Cleaning white vinyl post & beam style fence

[Donald]

We have some sections that are under trees and get black mold & mildew. There are a row of bushes planted next to the fence.

Electric pressure washer got it 50% better but it's no where near "clean".

Spraying a bleach solution would damage the plants.

One suggestion was vinegar and water applied with cloth. Need to try

On another section I have tried one of the "Wet and Forget" products that works over time and is ammonia based.

I have gas pressure washer if all it takes is more PSI?

The Wet & Forget products would be the easiest. I can paint it on with a foam brush and not get much on plants But wife will not want to wait months for it to work.

Other ideas?

I've never seen a bleach solution harm plants...well maybe bleach flower petals but no permanent harm .

Rubber gloves, bucket 'o bleach solution, coarse toweling (those blue ones doctors use to clean road rash incidents) rinse.

I think you're at the 'elbow grease' stage. A foam cannon won't do it unless ridiculously powerful chemicals are used.

When I clean the same items, I wet down what I want to clean, Then with a soft bristle brush on a stick I scrub it with a 50/50 solution of water and bleach. It comes off super easy and the bleach leaves enough residue, to prevent it growing back for the rest of the year. I haven't hurt the grass or plants arong where I cleaned yet.,,,

Wet the plants in question first, keep them wet while working. A 50/50 mix of bleach and water applied and washed off with the power washer after about a 10 minute soak should get the job done. Once compete rinse all plants and the fence with water.

I use a gas powered (3100 PSI) on the never ending vinyl rails
that are on the decks/stairs of our house on piers.
Never had an issue with removing any mold or mildew.

No one has mentioned the ammonia based Wet & Forget products??
