Best way to get mold off stucco when bleach didn't work?

I have mold on the outside of my home from all the rain this year. I tried to put bleach in a spray bottle but had no luck.

    go to home depot rent a pressure washer and ask the associate for the right solution to use.

    I used a tilex type mold shower spray product with a nozzle spray that had a jet / stream setting on the bottle and sprayed the moldy area. I waited about 30 minutes then used the hardest jet setting on my hose and all the mold just vanished from my stucco and hasn't returned.

    If bleach didn't work, head to the hardware store and ask there is a product that kills mold and up to a year. I use diluted bleach and it works great. Have you tried vinegar ?

    If the outside of your house is wood, javex will not kill mold on porous surfaces. Wood is porous. It only works on hard non-porous surfaces. Baking soda and vinegar should work on wood and kill the mold as effectively as using Javex on hard surfaces. Just pressure spray after and then treat with Concrobium Mold Control Spray (Home Depot).

    there is a product called Wet and Forget safe for all surfaces. Do not try power washing it will not kill the mold.
