Q. What can I do to stop the rubber of my wipers screeching over the windscreen? A friend suggested using vinegar.

A. Dragging blades are usually caused by dirt on the wipers or screen. To prevent a build-up of grime, always use a good screen washer additive (such as Angelwax Clarity, £7.95, plus £3.50 postage, at angelwax.co.uk).
Then, every other time you wash your car, use a quality screen cleaner, such as Dodo Juice Clearly Menthol (£11.91 at amazon.co.uk — see our review here). You could try vinegar but don’t splash it on paintwork.
If you’ve had the wipers for more than two years it’s time to replace them (the assembly, not just the blades — see the selection at Halfords.com) and ask your garage to check they have the correct tension.
