I have tried everything on this cast concrete facade. When I say everything I mean, Rust Remover plus, straight 12.5% SH, oxalyic and high pressure. I can’t make a dent in it. Any suggestions are greatly appreciated. I forgot to mention that there is a gutter splash guard just above this so it may be coming from the roof but it’s not rust or organic. ![Brown%20Stain](https://pressurewashingresource.com/community/uploads/default/original/2X/7/780161474d5bcad4df506cdb7ff09a0482ce4a7c.jpg) ---

I’d try hydrofluoric acid That almost looks like phosphates, which are basically tea stains, you could try a phosphate remover, I’ve only used that in pools though You could also try tile and grout cleaner, or clr Tricky tricky ---

Thanks for the ideas. I also tried an Efflo remover just because I had some. I’ll look into the phosphate remover, anything in particular you’ve had success with? ---

Send pic to Craig Harrison and your comments on what you’ve tried so far. but I’d start with F9 Barc mixed 1-1. Spray lite mist coat 1-3 times over 15min. Don’t let dry. Can use light agitation. Repeat if necessary. ---

In all honesty, I can’t remember. I probably ended up using One Restore on it but I’ve killed a lot of brain cells since then. ---

OneRestore works on a lot of stains and surfaces. Great stuff. ---
