Vaporises away with no streaking or smearing, for perfectly clean windscreens. No aggressive solvents, ammonia or salt, safe for all paint, rubbers, chrome and plastic trims. Won't remove or affect quality waxes, sealants or paint protection coatings at the regular daily use ratios. Regular daily use is a 20:1 ratio, so this 1.1 litre concentrate makes up to 23 litres. Cleans off heavier kamikaze bugs and road grime you get on bigger road trip with a 5:1 mix ratio. Does not damage or create stress cracks in polycarbonate headlights. Lubricates wipers so they work better and reduce wiper chatter. Anti-corrosives to stop rust forming on wiper arms and around windscreens. Won't leave water spot / etch marks, especially when used with distilled or filtered rain water. Smells great, so you (or the car behind if you have poorly adjusted wiper jets) can faintly smell it through the car after each use. All Australian developed and made!
