Jeremy,
Your worst case scenario rust and acid stains are fertilizer rust stains and [URL=“http://www.front9restoration.com/fertilizer-rust-stains-on-concrete/”]battery acid stains.
F9 should be diluted 1:2 (1 part water, 2 parts F9) for these. A case of 4 gallons makes 6 gals of restoration cleaner at this dilution. So at a minimum dilution this will be your strongest mix.

How heavy should you apply the 1:2 ratio and how many applications should I use on fertilizer stains? I got a driveway that has quite a bit of fertilizer stains I want to get out.
Thanks for sharing your pics Brett. I hope your customer was happy and you got paid.

Looks good. What was your mix ratio
.
Just put some on a microfiber straight from my sample. As easy as it came off im sure 1:1 would be fine also.
Yea she was… Have you got any feedback from anybody using rust remover + on fertilizer stains? I was thinking about trying some for my upcoming job but my sample’s about out and I didn’t want to buy a bunch and it not work…
Hey Bret, we have actually had quite a bit of feedback for Rust Remover Plus for use on fertilizer stains and we have heard nothing but good things. Your pictures look great, thanks for posting them up.
Trey, can you send me a sample?
yes sir John will do
This is some top notch stuff!!!
make sure you don’t use it straight on concrete it will etch it and it did not work on my fertilizer stains!!! I gonna get several gallons of F9 to try to get the fertilizer stains out because it looking like that’s the one thing that should get it out…
Brett, sorry you had trouble with fertilizer rust stains. That is actually what we have had the most feedback on and seen the best results with Rust Remover Plus. I would be interested in talking with you more about your successes and failures with our product. We are always looking for feedback good or bad to better improve our offerings. Thanks.
Headed to a patio job right now. Gonna give it a try. Got your sample Monday. Thanks, Trey.
Make sure you have the new MSDS for F9 on hand. Also make sure you’re using proper PPE.
PPE is important for any kind of rust removing job involving hydrofloric acid - whether that be F9, Rust Remover Plus, or any other product.
