Car glass cleaner to help get your windows looking smear free and sparkling. Keep your windscreen clear with our glass polish or glass cleaner in either a trigger or aerosol can. These products can also be used around the home for those tough-to-keep-clean glass showers or just your windows. For example, Autoglym Car Glass Polish contains specialist cleaning and polishing elements which quickly and easily remove all common contaminants, leaving a crystal clear, smear free finish. Often people are tempted to use household cleaners on their car, but be aware that many domestic glass cleaners contain wax and silicone for cosmetic effect. This is fine in the house, but may cause dangerous smearing in wet weather if used on your windscreen. Stick with car glass cleaner to be on the safe side.
