    Hard water contains calcium salts, which can cause unsightly white stains on your plain concrete, colored concrete or stamped concrete patio, porch, or basement or garage floor. Although concrete is a very durable material, it's also porous, which makes it susceptible to stains. Many things may cause the salt deposits on the concrete, including water from hoses or leaky flower and plant pots. The recommended methods to fix this problem include Hydrochloric Acid, Trisodium Phosphate, Efflorescence Remover.

    Hello. I would mix 50/50 of vinegar and water in a spray bottle. Then spray it on heavily and let it sit for 5-10 minutes. Then use a scrub brush and scrub. Repeat if necessary. Then mop the floors clean.

    I would use a gallon of vinegar and a gallon of water in a bucket and soak hand towels to lay over stains, so it stays wet. Wait an hour, then wipe up. Vinegar won't hurt the towels, just rinse them with a hose, wring out and throw in washer. The longer it stays on the easier it comes up.
