I’m not sure if this is the right forum for this. I need to find a cleaner to remove pitch and whatever else is on my saw blades. What do you use and where do buy it. My blades have some build up on them and I need to clean them. Any help will be appreciated. Thanks in advance.

I mainly use whatever household degreaser is in the closet….409, LA’s Totally Awesome, Greased Lightnin, Fantastic, Goo Gone, etc. They work great….I use the cover from a 5 gallon pail, spray on both sides, then scrub briefly with a brass brush, rinse and dry. If the pitch is stubborn, you can let it sit for a while longer before scrubbing, and/or repeat the process. Freud recommends a kerosene soak for stubborn pitch. The blade specific cleaners work well too, but are more expensive than household cleaners…..Boeshield Blade n Bit, Trend, CMT, are just a few of the brands.

Simple Green, cleaner found under the sink at my place.
Inexpensive, effective for numerous uses, even saw blades.
Lid from a five gallon bucket, add Simple Green, wait half an hour, scrub off with a kitchen scrubber.
DON’T FORGET to return the scrubber to the kitchen.

Oven cleaner. Dollar store variety. Let sits for an hour. Rinse off.

I’ve used both Simple Green Pro HD (like $12 for a gallon of concentrate from the orange box) and Rockler Pitch and Resin Remover (I think $15). The Simple Green is enough cleaner to last forever, at least the way I use it. You can also reuse the Rockler stuff. I’ve reused the same bottle four times so far and it works just as well now as the first time.

I’ve heard that regular Simple Green can weaken the bond between carbide teeth and the steel blade, but I don’t remember the source or how reliable it was. That’s why I ended up with the purple stuff (the Pro HD) not the green stuff.

Either way, you soak the blade in some kind of flat-bottomed container and then brush off the crap. I use a $1 pack of copper/brass bristled brushes that I got from Harbor Freight. It gets all the gunk off. If something is stubborn, soak it longer or brush it harder.

I will say that it’s incredibly easy to cut yourself while trying to hold a blade to brush it, so wear some decent work gloves while handling them.

It’s kind of amazing how fast crap builds up on your blades when cutting soft and/or resin-y woods. I had to clean my blade twice during my workbench build from all the crap the spruce left on there.

I have heard that oven cleaner will attack the bond between the carbide tips and the blade and could cause a tip to fly off the blade.

There was a previous discussion of this topic, where I first heard of CMT. Works great! Just spray it on your blade, wait awhile, and wipe it off. Leaves a protective coating on your blade. I got mine from Amazon.

I use the purple “simple green”. I’ve got a 5 gallon bucket that I keep the lid on. I just drop the blade in there (after threading a cable tie with a washer on it through the center hole) and leave it for a couple of days if I don’t need the blade right away. Recently, however, I left a 15-year-old Freude blade in for 3 weeks and all the writing came off the blade. So, don’t leave it over a few days.

The 5-gal bucket is a fairly snug fit for a 10” blade so if you don’t want to spend 10 minutes trying to pick the blade up out of the bottom of the bucket, think ahead and leave something through the hole so you can lift it out easily. A 12” blade will not fit.

I hope this thread helps but this has been covered many times. The search function on this site works well and brings up many hits.

Oven cleaner will not damage the braze material or carbide under normal use. If you left it on their for weeks, who knows. I use one cleaner and it works well but it can cause skin burns so use it safely.

Thank you to all who responded to my request for a blade cleaner. I will try your suggestions. I have some decent blades that get gummed up with use. I tried carb & jet cleaner but it evaporates too fast and does not stay long enough to soften the crap.
Thanks much

I use Bit-n-blade. Spray it on let it sit for 30 sec scrub with a toothbrush taped to the bottle and wipe it off. Works great.

Simple Green for me as well. It works great and I just rinse off the blade with warm water and dry.
It takes of all the gunk that collects on the blades.

Castrol “Super Clean”

just spray on and brush/rinse and you have a clean blade in less than a minute.
