Spring cleaning season has arrived, and if you’re the kind of person who spends weekends in the garage with a table saw or router, your tools deserve some attention too. Dirty saw blades and router bits don’t just look neglected. They work harder, run hotter, and leave burn marks on your projects. A good cleaning session can bring them back to life and save you from replacing expensive carbide-tipped equipment before its time.

Here’s how to do it right, without wrecking your blades or bits in the process.

Start by Taking Router Bits Apart

Before any cleaning begins, disassemble your router bits. Bits with bearings require you to unscrew and remove the bearings, screws, and collars. Set those small pieces somewhere safe, like a muffin tin or a magnetic parts tray, because they are easy to lose. Buildup loves to hide around bearings and screw threads, so separating everything first means you actually clean the whole bit, not just the outside. If you have solid carbide bits without removable parts, you can clean those in one piece.

Mix Up a Simple Cleaning Solution

Grab a shallow plastic container big enough to lay your saw blades flat. You have two easy options for a cleaning solution. The first is one part Simple Green mixed with three parts water. Do not use Simple Green at full strength. It can be too harsh on certain blade coatings. The second option is even simpler: one teaspoon of dish soap stirred into one quart of water. Either solution works well for cutting through the pitch, sap, sawdust, and general grime that builds up over time.

Soak, Scrub, and Rinse

Submerge your blades and bits completely and let them soak for about 15 minutes. That soak time does a lot of the heavy lifting, loosening up the sticky residue so it comes off more easily. Then, while everything is still in the solution, scrub with a nylon or brass bristle brush. If that doesn’t get the stubborn spots, move up to a Scotch-Brite pad or a steel scouring pad. For truly tough pitch that won’t budge, a small putty knife can carefully scrape it away. Just work slowly and keep the sharp edge of the blade in mind.

One thing to avoid: steel brushes and harsh abrasives. They can damage the cutting edges and shorten the life of the blade.

If the buildup is especially bad, a few sprays of full-strength Simple Green directly on the problem area, followed by a brass bristle brush, usually handles it.

Dry Everything Completely

This step matters more than people realize. Rinse the blades and bits thoroughly with clean water, then pat them dry with a paper towel or shop rag. After that, use a hair dryer to make sure every surface is fully dry. Pay close attention to bearing holes and threaded areas on router bits, because moisture hides in those spots and rust follows quickly. Nothing shortens the life of a good bit faster than reassembling it while it’s still damp.

Lubricate Before You Reassemble

Once everything is dry, apply a drop of lubricating oil to the bearing hole before reinserting the bearing, and a small amount to the screw threads before putting the bit back together. Wipe off any excess with a clean cloth. Extra oil on the surface attracts sawdust during storage and creates the very buildup you just cleaned off.

Know When to Clean

How often your blades and bits need cleaning depends on how much you use them. The tools will tell you when they’re ready. Dark burn marks on the teeth or along the blade plate are the clearest sign. If your cuts are looking scorched or the tool seems to be working harder than it should, it’s time to pull things apart and give them a good soak.

These are the people, and the tools, that make our workshops run. A little maintenance goes a long way toward keeping the projects coming and the sawdust flying in the right direction.
