For anyone interested in the TRUE HCl concentration of muriatic acid (sans WIKIfication) simply Google "muriatic acid msds" and you will see that, while the concentration varies by manufacturer, it generally ranges from 33-40%. Furthermore, even if you order HCl by name from a chemical supply house, you order by concentration, usually some reagent grade, with fuming HCl starting at ~40%. No hardware store in the world sells 100% HCl for etching concrete.
DANGER / SEVERE HAZARD -- Muriatic Acid IS UNDILUTED (100% concentration) Hydrochloric acid.
Wear Eye and face protection, acid resistant gloves, rubber slicker suit, or be VERY careful as Hydrochloric acid is highly corrosive and can instantly burn holes in your skin and tissues, and right through all woven clothing.
When diluting ANY acids, it extremely important that you NEVER ADD WATER TO ACID, as the reaction between the two will result in an "explosion" throwing acid instantly in all directions.
The PROPER method of diluting acids is to very SLOWLY pour the concentrated acid into a larger volume of water.
For an additonal "layer" of safety, do not pour the acid from a large and heavy container, as it is more difficult to handle and control. Pour the needed amount of concentrated acid into a smaller, acid resistant, container which will be easier to handle and therefore control the pour rate.
When using baking soda for neutralizing acid residues, be VERY CAREFUL to NOT ALLOW the baking soda to contact the UNDILUTED ACID as the resulting reaction can be explosive!
1Bust out some protective clothing and a gas mask. Have a good supply of fresh water on hand in case you need to rinse any body parts.Be very careful with muriatic acid; it's 30% hydrochloric acid, and is fairly hazardous.
If you only want to barely 'etch' a slippery concrete surface, it is best to dilute the acid with water, as acid straight from the bottle tends to be very aggressive with any concrete surface, and can badly damage the surface very quickly.
For a deeper etch Pour the substance where you want to etch the concrete and spread it out with a nylon broom. let it sit for a half-hour. Wash it thoroughly with the hose after.
I have used a small hand held spray bottle set to a fine misty spray, and skipped the 'rinse' step altogether with very good results.
'Baking Soda / water solution' is an acid neutralizer, and can be used around most landscape with safe results.
>>> Get used to the process FIRST. Buy a few cement blocks, bricks, or slabs that you can throw away. Different concrete blends, strengths,... react differently. New and old concrete of the same formula will also react differently. An new slab poured next to the exact same mix from the same company in an old slab will be different due to moisture content and curing time).
Good luck.

Can you power wash concrete?
Normally you can with no problem, however if the concrete is in bad shape it may blow chips from the top coat. A mixture of muriatic acid of 4 parts water to one part acid will make the cleaning a lot easier just dump it on the concrete and let it bubble for 10-15 minutes then wash it off with the pressure washer but if you never handled muriatic acid be very careful it will burn you. If you have a lot of plant life near the concrete your cleaning you may not want to use the muriatic acid

Can you clean your patio with Muriatic acid?
Cleaning your patio with Muriatic acid is generally not recommended. Your patio may contain stone, concrete, or wood. The Muriatic acid is likely to eat into those.

Still, if you are determined to use Muriatic acid, have a respirator ready, wear gloves, and have a bucket of lime ready in case you drop something.
Can you use white distilled vinegar to etch concrete?
Concrete is very hard. To do any good in etching it you need something very strong. Muriatic Acid is the only thing that I have found that works. How strong you mix it depends on the concrete. Some concrete that was poured with a lot of water in the mix will need less Acid. Concrete that is smooth and hard will take more. Muriatic Acid is caustic. Read the direction. Use rubber gloves; safety glasses; and a respirator. For a large project, such as a driveway or Patio. Use a plastic garbage can. Fill with 10 gallons of water. Carefully pour one gallon of Muriatic Acid into the water and mix with a wooden paddle. Take a plastic watering can and fill it with the solution. Wet your concrete with a water hose, then carefully pour the Acid solution onto the concrete. It will bubble and foam. This is the acid etching the concrete. Let it set for about 15 min. Scrub with a stiff push broom, and then rinse with a water hose. The acid will kill plants and grass. Steve Schillinger sds@knology.net = Safety Note = Make sure you put the water in the garbage can first--adding water to acid is a sure way to get splashed with concentrated acid.
