Polished stone amazes me when it comes to the size of kitchen counters. Jewelry seems like it would be less of a challenge and can be done with something like a Dremel Tool. I bought a special vice for sharpening knives. It came with four grades of diamond grit bars. I think the first one is 200, or possibly 100 grit, but the last one is 600. That last one doesn't seem like it would do anything at all, but as you say you can even go to a finer grit than that. It sort of makes sense on mental. It's just hard for me to wrap my head around the fact rocks can be polished the same way.

I never worked with Terrazzo, but apparently it's mostly rocks of one kind or another. At the old house we had a walk-in shower installed. They used some kind of poured walls to build it. Might have been Terrazzo. It looked amazing in any case.

Many stores and schools had Terrazzo floors in them. Telltale was the aluminum dividers between the sections.

I had a couple of Thumlers Tumblers over the years, an AR-1 and an AR-2, it think they were, but ended up making a couple of my own much larger from old steel steam mainline pipes we had laying around the greenhouses junk areas.
I feel they worked better than the store bought units, and definitely lasted much longer, hi hi.
I used to pick up interesting rocks all the time, usually they were some type of quartz, but sometimes I ended up with some really neat ones after they were polished.
The final polish was usually done with aluminum oxide, and worked quite well for that lustrous shine.

The only thing I now about aluminum oxide is that it is impossible to remove from pots and pans. LOL What I have seen is black and ugly, and there probably are a few other elements mixed in with it. Aluminum is crazy stuff. It can be made bight and shiny, but once it oxidizes, the game is over. I haven't found a way to get it clean and shiny again.

I'm sitting here chuckling over your aluminum fiasco's.

Aluminum Oxide is only used for polishing stones and a few other aggregate surfaces.
Here's a little article from a store who sells it, and better grade things.
https://rocktumbler.com/polish/aluminum-oxide/

About the best thing to remove oxidation from aluminum is Vinegar, then rinse and polish.
I normally use Wenol as the polish, but Silvo (not Brasso) does an excellent job.
If you want that mirror finish, you can buff aluminum with Jewelers Rouge, then clean and wax.
Alternately, you can buy products like Star Brite, which is often used on aluminum tank trucks.

When using Vinegar, work in an area, then rinse, else the Vinegar will also cause more oxidation.
Keep it wet with clean water until ready to polish.

I've not heard of Wenol until you mentioned it. Apparently it's popular stuff in the restaurant business. I don't have a lot of aluminum or stainless cookware, but a couple of the items could use a good polishing. There is a drip pan that I use in the air fryer which seems to be aluminum and I never was able to clean it properly from day #1. I use vinegar and baking soda all the time, but all it did to this drip pan was spread the gunk around to make it look even uglier. Fortunately, nothing edible ever sits on it so that being ugly and oxidized isn't a problem. The fry pans, however, are different. I am putting all my faith and confidence into your good judgement and purchased a couple 100g tubes for $24. It was the best price I could find but not sure it is the cheapest. I ended up getting it from E-bay which promised to deliver it 'free" by the end of the month. Amazon, who had it for the same price and free delivery, could not get it here before December 14th. Interesting how that happens.

Were you in the service? Wenol is what we used on all our brass buttons, hi hi.
I always have a couple of tubes of Wenol around the house and in my office.
All I have right now is the Wenol Red their normal one.
But they do make Wenol Blue as well. I forget if it is the one with abrasives or the one for silver.
Regular Red Wenol does not have abrasives, which is why it is suitable even for hi-tech lab equipment.

I'll guarantee you won't be disappointed in the Wenol Product.
I get the 100 ml tubes distributed by Rickitt Benckiser from a religious group called Arise & Shine.
Unlike Brasso which can scratch mirror finishes, Wenol does not. You'll love it!

No, I never had to polish any brass, but I did make copper clad pots shine at one time. We had a set of Revereware pots that basically were stainless steel with a copper plated outer bottom. Any heat applied to that copper during normal cooking would discolor it. I don't think it affected the ability to cook in any way, but it did look less than attractive when the pots were hanging on the wall. There were a lot of remedies suggested; I think lemon juice and baking soda was one. Those that did work required a lot of elbow grease, and the original shine was hard to duplicate. Then one day mom found some copper cleaner at the store. It looks a lot like kitchen cleanser but was specifically made for copper. It was amazing stuff whatever it was. Just dust the bottom and spread it around with a damp sponge and it all looked like new.

The Wenol I ordered comes in a red box, and I did in fact see one or two ads for the blue version. Red is by far the most popular. LOL The two tubes will probably be a lifetime supply in my case, but the satisfaction of having bright shiny pots will be the best payback.

At one time, the Original Bar Keepers Friend did an excellent job on Copper.
I also had one, don't remember the name of it anymore, that said Copper Cleaner and Polish, with a warning that it was ONLY FOR COPPER.

I have a tube of Wenol in my office, and another in my night stand at home.
After like 5 years they are both still half full. But these replaced the two tubes I bought when I first moved down here.

