    Be Careful. use a diluted solution of Muriatic acid. It is very caustic so be very careful and follow directions. Also Lawn fertilizer is not good for bare feet (little ones?). Try to go organic whenever possible.

  • CLR (Calcium, lime, and rust)

    • Oh no! They also make a toilet cleaner, it's very thick, designed to stick to vertical surfaces. You might have better luck with it. Other than that, if go with johns idea. Muriatic acid might kill your lawn though, that should be last resort. Clean up with baking soda to neutralize. Good luck!

    I do not know what products you have used but you might want to try spray paint remover on it let it soak then brush on it and rinse it try a spot at first then clean up water with rags? I don't understand the orange spots where that came from.

      I used Scotts Max green in 3 days fertilizer. When I used my spreader some of the fertilizer got on my sidewalk and driveway which I did not see. it rained soon after and the orange spots appeared.
