I use a cup of powder laundry detergent, big squirt of dawn dish soap, and about 2 cups of pool shock (12% bleach) mixed in a 5 gal bucket with water, then feed into the pressure washer soap injector. Spray it on, let it sit for a minute, and hose off. Do not need high pressure to rinse, which is good.

You can mix regular Dawn liquid dish soap in with the solution to get extra cleaning power. Regular dishwashing soap will do a very good job of cleaning vinyl siding, but if you mix it with the Stain Solver, you’ll end up working much less.
