You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.

There are a few qualifying questions you can ask a professional window cleaner to help you decide if it’s the right company for you:

• Does your price include the inside and outside of the windows?

• Will you clean the tracks, rails, and other internal components?

• Are you fully insured?

• How many years of experience do you have?

• What kind of cleaning products do you use?

• Do you have any customer references?

• Do you provide any other services, like exterior power washing?

Because the built-in blinds are encased in glass, they should not get dusty. You might, however, find that your door’s window panes get dirty. If that is the case and you wish to clean your patio door’s glass, first remove any loose debris with a small vacuum or brush. Next, fill a bucket with warm water and some mild dish soap. Dip a clean rag into the bucket and wet the glass on your patio door. Dry the glass with a clean microfiber cloth.

Cleaning your windows not only improves your home’s curb appeal—and, therefore, property value—but it also prolongs the life of your windows. Clean windows make a big difference from the outside, so if you’re selling your home or plan on selling, window washing is an affordable way to make your home stand out. Additionally, cleaning the tracks and moving components in your window can help them last longer, potentially saving you money over time on window replacement costs and repair.
