What Chemicals Will I Need?
You’ve got some choices when it comes to cleaning solutions. First, let us tell you a bit about using bleach on vinyl siding.
Bleach is used to kill mold spores. If you just use soap and water, you would need to clean your vinyl siding twice a year. It is recommended that you use one quart of bleach to every 5 gallons of cleaning solution. If you use bleach, you’ll go from cleaning your home every 6 months to cleaning every 9-12 months!
There are various solutions you can use to clean your vinyl siding. Here are some other recipes you can try.
Remember! The most effective bleach to cleaner ratio is
1 quart bleach : 5 gallons cleaner
Diy Power Washing Solutions
***Remember! These solutions are best effective when scrubbing the siding by hand. If using a pressure washer, verify on the user manual of your machine that you can use a DIY vinyl siding cleaning solution.

What If My House Is Really Moldy?
So you’ve been putting it off for a while, right? If your vinyl siding has had mold and algae on it for 3-6 years or beyond with no attention, you might need to adjust your cleaning strategy. And no, that doesn’t mean just start pouring straight bleach on your wall.
A 1 time bleach job before you clean will do the trick and kill the mold spores, but make sure you dilute the bleach solution.
A small concentration is required to kill the mold spore, such as 1-2 cups in a 5 gallon bucket of water. That will still give you the killing power but it will be diluted enough so it doesn’t hurt the parts on the pressure washer, the siding, or the plants.
You’ll need a dilution rate that will do the job that it’s designed to do, and not kill anything else. Also, if you’ve neglected the exterior of your home, you may need this how to guide for cleaning gutters! Education is key in anything, and knowing what you’re doing will help in the long run when it comes to cleaning your home!
Best Way to Clean Vinyl Siding
There is a big dispute about this topic in the industry. No doubt, common notion says that hand washing is easier on the siding, but is that really true? We’ll explain preparation and execution of both ways just to help you make the decision.
Hand Washing or Power Cleaning. Which Is Better?
In order to hand wash, you’ll need to purchase the correct brush. You’ll need to get a brush with tougher bristles so they can get every part of the siding clean. You’ll need to wet the wall, then scrub it with some elbow grease to get the stains out, let the solution sit, then rinse it off.
In order to power clean, you’ll need the proper equipment, including the proper knowledge of how much pressure to use on the type of siding you have on your home.
