I had to trim the box hedges as they were getting a little unkempt. I knew I could do them at this time as they are the type that only need one trim a year, but will keep water on them. After the trim I wiped CorrosionX on the blades and there are a few stainless steel parts.
Here are the hedges,,,,done.
Just used my fingers and dipped them in my plastic two minute noodle cup which is where I have a small rag with CorrosionX.
Hit the four Stainless parts on this side, again just wiped it on with finger.
Turned it over and hit the same stainless parts on the backside.
Good as new. I bought these in about 2003 or 2004. Will have to add a full shot as they are really in exceptional condition, but I do the same every time I use them.
