    Hello there, Where outside the house? If on the walls etc. Use Spray and Leave (available from DIY's and online) and follow the instructions.......On the soil?

    Bleach and water scrub with a brush if realy bad let bleach sit about 20 min then hose off if you could power wash it off with a piece you put on the end of the hose

  • There is a product called "wet & forget" that everyone raves about. I have never used it.

    High pressure hose. Or can grab a nozzle used for car detailing in the vial it comes with fill with toilet bowl cleaner the nozzle will mix water and toilet bowl cleaner together spray unto the house. I let it soak in for about 5 to 7 minutes if your car detailing nozzle comes with a brush attachment you can use that with water coming thru it..or just use high pressure nozzle on your hose if shhhmagma is still holding on grab a broom swipe it over to loosen troubled spots, spray to rinse

    There is a product at every hardware store for cleaning the house. It is awesome. Hooks to the garden hose and does a great job. I think Wet and Forget is for showers in the bathroom. Good luck.
