How can I clean rust off of vinyl siding?

Try Zud...it's a powder..make a paste and gently rub it on, let set...rinse

There's a product "NAVAL JELLY" that i've used in the past that neutralizes rust on metal. Give it a try. I'ts amazing how it removes the rust without harming the parent metal. I'ts available on the internet. Good luck Mac

Thank you! I will try that.

Try CLR. It took shoot off our stone fireplace.

Coca Cola ...then Rinse the Acidic Coke off or C. L. R.

I used greenmachine cleaner spray. Rinse thoroughly. Don't use bleach...it will BOND to the rust.

try baking soda and tooth past let it sit then rinse

also wd40 works well on rust
