Yes, you can use it. It's very effective at breaking down grime and buildup. Some people might worry about the solvents harming the rubber, but auto windscreen wipers are a part that wears out over time and should typically be replaced every year. Additionally, it works well as a deicer too.
New wiper blades usually cost $10 to $30 each, while premium options like silicone or beam blades range from $20 to $50. Wholesale prices are often $5 to $15 per blade, depending on order volume. Comparing prices at auto parts stores and online is recommended.
