i seem to go through wipers like crazy, seriously they seem to last me 2 months before they just smeer, am i buying the wrong ones, iv tried bosch, halfords own, tesco's own, even 2 different sets off ebay, i wax my window every time i wash it but this only helps a little, i even tried washing the wipers with no luck, is there some special brand that manufacturers use as thers always last years!

i think you've gotgrease in your washer bottle.sometimes happens after using additives.feel your washer water.does it feel-slimey?

You need to flush the washer bottle out - hot (like boiled kettle) water and white vinigar always works for me, go for a litre of each. Whack it in there and empty it onto the windscreen using the washers. Change the wiper blades, again and use some ready diluted screenwash - Halfords premium is pretty good, IMHO.

Also well worth a punt is a full-on RainX treatment. Give the glass a bloody good clean and then apply the RainX as prescribed on the bottle. Ruddy marvelous stuff, anything over 40 and the rain eff's right off the glass with no wipers required. When you do use them they whip over the glass and it seems to stop the grot from sticking quite so bad. Well worth 6 quid, dont bother withthe antimist or glass cleaner though. Antimist is crap and glass cleaner no better than Mr Muscle, their screenwash is crap too
