Avoid using window cleaner on old window tint as this may result in the tint coming off.
The glass can be one the the hardest and most awkward areas of a car to clean. It’s very easy and common for people to attempt to clean their cars glass, only to end up creating more unsightly marks and smears. It’s important not only to regularly clean your glass, but to also polish it. This helps to keep it looking cleaner for longer by repelling water and dirt and it also helps to prevent it from misting up during cold, damp periods. The more often you clean and polish your glass the easier it becomes to achieve great results with less effort and time.
The first stage of cleaning your cars glass is during the wash process. This will remove the main exterior contaminants & dirt. Stubborn bug splats can be removed with a designated bug remover product or by claying the glass as you would the paintwork. Glass can also be clayed in order to remove any bonded on contaminants like tar and tree sap. The area should then be rewashed, rinsed and dried.
After washing and removing any bug splats or bonded contaminants you can begin to clean the glass with a designated glass cleaning product. It is very important to use the right type of cleaning towel/cloth to prevent you from creating smears and leaving annoying particles behind. You should use a clean thin lint free cloth/towel, ideally one made specifically for cleaning glass. It’s also important to clean the glass in the shade instead of direct sunlight as this too will help reduce the chance of creating smears.
Apply the cleaning product sparingly directly onto the glass, do not over apply the product as this will lead to smears. Work the product in using linear up & down and side to side motions ensuring all areas are covered paying particular attention to corners and edges. The key to preventing smears it to frequently turn and fold your cloth or towel to reveal a fresh, dry clean surface.
Once the exterior is completed you should move on to cleaning the inside of the glass using the same technique. The inside of the glass can be more awkward to clean due to the angles of it so spend a little time ensuring all areas are covered and again frequently turn and fold the cloth.
Once sufficiently cleaned, you should polish your glass with a designated glass polish product. This should be applied with a micro fibre applicator pad then worked in with both linear and circular motions. Once the polish has dried/cured it should be buffed off with a clean, high quality micro fibre towel.
The polishing stage will help to lift off any small smears that may have been left behind during the cleaning stage but ensure you thoroughly buff off all areas otherwise you will just replace the smears with polish residue. Both the exterior and interior of the glass can be polished but depending on the product being used some dust may be created during the buffing process so consider this factor if you are also cleaning the rest of you cars interior.
