Muriatic acid stains on stainless steel
adv.
By mistake yesterday I splash with the mop a few drops of
muriatic acid
solution (water diluted) on the freezer of a house we were repairing the grout, we didn't notice the accident until today that the owner of the house call us a let us know she have small yellow marks on the stainless steel door of the freezer. What can I use to remove those stains?

Fine grain steel wool, work with the grain/finish. The stains shouldn't be too deep (you can also use brillo pad).

DO NOT use steel wool or Brillo Pad unless you want to have a rust problem.
Use only a NON iron containing material like Scotchbrite(TM) or fine grain emery paper or the like.

We are remodeling our home and have just discovered what we think are tiny acid stains in our brand new sink. They are numerous, tiny and appear to be pitting the surface and have not come out with the usual commercial products available.
What can you suggest as a next step?

I've had experience removing muriatic acid stains from stainless steel. A metal finishing specialist once told me to use "Barkeepers Friend", a cleanser readily available in stores, with a cloth or sponge. It's non-invasive and is the best first step. I was amazed how well it works with a little elbow grease and a few applications. I've used it a couple times without the need for abrasive pads like emery cloth or sand paper. These would only be second options as they can change the grain of the finish. Spread the word. It's a little known secret that works.

I sprayed my gas stove with Mr Muscle kitchen Cleaner, became busy with some other work, went out on errands and forgot all about it till I returned home late at night! I was shocked when I went to switch on the gas to find it all stained. I tried CIF, more Mr Muscle, plain soap and water - and even ash! nothing worked - the stains make the stove look so dirty - please help someone and tell me how to get the shine back!

Stainless steel kick plates on mahogany-colored wooden doors look impressive in any business setting, until floor finish or stripper from adjoining CVT or seamless floor covering is accidentally splashed onto the bottom of kick plate. Cleaning crew tries Windex, which has ammonia, and leaves all kick plate shining except for the bottom that is stained. Keep working on the panel and eventually it takes on brownish streaks with or against the grain. Seemingly the more the panel is wiped, the worse it gets. Brownish scares me. Makes me wonder if it is starting to rust. Had a similar problem with grab-bars in hospital restrooms. Everything had to sprayed or wiped with a germicidal cleaner/disinfectant for infection control. The product does a good job killing germs, but it also kills the luster of the stainless steel grab-bars. First little brown spots appear. Is it possible that stainless steel is not always stainless, or can those brownish stains be worked out? I saw an empty Mineral Shock bottle sitting around somewhere. Would that item possibly be on of the suggested cures, and worthy of purchase?
