Ways to avoid streaks
Use good window cleaner
You need to use a good window cleaner in order to avoid streaks. This is because few cleaners require the proper amount of dilution or they will cause more streaking. Remember that a concentrated cleaner leads to formation of streaks. It is recommended to buy a cleaner which is specially built for removing grime on windows.
Use a clean absorbent towel
You should get an absorbent towel for cleaning purposes. Remember to clean the surface thoroughly to prevent dirt from spreading which can eventually cause nasty streaks.
Use enough cleaner
You are required to use enough cleaner in order to prevent the window from drying up quickly. If this happens, you will only be spreading the dirt and grime around and not really be cleaning anything properly.
Spray cleaner on the window
You need to spray the cleaner directly on the window. Avoid spraying it on the upholstery or plastic surfaces of the car.
Cleaning of the interior car windows
Cleaning door windows
For cleaning door windows, you need to slightly roll them down about an inch before cleaning. Doing this will help you clean the top part of the windows.
Use a rag or old newspaper
You should use a rag or old newspaper in order to protect the surface below the windows. Simply place them underneath the glass to prevent any cleaner spilling.
You need to spray the cleaner on the glass and use enough to cover the entire area. In case you have tinted windows, it is recommended not to use a cleaner with ammonia as this can cause damage.
Use microfibre cloth
You need to wipe the window with a microfibre cloth. Later you need to get another microfibre cloth in order to dry and buff the window.
