One of the reasons there are many window cleaning products on the market is because glass gets stained.
Some stains are easy to clean. All you need is a rag and some warm water, and suddenly your window is squeaky clean again.
However, there are times when the stain is more persistent. For these, you need either window cleaning products or the services of professional window cleaners.
Here at Perth Window Cleaning, we are experts in dealing with persistent stains. Here is a look at the common types of stains on glass and windows.
Hard water stains are among the most common. These look like water spots, but with a greyish white coloration.
The stain comes from mineral compounds in the water, which remain after the water has evaporated. Shower doors and windows near sprinklers tend to show these most often.
When glass oxidises, it can also leave stains. Metal screens on windows get these regularly. The sign is a grey haze over the glass panels. These can be avoided using sealants but can be tough to remove once they're already there.
Finally, chemical damage can persist as a problem. Some folks use aggressive chemicals for their window washing, thinking "stronger is better." As window cleaning professionals, we advise against this because it can damage the surface of the glass and leave scratch-like marks.
Whatever the nature of the stain, you can rest assured that our professionals have seen it before. They have the tools and the knowledge to remove these stains without compromising your window.
In a worst-case scenario where the stain is there to stay, they can also recommend alternate courses of action.
