Vinyl siding is not high maintenance. You don’t need to clean vinyl siding every month or even once in six months. Properties located in very dusty areas or where the siding gets stained quickly will require a more frequent cleaning schedule. As a rule of thumb, vinyl siding should be pressure washed once a year. If the siding looks visibly clean and doesn’t have any mold or mildew, grime or debris buildup, then you can pressure wash it once every two years.
Vinyl siding in damp areas or under the shade, in moist places or where there are factors contributing to the growth of mold and mildew will require frequent cleaning. In some cases, vinyl siding may have to be washed twice a year. However, not all types of vinyl siding can be safely and effectively cleaned with pressure washing. Some manufacturers clearly recommend alternate methods of cleaning or washing.
Advantages and Disadvantages of Pressure Washing!
Pressure washing is effective, is an easy method and can clean vinyl siding in very little time. The efficiency and relative affordability make pressure washing highly desirable. It is particularly useful to get rid of stains and mold. However, pressure washing also has the risk of damaging the vinyl siding when not done by a professional. Too great a pressure and it may crack the siding. Wrong angles or voluminous supply of water can also damage the structure on which vinyl siding has been installed. You should always hire an expert and not try to pressure wash vinyl siding as a DIY project.
Choose the best method of cleaning/washing!
Pressure washing is not appropriate for certain types of vinyl siding. You may want to talk to your manufacturer before you choose pressure washing. Expert pressure washers know which type of siding would have no risk of damage so you can also act upon such advice. Don’t go against the manufacturer’s recommendations that would void the warranty.
Vinyl siding can be cleaned with soft bristled brushes having long handles or soft cloth if you can reach out to the entire siding. You can use nonabrasive cleaning agents that have been proven to be effective at cleaning but would not damage to vinyl siding. If you are worried about mold and mildew, then you could use household cleaners such as Fantastic or Windex. You can make homemade solutions of seven parts water and three parts vinegar, you can mix 1/3 cup of powdered laundry detergent with 2/3 cup of powdered household cleaner and blend it with one quart of liquid bleach and one gallon of water.
You may want to use pressure washing once a year or once in two years and use other methods for seasonal cleaning.
