The only reason I shy away from WD-40 is that when it dries (which takes weeks), it leaves a hard varnish like film. This film prevents rust, but it may also cause the blades to stick together over the winter. I remember when a sewing machine serviceman told me not to use WD-40 on the close moving parts on a sewing machine, and not use it for a while. He said he used to spray this on new machines before giving them to the customer. Some machines, that were not used for a while, came back completely bound up with this thin film of varnish. I like to spray WD-40 on tools without close moving parts, for rust protection. That application works great for me. Thanks for your response. Charles Ranheim

PWD from KleenFlo works very well for your application. They use PTFE which I believe is a teflon base. NAPA, PepBoys or another automotive jobber should have it.

I agree with canguy. Some of those Stihl chemicals work good but are way over priced. Find something else that works well. A spray lube is better then WD-40. WD cleans really good but doesn't leave a very good lube, it is more of a water diaplacement [WD] then anything else. The teflon addative tends to stick to the metal pretty good and may just be the ticket. Regardless if you need to use while operating use it when done and flush out the resin before putting away.

I've seen many commercial guys who loosen up the blades to keep them from sticking, they never lube and clean. They end up with a huge amount of resin build up, add the loose blade setting and I can only imagine the crummy finished jobs they do.

Has anyone tried "Fluid Film". I heard about this, but there are no dealers near me that carry it. Charles Ranheim

Have not tried it.

Just came across this post.

I recenty purchased a Sthil hedge trimmer and have been looking for the Sthil brand of resin remover. Couldn't find anyone who carried it, but Parks Brothers in Prague is ordering it for me.

The hedge trimmer instruction booklet says to always clean the dust and dirt off the machine, but not to use any grease solvents for this purpose, i.e., WD-40.

There may be other good products of resin removers. Don't know. WD 40 is to remove grease, but you are needing to remove resin.

Wouldn't use WD 40 on my sewing machine ether or my garage door opener rollers. I lubricate with sewing machine oil.
Happy trimming!!!!

I had been squirting 5W-20 oil on my hedge trimmer blades in an attempt to keep them from gumming up. It worked fairly well. This last time I tried spraying Sea Foam on the blades. It did a much better job, and was easy to apply. I just sprayed a light coating every half hour or when it appeared the cutting surfaces looked dry. I also have better luck trimming early in the morning when the bushes are wet. It seems to leave less sap on the cutters.
