I’m often amazed at how poorly cleaners work. There has got to be at least one expensive cleaner for every item in the world. Most of them do not work very well. Today I changed the blade on my table saw and tried to clean the old blade with one of those fancy blade cleaners. The fancy expensive cleaner ( names will not be used to protect the guilty ) I used does not seem to work worth a dam. So tonight while fixing my dinner I noticed the Bar Keepers Friend ( Dirt Cheap Stuff by the way ) under the sink. Its a very very mild abrasive for Cleaning Stainless Steel kitchen appliances. I decided to give it a try on my old blade, and it seems to work magic on the old blade, turning the old blade to new like some god more powerful then all of the many gods which have been worshiped here on earth for the past godzillion years ( Yes that includes you Al Qaeda as well ) .

Does anybody have a good reason why Bar Keepers Friend should not be used to clean a circular blade?

If not I plan to repackage the stuff as a fancy blade cleaner beginning Monday.

I use Lestoil. It works great just soak the blade for about 5 minutes and then scrub with a brass bristle brush and it is spotless. Lestoil can be found at Ace Hardware

Barkeeper’s friend is a true friend. It’s abrasive enough that it’ll dull your blade, but I can’t imagine you’re really scrubbing a sharp carbide knife tip;) I use oven cleaner as well. Simple Green is a pretty good cleaner, as is greased lightining. Some of the citrus-based cleaners are pretty good, too. For stubborn labels, it’s TSP and GooGone for me.

I’ve used oven cleaner in a pinch, but you can do regular maintenance cleaning
by just soaking the blade in soapy water for awhile and scrubbing it with
a non-metalic brush. Carbide is very hard so a wire brush might be okay too,
but I’d rather not risk scraping away the brazing metal.

If the blade is really encrusted with old gunk, I just shoot it with oven

409 works for me.
Don’t know why Bar Keepers Friend wouldn’t work just as well.

Good ol’ oven cleaner you can get at the super market cheap. Spray it on, let it sit for a few seconds, scrub with a nylon or brass brush, rinse with water, dry, spray on some bit & blade lub to seal it against rust. Been working for me for over 15 years now.

I use the purple cleaner found in the automotive section at Walmart. I just put the blade in the laundry tub spray some of the purple stuff on and the crud just come right off with a little brushing. Rinse off and dry and the blade is like new. This stuff is sold under a lot of different brand names at automove stores, but for some reason is always purple in color.

I used to use Bar Keepers Friend on my bathroom tubs, but the areas would start to scum up pretty fast a few days later. Also used it on the inside of the toilet, and after a few days that damned black “stuff: would start to show up at the water line. So, I switched to Comet Cleanser, and, well, the tub and toilet stay grime and “stuff” free longer, no doubt because of the bleach concentration in the Comet. One thing I do with the tub is scrub it with the Comet and then not rinse it at all. Just let it sit for a day (until the next shower happens) and then rinse it. Wow, does that thing shine!

On the other hand, I once dropped a bath towel in the tub while the Comet was still in there (it was dry, but the green towel still got invisible residue on it), and after I dried off, I put on my fresh, clean around-the house clothes, and then later on went to bed in my undies. I did the towel, clothes, and “go to bed” thing several days in a row afterwards, and then, still a few days later I broke out in a rash. Seems the Comet was now embedded in the sheets after transferrng to them from me after using the towel, and so I was sleeping in a small film of Comet.

Moral to the story, keep the stuff off of the towels. I would hazard a guess that Comet would clean tools, too, and that afterwards no mildew would dare form on them. It might remove some of the red from various Freud circular-saw blades, however. Not sure about that.

The previous story is true, but you can also take it as a joke. I do.

PS: the rash went away after about a week.

Bar Keepers Friend is my Metal cleaner of choice for many tasks. I never thought to use for blades though. I can’t think of any reason to NOT use it on blades, but I typically use a less-toxic degreaser like simple green. Alcohol works ok too.

I read an article on blade cleaners. Regular Simple Green and oven cleaner should not be used they can weaken the braze joint on the blade. You can use aircraft grade Simple Green. Lestoil is cheap and works great. You can also use two cups of water with two tablespoons of baking soda and let the blade soak about two hours and it will pretty much just wipe clean. After i clean my blades I rinse with warm soapy water and then blow dry with the compresor and finally spray with WD-40 to prevent rust. When I install the blade in the saw give a quick wipe with alcohol or mineral spirits.
