Pressure washer cleaning fluid. Will it kill my plants?

I'm going to be painting my house next week, and I need to pressure wash the exterior. My question is will the cleaning fluid that goes in the pressure washer kill my plants? Most of them say they are biodegradeable on the label.

I don't know what you will use, but typically one uses bleach 25% in water with some Tide to spray on the house before pressure washing a house. Rinse plants around the house before and after you apply the cleaner and the plants will be fine.

Just because something is biodegradable does not mean it won't hurt the plants. After all 2-4,D and other herbicides are biodegradable.

Hope this helps.

Personally, I never ran any chemicals through my commercial pressure washer.
As mentioned I always pre-sprayed with stripper, brightener, or oxalic.
If you pre-spray a section at a time, the chemicals will have a better effect.
Cover any plantings you do not want to harm, or rinse very thoroughly.
And as Norm says, "And don't forget to wear these, EYE protection" .

Thanks for the advice. I don't think I'll put any chemicals in the pressure washer.
