Muriatic acid is not the first choice for masonry cleaning but the last resort.Muriatic acid is a highly reactive liquid acid, and one of the most dangerous chemicals you can buy for home use. It is an industrial-strength solution of hydrogen chloride gas dissolved in water, also known as hydrochloric acid. Yep, muriatic acid is "super stomach acid"! With the exception of some plastics, muriatic acid can damage most anything it touches, including clothing, metal, and skin! It emits a suffocating odor that can quickly burn the lining of the nose, throat and even the lungs. Typical home uses include heavy-duty masonry cleaning, preparation of masonry for painting or sealing, removal of efflorescence or mineral deposits and pH reduction in Swimming Pools. Its reactive power makes it the chemical of choice for some types of masonry cleaning. Muriatic acid is sold in a standardized concentration of 31.45% acid and 68.55% inert ingredients, primarily water. This is the concentration you are going to find in your local hardware store. Our mixing suggestions are based on this concentration... if the muriatic acid you purchase is stronger, adjust the dilution proportions for the job accordingly. A short anecdote... A hardware store in my area stopped storing muriatic acid. Over a period of years, gaseous seepage from the old containers had begun to dissolve the metal shelving it was stored upon, as well as the metal containers of other products nearby!

Can you stain concrete with wood stain?
Yes you can use wood stain on concrete but it will not penetrate the concrete, it does look nice and you can use different shades together. To keep the stain on it use a concrete sealer in a couple coats, it will give it a shiny wet look. I have tried it with fake wood only because where I live I can't get concrete stain. And it looks great.
Will strength of concrete mix will decrease if hot water is used?
As long as the water is liquid, the strength of the finished product will not be diminished by the water temperature.
Does ketchup stain car paint?
There is acid in the tomato so if it is left on for very long, there will probably be a mark.
