^ I power wash my house, yard and driveway yearly after the rainy season, 95% of the paint stays on, the ~5% thats comes off gets touched up, I standby what I said, if the paint comes off by just washing it, the paint had never adhered correctly in the first place, it is a crappy paint job! my mid-priced Psi washer which I would guess has about 1k nozzle Psi is not capable of stripping paint off if it is a acceptable coating, sure I could buy a high end Psi washer with 35k nozzle Psi that would strip paint off a car, but we are talking about cleaning mold which entails washing walls drives etc, you should be able to do so without the paint coming off.

Cheers

Power washer or plain bleach just pored on will do the job. Dont need to scrub anything
