blades have a finite service life, as they perform a hazardous duty in harsh
conditions. Dirt, debris, and road grime abrade wipers, and sunlight breaks
down their rubber edges. Beyond visibility, be a wholesale wiper blade advice you that it is important not to wait too
long to replace a blade, as a torn wiper blade can allow the wiper arm to rub
against the glass, possibly scratching and ruining the windshield.
blades come in many sizes, even on the same car. Look in your car's owner's
manual, measure the blade, or ask at an auto-parts store for the proper fit.
Major brands that you are likely to see include Anco, ACDelco, Bosch, Goodyear,
Michelin, PIAA, Rain-X, and Trico. Prices vary greatly depending on the brand,
type, and size. For a smaller wiper blade, you can pay as little as under $10
and for a large blade of 24 or 26 inches, you can pay $25 or more.It's becoming harder to find replacement inserts where only the
rubber is replaced into the existing frame and while inserts can save money,
installing them requires deft use of needle-nose pliers. Experience shows that
replacing an insert can be a frustrating task whose grief simply isn't worth
the money savings. It's often more convenient to replace the whole blade
assembly—just pull the old wiper off the metal arm and push the new one on
until it's tight. (You might need a small screwdriver or hammer to tap the old
blade off.) Our research shows that most car owners replace the assembly,
rather than just the blade.
All wiper blades are marketed with great promise, and it can be
difficult to sort through the claims and hyperbole. In our testing, we have found
that some of the best blades are among the least expensive. Lesson here: Don't
equate a high price with high quality.
When new, we saw that all of the tested windshield wipers blade provided
very good or excellent performance initially, but most quickly degraded after a
few months of regular use. Depending on the model, deterioration showed up on
the windshield as streaking (leaving lines of water behind), smearing of the
water (instead of clearing it), or missed areas of wiping. Because we found
that a wiper blades will typically provide very good or better performance when
new, with performance dropping off quickly, most blades should provide adequate
performance after about six months when they should be replaced. Consequently,
we no longer test them.
When we last tested wipers, we conducted an exhaustive assessment
of more than a dozen windshield wiper blade models on 185 staff members' cars. When
the project started, about half those cars had wipers that needed replacing,
showing that drivers often don't notice the slow degradation and leave wipers
on longer than they should. Therefore, as a wholesale wiper blade, our experience suggests that beyond a
quick monthly inspection, it would be wise to plan for wiper replacement twice
a year. Consider going with the change of seasons, replacing the blades with at
the beginning of winter and again for summer—two seasons that prove
particularly challenging for wipers blade.
