No problems with my RHD here in Australia. My approach is to clean the windscreen regularly (at least every fortnight, more frequently if traveling on damp, dirty roads) and also change wiper blades every year. My experience has been that contaminants on the screen are usually the problem, which results in erratic wiper performance and wear on the rubbers. I also use BMW washer cleaner additive -- I probably should use something generic and cheaper, but it's a concentrate....
