try Rustblast by kbs coatings, used primarily for removing rust from metals but can be used on concrete and other surfaces too....spray on and keep wet, scour a little with a broom then hose off....all rust should disappear. We get well water rust stains on our curbs from watering the grass.

Hydrochloric acid, HCl that would properly be offered as Muriatic Acid at any ironmongery save. Wash the driveway down with a hose first and enable it dry. be sure there isn't any bleach around - they form chlorine gasoline whilst blended!! attempt a small section first it would desire to discolour the pavement and you do not choose to have a humorous formed spot on your driveway. rapidly CLR, if left to sit down down would desire to paintings, yet once you tried that without luck, attempt this. Cheers. superb answer?

I've used muratic acid, available in hardware stores, with great success on rust stains.

Lime away or a "rust remover" from a hardware store.

never ever mix acid & cement products / natural stone, unless you want it eched ( it may be too slick & you need to),
IRON OUT - WHT PLASTIC BOTTLE, RED & BLUE LABEL - MIX W WATER & WARSH OFF...
THAT'S RIGHT WARSH IT!
