re: Pressure washing help needed

I use a combination of JoMax and Outdoor Bleach, diluted with water. I apply with a garden sprayer to avoid the bleach causing and pressure washer pump seal problems.

I only let the solution set for 5 or 10 minutes. Don't let it dry on your siding. Wet down any landscaping or grass next to the house before spraying the cleaning solution.

Have fun!
