Any cleaner made specifically for blades can be used to remove resin and pitch from the blade.
I totally agree with Shane. I strongly suggest only considering cleaners formulated specifically for removing resin, glue and pitch from blades, bits, cutters and knives used in woodworking.
We must remember that we need not only to keep our blades clean and keen, we also must never transfer any substance to the wood which will interfere with finishing the wood. Back in the 1930s when I was being taught woodworking while I was a child using too much light oil to protect hand saws, chisels and plane irons from rust could cause voids when staining the wood. The nasty thing was you could not see the latent spots before it was too late!
During the first Festool End User Class taught by Steve Bace and Brian Sedgeley in Henderson, Steve mentioned dangers of using silicone lubricants because of the void danger. Later in the Solid Surface Class we came to understand why it is bad policy to mix wood dust with SS fabrication or SS dust with wood before it is finished.
Over the years I have used several special blade cleaners. When I resumed professional cabinet making in 2006 I followed the recommendation of my trusted Festool dealer who also sells CMT products. CMT Orange worked for me. But when I started to recruit my master cabinet makers in 2009 4 of the 6 preferred the Felder cleaner. The seven of us conducted tests while the new shop was being built in early 2010. For us the Felder cleaner has proven to work the best.
I did buy an industrial ultrasonic cleaning machine large enough to handle the 550mm blades of the Felder slider saw, using a round pan and the 24" planer/jointer knives with a different pan.
With respect to the blog, I personally shutter at the concept of using laundry detergent which requires a spray to prevent rust after drying. How could a substance which prevents rust not cause voids in a stain finish?
Everyone else's mileage will vary. Trust me, nobody on my payroll would try cleaning my blades with laundry detergent!
