Even a clean and polished vehicle does not really sparkle until you clean the windows. Traditionally one of the least favoured valeting tasks, windscreens and windows are easy to clean with Autoglym Car Glass Polish. It contains specialist cleaning and polishing elements which quickly and easily remove all common contaminants, leaving a crystal clear, smear free finish. Use inside and out. 
Many domestic glass cleaners contain wax and silicone for cosmetic effect but may cause dangerous smearing in wet weather if used on your windscreen. If you have acrylic or plastic windows use Autoglym Fast Glass which is formulated for use on these surfaces.
