Vinyl siding vs. mold...

Hello all -
Why is it that houses with vinyl siding seem to get buildups of algae or mold on the vinyl?
I don't see the problem with wood or aluminum siding. This old house I'm in (1911) still has its original stippled wood siding (I -think- it's wood, have wondered if it could be asbestos-based). The paint is at least 34 years old, but still -- no mold.
Yet that stuff takes to vinyl like it belonged there. Any way to keep it under control (other than washing or cleaning it off)?

Never noticed it. My house has vinyl siding and while the foundation on the north side has had some mold, the siding above it never has. Never took any preventative measures either. I may wash the house down every few years if the rain does not do enough, but that is all.
Spray it down with a solution of 1/3 vinegar and that will kill any mold spores. Strong bleach should not be used.
Trim any bushes and tree branches nearby too. Darkness and moisture make a comfy home for mold.

My house has vinyl siding, and the north side, which is also very shady in the summer, does get a little green mold. I just wash it off with some bleachy water every year or two.
What's wrong with bleach in this situation?

Strong bleach or undiluted bleach should not be used. Diluted should be OK. I'd go with at least 8 qt of water for every 1 qt. of bleach.

I use a product called Jomax House Cleaner and Mildew Killer
Mixing instructions are:
3 1/4 quarts Water 2 1/4 cups Bleach 3/4 cups Jomax
It works very well on the mold I get on my vinyl siding. Spray it on, let it sit a few minutes, hose it off.

I've got it on aluminum siding on North side of house. Easy enough to wash off, where I can reach it, and a little dilute bleach will not hurt but in shaded sections it reappears.

I got the Vinyl Mistake for my first time ever 7-years ago and just spent painting efforts to clean it back to new, 2-years after it got so bad. No, hosing it off annually did nothing in avoiding the mess it turned into. I wanted the personal experience.

It's actually funny to see you so clearly note in your question exactly how environmentally and owner FRIENDLY NON-VINYL has been, just to STILL see the ABSURD answers you received. UNBELIEVABLY, not a single answer agrees with you and only and specifically tries to disprove you.

Well, I positively AGREE WITH YOU and your very astute assessment. However, I cannot AT ALL agree with ANY of the other EXTREMELY POOR "answers", they ALL pretend that they've never had anything but "PERFECT-FROM-THE-START" vinyl since birth...laughable.

Well, that's why I waited and got vinyl DECADES after its RIDICULOUS inception. Mine is top quality and touts, even in warranty, that it has fixed ALL of the common problems-of-old with vinyl siding. Though, I still find that it DOESN'T wash itself in the rain AND that YES Aluminum, Steel, and Wood beat vinyl in most every way that even applies to probably 90% of vinyl owners.

Must live in a mold infested swamp with all of that.
My house was build in 1978. I do wash it with a hose very couple of years to get the dust off of it. I've been here 36 years and in all that time I bet I have no more than a few hours in maintaining it.

And despite being told nicely now many times, iggy still refuses to quote anything he replies to, so people can follow whatever 10 year old thread he's dug up today to bitch about. I still think he's probably a shill for HomeMoanersHub.

Sure they display chronologically. You just replied to the oldest post and then to Ed. We then have to go scrolling around to read those posts. Almost everyone else replies with quoting the part they are replying to so it's right there. And also, since many of these are long posts with many points, if you quote what part you're talking about, or reply after select points the other person made, it's much easier to follow. And I'm not the only one to have told you that either. Very few people just post without anything preceeding it as reference. Look at Ed's post for example. He quoted what he was replying to. And you still don't understand that your website is just a portal into Usenet, that AHR is Usenet and you are posting on Usenet.
Now maybe you can explain something to us. How is it that you keep finding these old posts from 5 and 10 years ago on a variety of subjects and reviving them over there? Like what exactly is the process? ARe you looking for them? Do they pop up there for you and say "what about this thread from 2005?"
at that website?

See, I know how to do it and know what I'm doing...I used to be on Usednet back in the beginning. It sucked then and is still the same suck, but now it swallows.

That's all just from a website that's organized by commonalities, very normal and straightforward. Both, new and old are readily right here for me to twist the knife whenever I want...I've been very kind.
