If your saw blades aren't cutting properly, it may not be because the blade is dull. It may just need to be cleaned.
Softwoods are the materials most likely to clog up a blade. This will leave a residue of tar and gum on your blades that will slow down the cutting rate or leave discoloration on your wood. They will also speed up the dulling process of the blade. Woodcraft Resin Remover removes encrusted sawdust and pitch from saw blades, router bits, planer blades and other cutting tools.
Check your circular saw blades often, and keep them clean. The same rule applies to your other blades and bits. Use the same cleaning methods.
After the blades are clean, give them a coat of silicone spray. This will help slow down the buildup of tars, resins, and rust.
