NO ! All the acid does is modify the pH, hopefully so the chlorine can do it's job.
How are you going to wash the concrete to get rid of all of the acid? If you don't get rid of all the acid, paint is not going to stick.
Try a mixture of 75% water, 25% muriatic acid (hardware stores). [wear protective gloves, googles, boots]
When using Muriatic Acid it's important to wear the proper protective gear, and have plenty of clean water on hand in case of an accident. Always pour the acid into water, and not the other way around. Wet the stones before cleaning. Dilute the acid with water. Make sure the stones are soaked with water before applying, and don't leave the acid on too long. Scrub the stains with a scrub brush. Rinse everything off, and allow to dry.
It should work, Try a small test patch before getting over comitted however.
I this might be your problem. Hard water deposits can accumulate on the sides of the toilet bowl. Then if you clean the toilet using something like Vanish, which turns the water blue, it can cling to the mineral build-up on the bowl. Kohler does not recommend using Vanish. To get rid of these stains, you can try some muriatic acid (diluted of course.) You only need about a 10% solution. Be very careful so you don't burn your skin or eyes if it splashes; wear rubber gloves and eye protection. The brush you use with the muriatic acid should not have any metal that can come in contact with the acid in the toilet. There are brushes available that do not use heavy wire to hold the bristles. A good cleaner is Zep available from Home Depot. This is a good alternative to the muriatic acid.
