I have a few Forrest saw blades and one of them started to get rust patches on it. I was told to use several rust removers, but had none on hand. I was also told to try a mixture of lemon and salt. No good. I then tried white vinegar. To my surprise it worked. Bt too good. It turned my blade to a steel bluish gray color. I thoroughly cleaned and dried it. Put on a good coat of wax and put it on the saw. Doesn't seem to have any problems yet. But what about long term? Outside of Boeshield and Evapo-rust, what else can be used effectively that will keep from discoloring and/or ruining the blade.
Thanks.
P.S. As a side note, the method I used originally took off the rust, but it left a stain where the rust was. That is why I used the vinegar.
