wiper noise

[ksm1213]

My wipers give a lot of noise while moving.
i put new ones on but still same noise.
someone said maybe the wax in car wash soap stays on glass to make such noise.
But anyone know how to dissolve wax ?

many thanks

wash window with alcohol should stop the noise. I had the same problem with my car but it was tree sap that was causing the noise.came off with alcohol. Try it.
