paint or acid etch
Yes, vinegar can potentially etch glass if left on for an extended period of time. It's acidic nature can eat away at the glass surface, causing dull spots or etching. It's best to avoid using vinegar on glass surfaces if possible.

Usually when you're planning on going over it with additional concrete or cement, or in preparation for an epoxy or waterproofing coating.
I'm not sure what you mean by 'safe', but vinegar can etch aluminum - so I would not recommend leaving vinegar in an aluminum pot overnight.
To etch concrete for a decorative finish, you can use a combination of acid etching and staining techniques. First, clean the concrete surface thoroughly and apply an acid etching solution to create a rough texture. Then, apply a concrete stain or dye to add color and depth to the etched surface. Finally, seal the concrete with a protective coating to enhance durability and longevity.
Vinegar and water. Never use paper towels or newspaper. It will etch the circular movements right into your windows.
To effectively etch a concrete floor for a new finish, you can use a concrete etching solution or a mixture of water and muriatic acid. Apply the solution to the floor, scrub it in with a stiff brush, and then rinse thoroughly. This process will help remove any dirt, grease, or other contaminants from the concrete surface, allowing the new finish to adhere better. Be sure to follow all safety precautions when working with acid-based solutions.
To apply concrete etch to a surface, first clean the surface thoroughly. Mix the etching solution with water according to the instructions. Apply the solution evenly using a sprayer or brush. Let it sit for the recommended time, then rinse it off with water. Finally, neutralize the surface with a baking soda solution and rinse again.
You can't make it. You used to buy Etch Bath and use a marker to fill it up in, if you can find it still you can thin down the etch using vinegar (too much will lower potency though). Make sure to wear protective gloves and eye protection as etch can cause horrible burns, tearing of the skin, and pretty nasty chemical scars. You used to be able to get Etch Bath from stores like michaels and Joanns and Hobby Lobby etc. but now theyre all gone, assuming from theft and liability reasons. If your looking for a better alternative they have glass etch already in a graffiti marker (mop) on amazon by searching "graffiti etch" no work, or risk in injury and work great.
Alkaline cleaners are generally more effective and safer for cleaning concrete than acid cleaners. Acidic cleaners can etch and damage the surface of the concrete if not used properly. Alkaline cleaners are better at breaking down oils and grease commonly found on concrete surfaces.
If the water's chemistry is not correctly balanced, it can. For example, if your pH is too low, the water can etch cement you'd materials.
