Saw blades that are used a lot are covered with dirt after a while. In this article, you will find out in detail how to get rid of dirt quickly and why regular cleaning is so important.
Soiling on saw blades
The biggest source of contamination on a saw blade is tree sap. Softwood in particular has a very strong tendency to resinify - this also applies to many pieces of pine and spruce.

When sawing, large amounts of tree sap can escape within a very short time. The resin is sticky and sticks to the saw blade. Over time, this sticky mass also attracts more dirt and, above all, wood dust.
Sawing with dirty leaves
The sticky mixture of resin, wood dust and dirt creates a surface on the side of the teeth that has high frictional resistance. As a result, the wood is partially burned during sawing (especially with circular saw blades) and gets unsightly black spots on the saw edge.
In addition, saw blades that are not cared for are broken much faster than cleanly cared for. A saw blade that has been cleaned more often lasts much longer - and is also easier to sharpen.
In the case of dirty saw blades, individual teeth must first be filed through a massive, already caked layer of dirt - with the result that teeth become unevenly sharp (the encrusted teeth are hardly sharpened, others even more).
Remove resin dirt
Special resin removers, such as those used for cleaning chainsaws, are certainly a good option for all saw blades.
Manufacturers such as Ballistol also have resin cleaners in their range, and there are also some universal products that can also dissolve the sticky resin well.
The insider tip of the woodworkers is conventional oven spray - after the shortest possible exposure time (10 minutes is usually sufficient, the cleaner should not act longer) you can simply rinse the saw blade with water. Much of the resin will have already been removed.
After rinsing with water, the saw blades should be treated with oil - one option is camellia oil, for example, to prevent rusting.Tips & Tricks Thinner is also good dissolving resin, besides some other agents are also rumored again and again - such as brake cleaner. Ordinary oven spray, however, works surprisingly well - and usually better than any other insider tip.
