite and lubricating mineral oil-based cleaner is perfect for all your cutting tools. The actual purpose of this spray is to prevent the resign from sticking to the blades and gluing them together inhibiting their cutting ability and also protecting them against rust.
This tool is especially critical for battery tools as the electric motor sometimes does not have the strength to overpower the glue if the tool is put away in the shed without being sprayed first. This lubricant is also say to use on cutting attachments without affecting the plants unlike some other workshop lubes such as WD-40 which can brown off the hedges for example.
