We Make Wiper Blades. Here's Why You Don't Need to Buy New Ones.

A wiper blade refill is just the rubber strip that actually touches your windshield, without the metal or plastic frame. It’s the part that wears out, not the whole blade. Most wiper frames are built to last years, but the rubber insert only lasts a few months. Instead of tossing the entire setup, you can swap out just the rubber for a fraction of the cost.

Here is how to do it like a factory technician.

Step 1: Protect Your Windshield (Do Not Skip)

Before you even touch the wiper arm, grab a thick towel or rag and fold it over the glass right under the arm. The spring inside that wiper arm is surprisingly aggressive. If your hand slips while you’re pulling the blade off, that bare metal hook will snap back and crack your windshield in a millisecond. Pad the glass first. Always.

Step 2: Pull the Assembly

Lift the wiper arm until it stands up. Find the release tab where the blade hooks onto the arm, press it down, and slide the whole assembly off. Set it on your towel.

Step 3: Gut the Old Rubber (Save the Splines!)

Look at the ends of the metal frame. You’ll see little plastic tabs locking the rubber in place. Bend the frame slightly to release the tension and slide the old, crusty rubber out.

Here is where most DIYers mess up: Do not throw away the metal splines. Inside that old rubber are two thin, flexible steel strips. They are the spine of the wiper. They give it the exact curve it needs to hug your windshield. Slide them out of the old rubber and keep them safe. If you toss them, your new refill will just flop around and be completely useless.

Step 4: Prep the New Rubber

Take your new wiper blade rubber replacement. If it’s longer than your old one, measure it and trim it with a utility knife. Now, take those two steel splines you saved and slide them into the channels of the new rubber. Push them all the way through so they sit flush. (Note: If you bought our premium refills, the splines are already pressed in, so you can skip this step. But for standard universal refills, this is mandatory.)

Step 5: Lock It In

Slide the new rubber-and-spline assembly back into the metal frame. Push it through until you feel the end tabs snap into their locking notches. Give it a firm tug. If it slides, it’s not locked, and it will fly off the second you hit the highway. Make sure it’s seated tight.

Step 6: Reattach and Test

Hook the assembly back onto the wiper arm until you hear that solid click. Lower it gently onto the towel, remove the pad, and fire up the wipers with some washer fluid.

A Quick Note from the Factory Floor

If you refill wiper blades and they’re still streaking, don't blame the rubber. 99% of the time, your windshield has a layer of road film or tree sap. Grab some glass cleaner and scrub it. If they’re still chattering, your wiper arm might be slightly twisted from ice or abuse, and you might need to gently bend it back into alignment.

We build these frames to last, and the rubber to wear out. Windshield wiper refills are the smartest way to maintain your car. Do it right, and you’ll never need to buy a full assembly again.
