Hey guys, was sifting through a few posts and can't find exactly what I'm looking for....
Think my windscreen got sprayed with diesel or some such greasy sh!t whilst driving the other day. When use the wipers it clears water but sort of 'blooms and beads' and is difficult to see then clears again with wind speed.
Basically bought new wipers but before fitting wondered if there was a decent cleaner/cutter suitable for windscreen, that won't break the bank, don't want to use vinegar

Any relevant suggestions gratefuly received
