Help! White siding got stained after I cleaned it

Just re wash the house. Remember when you rinse the water should be falling


Re washing the house won’t do anything.

Just leave it be for a week.

The answer isn’t always throw more bleach at it.

No need to to rewash. If driving you crazy a magic eraser will take the leaker right off.

I use f9 for fallout removal as i didn’t have any luck with degreaser getting it off at least where I’m at.

I understand this is your moms. Are you telling me you would leave a customers house like that for a week. No way re wash the house rinse it the correct way all your problems will go away

Have you tried wiping it with a rag?

If you read the very first post he said he tried using sh again and it didn’t work. He even tried it at full strength.

@marinegrunt I apologize I should have asked him what his house wash was and what strength his bleach was first. I assumed he was at least a part time pro. Thank you now he can clarify. If it was me I still would rewash the house. But I would be doing it with my house wash recipe that’s why I told him to do it.


Yessir. Rag works most of the time but you do get the stubborn ones sometimes

Don’t wipe it. If that side is oxidized it will look terrible. Maybe not more terrible than the brown streaks. If you can, do what @Patriotspwashing suggested. Let us know what it looks like in a few days.


Do you use something else in your house wash mix that most don’t that would be able to get the stain off?

If I didn’t have this forum and it wasn’t my mother’s house, I’d be out buying every detergent at Lowe’s or HD and trying it. But someone recommended giving it time to see what happens so I was following that advice.


That was the second thing I did after trying to rinse it off with water.

It’s a reaction with the white old siding and the SH…

Just leave it, let it go away.

Spraying more chemicals on it is not going to fix it.

My strength bleach was 6%. I used Dawn soap as my surfactant (I know I’m not supposed to use soap but I still haven’t figured out why exactly–even with all the posts I’ve been reading. And another site had a few people actually recommending soap.)

I considered myself a part-time pro until I found this site. Sheesh, now I’m not even sure I’m a semi-pro.

I’m still learning. I take great pride in my work which is why I’m on here reading and studying. This forum is a God-send. So I’m totally open to learning and fixing where I’m falling short.

This is the surfactant that most use.

Also, save some money and buy liquid pool shock. Bleach is called Sodium Hypochlorite. Liquid pool shock is 12.5% Sodium Hypochlorite. Twice as strong as household bleach at about the same price. You just dilute it to the strength you need. You’ll eventually graduate to buying 55 gallon drums or 275 gallon totes.

Yes, thank you! I shouldn’t be calling it bleach. I’m a newb. SH it is. I called around a few days ago to all the pool places in my area and only one place sold 12.5%. Thankfully, it’s about 15 minutes away. I still had a small stock of 6% SH so I decided to use it up.

Brown stuff

What’s the shelf life for this stuff? If I’m only doing a few houses, will it last more than a few months?

Yup. It’ll last a while. Just buy a gallon if you don’t do many houses. Mix about .75-1oz per gallon of house wash mix.

Thanks! Seems like it’d be way cheaper to use this than to use Dawn or other soap!