When Debi's mom was alive, she had all kinds of nickel lined copper molds hanging on her kitchen wall. She would clean them, but they would tarnish again fairly fast. After I did them with Wenol, they looked new and stayed that way for years.
After she passed away, all the copper wall items went to Debi's sister, and then to her niece.

I didn't discover Wenol until I was in the service. It was one of the only items allowed that were not government issue.
Heck, we couldn't use our own black shoe polishes either, we had to use what was issued to us, period, no exceptions.
But they never said we couldn't use a drop or two of kerosene with it, hi hi.

I have some Bar Keepers Friend. I know you told me it's missing some key ingredients now, but it is the simplest solution to a difficult problem. The electric stove I cook on is my nemesis. Back on the gas stove any crud on the bottom of the pots and pans could be scrubbed off with something like a Brillo pad. That is not possible with electric. It builds up some kind of carbon compound on the bottom of the pots and fuses it to the metal. Some of it could be scraped off, but a lot of it seems to be fused into the aluminum or steel. Abrasives are useless so that the only way to get the gunk off is to dissolve it. That's where Bar Keepers Friend shines. It does not clean things perfectly but it does remove more of the carbon deposits than anything else does. Well, I've not tried a wire brush yet, but that might damage the finish.

I'll probably keep the Wenol in the kitchen cabinet next to the vinegar, ammonia, oxalic acid, and stove top cleaner (the gods only know what's in that stuff). I don't use oven cleaner but my wife does for certain things. I believe it has diluted hydrochloric acid as its main ingredient, and I don't like messing with things that corrosive, the baking soda I stock notwithstanding.

Sounds like you have all the necessary chemicals you need to keep things sparkling clean.

Bar Keepers Friend makes a full-strength version, comes in a silver can with the word Cookware on it.
But I don't think it works as well as a product called Carbon-OFF, which is way more expensive.

I cheat sometimes, using an old skillet that is not seasoned.
I pour some vinegar in the skillet and let it boil for a few minutes, then turn it down.
Add some baking soda and stir, then I will set a saucepan with carbon on the bottom in that and let it sit till cool.
Then hit it with the Bar Keepers Friend and some elbow grease.

I have a silver baby size drinking cup with my name engraved in the front.
I cleaned that sucker until it was spotless and looked like new again.
Put it on a shelf where other things got set in front of it for like 15 years now.
Touched that sucker and got black soot all over my hands. So set it right back where it was and hid it again, hi hi.

I do indeed have a chemistry lab under my kitchen counter, and that bothers me quite a bit. It should not be necessary. A need to clean the pots and pans is the byproduct of cooking. That part I can understand and am prepared for chemical warfare in that field. The stove itself should be a convenience and not a challenge to keep clean. Most of that chem lab I have is for the stove and not the pots. Even my complete arsenal isn't enough at times. There are times, such as when entertaining for Thanksgiving, when I manage to get the surface mirror clean. But as soon as I do as much as boil a pot of water on it, the marks begin to show. The burners where actual cooking takes place builds up the same kind of crud as do the metal pots. But, amazing as it might seem, the hardened ceramic seems to absorb more of the carbon than does the metal cookware. They physics of it says no, but the stove is way harder to clean than are the pots and pans. I blame it on the electric burners.

I've seen silver cleaning solution that does its magic simply by dunking the object into a container full of fluid. No rubbing or scrubbing necessary. That's MY kind of cleaning. LOL Now all I need to do is stock up on silverware.

I've read about the boiling vinegar and baking soda technique. When that fails there is a last resort. Fill a pan with ammonia, then place the greasy object to be cleaned in the pan. Bake it all on low heat for a few hours and let it sit over night. The grease peals off easily after that. This also works for cleaning the oven itself, but mine never got that dirty ... yet.

I LOVE the Dip and Clean, when it works, hi hi.

Be very careful if you use ammonia. It reacts with many cleaners and puts out toxic fumes.
That being said, I'm a BIG USER of ammonia myself, hi hi!

I hope you had a great Turkey Day! WITH PI, hi hi.

Yes, I know the potential dangers of using ammonia. In fact I often wondered why they allow it to be sold to the general public. It's great stuff, but like anything else that works well it needs to be used cautiously.

Which brings me to the Wenol I purchased. This morning I thought I would try it out on one of the stainless steel pans that I've been working on for months. It's everything you told me and more. That stuff really worked well on the pan in spite of it needing some elbow grease for an assist. I wasn't too interested in getting the whole pot down to the bare metal at this time, but I can tell Wenol will do it. It's truly amazing stuff and I can't thank you enough for bringing it to my attention.

I was in a bit of a hurry because the house was full of relatives left over from yesterday's Thanksgiving. The two granddaughters who live in NYC came over as did their mom who recently moved to Grand Rapids, Michigan. The one gal from NYC brought Lox and Bagels; that is traditional Thanksgiving food, right? She has a genuine New York Jewish deli within walking distance from her apartment. It all got past TSA at the airport and she used some frozen bags of fruit, being vegan, to keep things cool during the flight. We all feasted on this for Thanksgiving breakfast. Oh, and the turkey we had for dinner was good too. LOL
