When the Sun is low my Windscreen seems to sparkle. A quick Google and seems I am not alone. Has anyone found a glass cleaning product that works. Claybar seems to be one method, just wondered if any more modern product that works.
Bought it last August and used it straight away. Just now starting to wear off after nearly 12000 miles. Very happy with it, it's a faff to apply correctly but really does work and work well. I'll be reapplying soon.
