Is it safe to clean saw blades with Black Magic Bleche-wite? The reason I am asking is because I used it on a chain saw blade to get the pit off and it worked really good. Just wondering if it would work as well on saw blades with out doing any harm.

Don’t know but personally I wouldn’t use it for cleaning saw blades or router bits. Fantastic works well and isn’t all that expensive either.

The only thing you would not want to use to clean saw blades is something that might damage the top finish that some blades, or possibly an acid could etch the metal on bare steel. The Black Magic stuff should work fine.

I use a Beoshield blade cleaner I get at Woodcraft. Not cheap but a little goes a long way. Then I spray on a silicone protective coating that I use on my table saw top to prevent rust and further build up.

For 50 years I have been cleaning my table saw blades with spray can oven cleaner. Works great and quick. Smells terrible and you should probably use rubber gloves, but often I don’t. There has been concerns that it affects the carbide inserts, but I have never seen any problem over the years and put this down to rumors. When finished, wash it off with water. I use a hose outside.

According to the Safety Data Sheet, Black Magic Bleche-wite does not contain any chlorine bleach. It is a mixture of water, 2-butoxyethanol (an organic solvent), sodium alkyl benzene sulfonic acid (a detergent) and sodium metasilicate. The latter is a very alkaline substance used in numerous cleaners such as “green” non-phosphate TSP replacements. It can bind to metals helping soften water and coagulates with metal ions and other gunk to precipitate them. So basically it is like dozens of other cleaning products in the marketplace. My only concern would be that the metasilicate may leave the metal surface prone to corrosion. I would rinse the blade very well and perhaps apply a coat of paste wax or similar protectant.

I used to use oven cleaner but switched to simple green when I found a jug in our pantry. Much more pleasant to work with versus the oven cleaner. I have also used ammonia with great success (I use it to clean my drum sander strips)

Saw blades are tough to damage with most cleaners, but some will remove paint, lettering, and coatings. What’s best to use is subjective to some degree. So many things work well on blades and bits…the important thing is to clean them. I have used some task specific cleaners that cost quite a bit more than household cleaners, but it’s hard to recommend them over common cleaners like 409, LA’s Totally Awesome, Fantastic, Greased Lightning, Goo Gone, Simple Green and others. My advice is to use what you’ve got, and use it often!

Hot water and a cup of simple Green!
I use a oil change pad from the dollar store and just let the blade sit it the solution for a few min then use a old tooth brush to clean the teeth. Rinse it off and just put a lite cote of oil on it if your not going to put it back in the saw and start using it.
Depending on what I cut, I do clean the blade quite often.

What knotscott said. For me that usually means simple green or 409 but most any household cleaner like that works.
