Test triumph for SONAX XTREME Windscreen wash
The German technical monitoring body, GTÜ in cooperation with the Auto Bild magazine has tested nine current summer windscreen cleaners. The clear test winner, with the rating „highly recommended“, was the SONAX XTREME Windscreen wash, in a practical three litre container, which proved to be by far the best cleaning performance in the test field.
One other product also received the rating „highly recommended“, despite losing marks in the cleaning of typical summer dirt such as insects, six other windscreen cleaners, with significantly lower overall scores, still managed a „recommended“. One other cleaner, which showed obvious weakness in dissolving the typical summer dirt contamination, was rated by Auto Bild and GTÜ as „not recommended“.
