I'm quoting large roof to be cleaned. Any ideas on cleaing the rust from chimney flashing that has gotten on the stucco. There are 2 chimneys and this is the worse.
One Restore Eaco Chem. Pre wet those shingles really well, then follow your run off with water and water and soap.

Rust that derives from iron oar in water like irrigation rust is easily cleaned with a light acid solution. However.......
Rust that derives from rusting metals like,
Flashing Cars Patio Furniture Feet BBQ Grills Chimney Caps and any other metal piece that is left on or around a surfaces...
These stains are often not removable. They can be lightened with chemicals and or completely removed with soda blasting or downright sand blasting. The issue when you get these rust stains on a surface like a shingle roof is that the cleaning method will often damage the shingles / surface. Acids and other chemicals like degreasers can not be used on shingles in any great concentration because they will break down the petroleum in the shingles causing the shingles to literally come apart.
The recommendations above are good ones in moderation. Don't go crazy trying to get a 100% result!!! Be completely satisfied with a 30 to 40% effect.
Use the utmost of caution and remember that some stains are impervious and we can not reverse ageing.
Hope this helps,
AC

Help,
I sprayed F9 rust remover on a high school to remove the irrigation stains. The stain was removed. But when I returned to take the after photos, the brick had a white haze to it. I called Craig at F9 he told me to go back and rinse the area and lightly scrub the area and rinse again. The white haze seem to get brighter as you can see from the after photo.
Any suggestions on how to remove this white haze?
Not sure if the outside tempturature would make a difference. it was 37 degrees
Thank you in advance.

No I rinsed with a 5 gallon bucket of warm water. I used the portable pump I bought from Paul at SoftWashapooloza. It's the same pump we use for the green wash injector.
I was going to try to powerwash it tomorrow. What are your thoughts?

If a pressure washer dosent work the try a light solution of hydrofloric acid. Its the same stuff you can get at the landscape store. Efflorescence cleaner.

Try a light solution with a pump up sprayer. Let sit for 5-10 seconds then rinse off.

Do a small spot first. Also try white vinegar also. I would try the vinegar first.

Mix up some soapy water, like Dawn, GW may work, spray it on, agitate it in w a broom or brush, and then lightly rinse w a pw'er. Always prewet rust stains and then rinse thoroughly after using any rust remover product w acid in it. Good Luck

Hey Craig,
No I haven't been back to powerwash it yet. Still a little cold here in Michigan. I did go back and scrubbed it with a brush, while it was dry and that did remove some.

Thanks for asking Craig
