DIY House Wash Safety

Always wear the proper PPE! Pressure washing and soft washing can be very dangerous. Be aware of your surroundings. Make sure that your ladders and other equipment is in proper working condition before you get started. Soft house wash chemicals can be irritating to the eyes, skin and respiratory system if not handled properly. If you are not comfortable on a ladder or working with bleach, please call a professional.

Safety Glasses
Safety glasses or goggles should be shatter resistant. Protecting your eyes is imperative.
Always wear chemical resistant gloves that are Sodium Hypochlorite proof. Preferably gloves that cover the forearm.
A polyester hat is bleach proof and will protect your face from overspray.
Bleach will discolor cotton clothes. Wear old clothing or polyester. Long sleeve shirts and pants help protect the skin from any chemicals.

House Wash Equipment

The main things that is needed to soft wash a vinyl house is a ladder, bleach pump up sprayer, a pressure washer, outdoors bleach or liquid pool shock, and detergent. The detergent must be bleach stable. Do Not use liquid dish soap. All hardware stores have house wash soaps or a laundry detergent can be used. A water hose with a high range nozzle can be used in place of a pressure washer.

Soft House Wash Directions

Cover all fragile plants with plastic. Bushes and other shrubs should be thoroughly rinsed before, during and after treatment. Mix the beach and water to dilute the bleach to 1%. The percentage of the bleach should be on the bottle. For instance 2 gallons = 7.57 liters. So for a 2 gallon sprayer and 12% bleach the equation would be: (.12x_ ) / 7.57= .01. This would be .63 liters of 12% bleach in a 2 gallon sprayer. Sorry for the math quiz. Now mix in approximately 1 ounce of soap and shake it all up. Start spraying in 10 foot sections from the bottom up as high as the sprayer will reach from the ground. Once the algae has disappeared, it is ready to rinse. Use the black 65 degree nozzle on the pressure washer or a garden hose to rinse the section. Repeat this process over the entire surface of the exterior wall. Make sure to coat spider webs and other debri with the house wash mix solution. The detergents will make them easy to rinse. It is very dangerous to spray while on a ladder. Be sure that you have a spotter on the ground and take your time. Never mix the bleach in the pressure washer soap reservoir. It will cause damage.
