Refinishing Saw Blades

Post by tgamel »

I purchased a set of three SS saw blades, that had quite a bit of minor rust on them for $11.43, shipping was free on Ebay. The first thing I noticed when they arrived was that although they had some minor surface rust, the blades were nice and sharp. So I soaked them in Simple Green to remove any sap or build up, and thanks to many posts I have seen here on the forums, I soaked them overnight in Evaporust.

All the rust came off really easy and I took a small scotch pad to some small darker black stubborn spots. After rinsing and drying, I sprayed them with a light coat of WD40 to keep them from rusting in the future. The blades have a slight light grey color to them now, not shiny. Should I place these on their arbors and buff them with a little JPW to try and bring back the shine? For some reason I thought the blades would be well...bright and shiny after the evaporust treatment. If anyone has any other tips about how to clean blades or if I did anything wrong I would appreciate the advice.

I do not care about the slight grey tint of the blades as they seem to cut wood without any problems. I have just never used Evaporust and did not know if there was anything else I needed to do to protect the blades in the future...Thanks

I believe this is carbon deposits and much of it can be removed with a paper towel when the item is still wet and just out of the Evaporust bath. But Evaporust will darken the metal. I have not succeeded in getting Evaporust treated metal back to its original shiny color. I will be watching this thread to see if anyone else has had better success.

Since I have an electrolysis setup all the time, I would go that route.

I have tried evaporust in the past, but with a shallow immersion that I inadvertently let 'evaporate'. The blade acquired a black oxide appearing finish.

IIWY, I would now apply JPW and move on!;)

What? If I soak my blades in coffee I just gave up that coffee. Surely you don't expect me to drink it after soaking the blades!

I had read of the evaporating evaporust comment from a previous post, made sure I used a 5 gallon bucket with lid to keep that from happening. Not sure but it may have actually been one of yours post, so thanks for the warning on that one :) . As far as the grey discoloring goes, I can live with that as long as the blades cut well :) . I was Mainly interested if there was a better way to protect them from further rusting than a light coating of WD40. Obviously not leaving them in a damp environment or stacking them on top of each other would help (kind of looks like previous owner did).

Yea unfortunately, that did not work for me, even using a green scotch bright pad for light buffing of a few stubborn dark (black/grey) areas removed a large majority of the carbon (if that is what it is) but they still retained that almost dark brushed aluminum grey discolorization.
