  • Is your porch enclosed or outside? Adding a couple of pictures to your question would be a good idea please. – Criggie Dec 29 '18 at 21:35

I had black mold in my sunroom, and my solution was to hit it with bleach (mixed with water), then to scrap it off and remove it from the areas. I then hit the area with "Mold Control" from Home Depot (as it helps also prevent the spread of mold. I did this to the effected area plus 1m on either side. Then I painted over it with a mold-proof paint (talk to people in your area who can best advise stuff for your region and colour).

I hope this helps. But importantly, use proper PPE use a mask that blocks that stuff and googles! Be safe man!

I'd nuke it with either the pressure washer or some bleach, depending on the surface.

  • Which surfaces would merit what? – ThreePhaseEel Dec 29 '18 at 20:22
  • If I thought the pressure washer would damage it, I'd use the bleach. Pump spray a bleach solution followed by a brush then rinse. If I think the bleach would ruin it, I'd start with soap and a brush. – Gary Bak Dec 30 '18 at 1:08
