vinyl siding turning orange in spots

Brandon Vaughn · SoftWash Systems Pro Staff

What percentage mix were you using? I've never ran into siding TURNING orange during wash. You sure it wasn't there before you started and you didn't notice?

Most likely either degraded vinyl that oxidized from the SH and should turn back on its own after a couple weeks. but they really look like hard water stains, especially where they are at the bottom. You might not have noticed them until cleaned. Try a little F9 at at 3:1 ratio and see if it works.

We usually find the degraded vinly on white windows, that face West mostly, and the orange disappears after a couple of weeks.

Siding also installed wrong. You never want to have any kind of siding installed that close to the ground - or even touching mulch. Thats where their foundation should be

This was the orange I was talking about in the other post. If you spray a mixture of oxalic acid on it, it will come off.

I should say, it came right off for me when I sprayed oxalic on right after the orange appeared!

Brandon, I was using less than 1% mix, and thank you guys for the quick response. Barry, where can I get something like oxalic acid from, and what mix ratio is best. thanks

You can get it at some hardware stores or any chemical supplier.

we would try FP Barq first if we saw something like that happen, although we never have.

I have seen this as well. I actually think it may be something in the soil in certain areas. Good advice on the acid, I will try this next time. I have used One Restore, formerly Safe Restore on this before, but that stuff is expensive. Glad to find something cheaper.
Thanks!

Find wood brightener in your local hardware store if you in a jam. Same as oxylic acid.

Yes Oxalic Acid put 4-6oz per/gal of water. it will disappear in front of your eyes.

Barry Landis · Sophmore Member

I agree with Pats mix ratio.

Hank is right on the money with getting wood brightener at any hardware store. i have some F8 from Bob at Pressure Tek.

Michael Derose · SoftWash Systems Certified Applicator

I use 10-12 oz per 1 gallon.

Shaun,

There is a store called The Stain Shop in Linden MI (Flint area). They carry Oxalic Acid as well if you can't find it around you. Shipping from them to you would cheaper than shipping from out of state. www.thestainshop.com.
