Anything that can get dirty can get clean and that goes for your home as well.

This guide is for vinyl and aluminum siding only.Here's what you'll need:Power Washer with chemical injector option/nozzles (Rated for 2-4 GPM)Power washer hose (50 feet or more)Power washer wandBleachBlue Dawn Dish SoapPPE: Gloves and eye protectionOptional: Pump sprayer (For tougher stains)Before you start:You need to first mix your cleaning solution, go with 50% bleach and 50% water in a container or your power washer's chemical tank.

Also add in about 5 ounces of Blue Dawn Dish Soap.

Rinsing of vegetation(before and after) must be done to prevent the plants/flowers/shrubs from being burned by the bleach.

Failing to do so will kill your plants.

If you still have algae on parts of the home, use your pump up sprayer with the mixed solution to clean faster, wear PPE.Rinse all exterior surfaces if you are satisfied that all algae and dirt are dissolved.
