can anyone please tell me how to get a smear free inside windscreen,i made stupid mistake of buying a windscreen demister cloth,and its made a real mess of it,streaks all over it,and no matter what I've tried,it's still the same...thanx in advance.
I use vinegar (applied with lots of kitchen towel). It makes your car smell like a chippy for a short while afterwards but it's guaranteed to produce a really clean, streak-free finish. (If your windscreen is totally clean it's impossible for it to mist up. Water droplets can't adhere to glass; they can only adhere to the dirt on the surface of the glass).
a company called bonnymans do crystal clear .its is the best i have found . or auto smart do it they also do somthing called glass glo it is a cream but it is great .just put it on like windowlene and wipe it off with a dry cloth ....say good bye to smears for ever.
Best glass cleaner available for my money is simple methylated spirit. Find in B&Q etc. Cheap and effective inside and out. I also put 50/50 in my washer bottle during the frosty times and then my bottle does not freeze up. Simples.
