How often should I replace wiper blades?

About once a year, or as soon as they streak, chatter, or leave uncleared bands across the glass. Sun kills the rubber faster than use does — a car parked outside in a hot climate may need blades every six months, while a garaged car in a mild one can stretch past a year.

Why do my brand-new blades still streak?

Usually the glass, not the blades. Road film, wax residue, and tree sap cause most "bad blade" complaints — clean the windshield thoroughly and wipe the rubber edge with a damp paper towel or rubbing alcohol. If they still streak on clean glass, check that you bought the right lengths.

Are expensive beam blades worth it?

Beam-style blades press against the glass more evenly, so they handle snow, ice, and high-speed wind lift better than conventional framed blades. In a mild climate a standard frame blade works fine. Fit matters more than price — the correct length clicked solidly onto the hook beats a premium blade that does not match.

What about the rear wiper?

Same job, usually a smaller blade — and it is the one everyone forgets exists. Rear blades on hatchbacks and SUVs often use a different connector than the fronts, so look it up in the fitment book separately rather than assuming.

How to Replace Wiper Blades

About 10 minutesEasy6 steps

Wipers streak, chatter, or smear for one reason: the rubber edge is worn, and no amount of washer fluid fixes it. New blades take about ten minutes to fit, need no tools, and cost $10–25 each. The only detail that varies is the release mechanism where the blade meets the arm — once you find the tab, the swap works the same on almost every car.

The one real risk is the sprung wiper arm snapping back onto bare glass — keep the towel under it the whole time the blade is off. Work with the ignition off and the wipers in the parked position. If the arm or the J-hook itself is bent or corroded, stop there: a new blade will not fix a damaged arm.

What you'll need

New wiper blades matched to the car (size is in the manual or the parts-store lookup — driver and passenger sides are often different lengths)
Towel (laid on the glass where the arm could snap back)
Rubbing alcohol or glass cleaner (for the streak test at the end)
