Good evening to you also Kathy.
I do have a household hint. Cleaning the outside of the house and areas that get moldy. I take a garden sprayer attached to a hoseand fill it with bleach. The mixture comes out 50/50. It is much more powerful in this form than straight bleach. Let it sit awhile to work and then repeat the proscess if needed. Rinse everything afterward with just water. The bleach does not harm anything to my knowledge. I’ve used it for a number of years.
That sounds like a good way to get the outside cleaned. Good hint.
