How to Clean Pet Clipper Blades? | The Right Way, Step by Step

For the full breakdown, see our best Clippers for Dogs with Curly Hair guide.

Nobody wants to stop mid-groom because the blades are pulling instead of cutting. The fix for that drag is a short cleaning routine. Keeping the blade free of hair, sanitized, and properly oiled also stops rust and keeps the motor running smoothly. It takes about five minutes, and your dog stays calmer when the clipper sounds and feels right.

What You Need Before You Start

Gather everything first so the job goes fast. You’ll want a cleaning brush, a Wahl-approved blade cleaner or disinfectant spray, and blade oil. A can of compressed air helps, plus a soft cloth for drying.

Some blades rinse off, but most don’t. Wahl says its rinse-and-clean guidance applies only to rinseable snap-on/off blades or waterproof trimmers, so check your manual first. Submerging a blade that isn’t rated for it can force water into the motor and ruin the tool.

The Basic Cleaning Routine

Step 1: Remove loose hair. Brush the blade while it’s still attached to the clipper to pull out trapped fur. Wahl suggests removing packed hair by hand or with the supplied cleaning brush. Compressed air helps blow stubborn hair out of tight spaces.

Step 2: Disinfect the blade. Spray an approved disinfectant like Wahl Hygienic Clipper Spray across the cutting surfaces. Don’t soak it, and don’t let the spray sit longer than two minutes, because Wahl warns that extended contact can damage the blade.

Step 3: Dry the blade completely. Wipe it with a clean cloth and let it air-dry. Never store a wet blade; Wahl says leaving blades wet can cause rusting.

Step 4: Apply blade oil. Put a few drops on the cutting edges using the manufacturer’s method, then run the clipper for a few seconds to work it in. Wipe away any excess oil so it doesn’t attract more hair. Only use oil your clipper’s brand approves. Wahl warns that other brands’ oil may damage the clipper or blades for its 5-in-1 blade.

Deep Cleaning a Wahl 5-in-1 Blade

When hair has built up inside the blade, a surface clean isn’t enough. Wahl’s help guide for its 5-in-1 blade walks through a deeper process that opens the blade up.

• Set the blade to the #40 setting before removal.
• Remove packed hair by hand or with a cleaning brush, plus canned air if needed.
• Open the top section of the blade to clear buildup inside, then reattach it.
• Disinfect with Clini-Clip for two minutes maximum.
• Oil using Wahl’s three-point method, then wipe off the excess.

This deeper clean applies specifically to Wahl 5-in-1 blades at the #40 setting. Other blades may not open the same way, so follow the instructions for your exact model before taking anything apart.

For dogs with curly coats, blade maintenance matters even more because dense hair clogs faster and puts extra strain on the motor. If you’re still using a clipper that struggles with thick fur, see our roundup of the best clippers for dogs with curly hair for models built to handle the workload.

Common Mistakes That Ruin Blades

Most blade failures trace back to the same handful of errors. Skipping the initial hair removal step means the spray and oil can’t reach the metal surfaces where they matter. Leaving cleaning spray on the blade too long causes damage rather than preventing it. Storing or reattaching a wet blade is an open invitation to rust. And using non-approved oil where the manufacturer warns against it can degrade the blade’s performance or damage the clipper itself.

If your blade is pulling, nicking, or overheating, check whether you’ve been consistent with this routine. A sharp blade that’s properly oiled and clean should glide through the coat without tugging. When it still won’t cut after a full clean, the blade may need professional sharpening or replacement.

FAQs

Can I use rubbing alcohol to clean clipper blades?

Rubbing alcohol can strip the blade’s lubrication and may not fully disinfect. Manufacturer-approved sprays like Wahl Hygienic Clipper Spray clean and sanitize without leaving the metal dry. If you use alcohol, follow it immediately with blade oil.

How often should I clean pet clipper blades?

Oil the blades before every grooming session, and clean off hair buildup mid-session if the blade starts to drag. A full deep clean works well about once a month for regular home grooming, or whenever you notice the blade pulling.

What do I do if my blade starts rusting?

Light surface rust can sometimes be polished off with a fine abrasive and then oiled heavily. Deep rust pitting usually means blade replacement, since the damaged edge will keep snagging the coat.
