Whether windshield wipers need replacement can be determined by observing several aspects. If the rubber blades are worn, causing fine streaks, hazy residues or a water film on the glass after wiping, or if there is a clicking noise during operation, they should be replaced immediately. During routine inspections, you can touch the rubber blades with your fingers; if they are hardened, cracked or have lost elasticity, it indicates deterioration. Additionally, if small water beads remain on the windshield after wiping (known as water beading), you should first eliminate oil film interference before confirming blade deterioration. If there are streaking marks or uneven wiping, it may be caused by deformed rubber blades or improper wiper arm tension. Regular cleaning of both glass and rubber blades is recommended, along with pre-rainy season inspections. Typically, rubber blades last 6-12 months depending on usage frequency and parking conditions. The cost for replacing standard wiper blades ranges approximately from 30 to 150 ringgit.
