Hi all...i have just replaced some cheapo Flat Blade wipers....Vistapro....with some Bosch Superplus conventional ones. However,the bloody annoying squeak as the blade clears the windscreen on the drivers side is still there. Ive even gone as far as soaking a rag in vinegar and giving the screen a good scrub for 10 minutes but it made no difference. Sometimes the noise is on the upstroke,sometimes on the downstroke and sometimes on both strokes...any ideas what to try next greatly appreciated.
