[Treadmill]

I accidently spilled some 'De-Lime' (32% phosphoric acid/8% nitric acid) on my cement floor while cleaning the humidifier. It immediately created some white spot which I assume caused some lime in the concrete to dissolve. Is there any product that will remove the white spots? Any help is appreciated.
Don't want to paint the entire floor unless absolutely necessary.

Try baking soda with a little water, a base should neutralize the acid

Not likely. The acid is already neutralized (from reacting with the cement).

Not true. It'll exhaust itself in time but a higher pH rinse to neutralize is always a good idea.

Use friendlier acid than phos next time. A little slower to work but you won't have the potentials for damage like you just incurred. Scale in a humidifier isn't super difficult to dissolve.

Blows me away how people still use hydrochloric, sulphuric, and to a less dangerous degree phosphoric around the house just to save themselves a small amount of time and elbow grease. At least you weren't using hydrofluoric like some idiots in the aluminum cleaning business still do.
