It’s a common fear. As soon as your windows are washed, it will rain. Your windows will be dirty again.

Fear no more. Rain does not dirty your windows. Dirt does. It’s all about the TDS.

What’s TDS?

Water on windowTotal Dissolved Solids. The TDS measures the amount of other materials that are dissolved in water. Minerals, salts, metals, wood dust – anything that is not the hydrogen and oxygen that make up water. All this extra “junk” is what dirties your windows.

How? These solids cause spotting on your glass. Rainwater itself has a very low TDS, usually around 10 parts per million. For comparison, your tap water TDS is usually 140-400 ppm. Tap water will spot windows.

This means rainwater alone will not cause spotting. However, if dirt is already present when it rains, the rain moves the dirt around and focuses it into a spot.

What’s the solution? 

Clean windows. If rain arrives and there’s no dirt on your windows to mix with it, you will have sheeting action rather than spotting. The more frequently you clean the glass, the less the rain will spot. There will be no dirt to mix with the rain and form spots.

Clean windows will actually benefit from the occasional rain. The rainwater will help keep them rinsed clean. If dirt accumulates, this is when the rain will result in dirt spotting.

Stay ahead of the rain.  

Don’t fear the rain. Be prepared for it. Get rid of the dirt. Service by Central Window Cleaning will keep your windows clear and sparkling.

Very happy customer here! They were incredibly responsive after I submitted initial inquiry. Website was great...easy to use for getting an estimated quote. They accommodated our schedule, answered all my questions. The guys doing the work were friendly and professional. They took swift action when a couple of touch-ups were needed. They cleaned the entire exterior of the house...looks brand new. Did all of the windows inside and out, including skylights and high window in cathedral ceiling living room), and one hard to reach ceiling fan. Great job, would definitely use this company again!

I work at Subway in Natrona Heights. Our window cleaner each time is MIKE. He always comes and does a spectacular job on the store windows. He is very professional and easy to deal with. I would recommend MIKE and this service to any business that needs a reliable and quality company to clenched their windows.

Central Window kept us informed of arrival date and time of arrival. They appeared when they said they would. Clayton and Anthony did an amazing job on windows coated with grime inside and out from construction. They worked efficiently. They were considerate of our home. They were pleasant to have around. They were wonderful. The results are wonderful. I highly recommend Clayton and Anthony and Central Window Cleaning.

Our window washer was on time and did a very thorough job. One of our storm windows was broken but the company will have the glass replaced and the storm window returned to us. Overall we were very satisfied with the work done.
