Stainless steel looks good for a lot of things, from accent pieces to kitchen tools. Not only does it give architecture and design a modern twist, but it also makes tools and utensils last longer and work better, especially in the food and car industries.
If you clean stainless steel to a mirror shine, it’s hard to find something that looks better. Stainless steel is used for more than just its shiny, high-gloss look. It’s used for everything from refrigerators to car parts. A lot of people like that it doesn’t need much upkeep and are willing to pay more for the nice look.
Corrosion, high heat, and most chemicals don’t hurt stainless steel very much, which makes it a great choice for use in business, hobbies, and homes. Even though stainless steel is very strong, it can still get old. Over time, the pieces may get scratched or look dull.
You don’t have to settle for stainless steel that isn’t shiny, though. This is one of the hardest metals to clean, but you can get your things back to how they looked when they were new. There is only one basic three-step process you need to know to buff and polish stainless steel, no matter how big or small your job is.
How to polish stainless steel with below three steps:
- Clean the steel and get it ready.
- Smooth out the steel
- Clean and polish the steel
Step 1: Get the stainless steel clean and ready.
Cleaning the surface is the first thing that needs to be done to fix something. When learning how to polish stainless steel, it’s best to start with a clean surface. Any dirt or dust that is still on it can make scratches worse.
The Best Way to Clean Stainless Steel
For a gentle clean, use dish soap or another light soap and a clean sponge. Make sure you get rid of any sticky spots, even if it takes a soft-bristled brush. Don’t use steel wool or anything else that could hurt the stainless steel more.
Use clean water to rinse it off and a clean towel to dry it. Keep in mind that smudges don’t matter right now; you’ll deal with them later.
Getting Rough or Damaged Areas Ready
Before cleaning, pieces that have a lot of spots or rough edges may need to be prepared in other ways. If you welded the piece or it has a lot of surface damage like gouges and cracks, some people like to give it a first once-over with something in the 80 to 120 grit range. It makes the surface even so the finish is better.
Before you do the next step, make sure you clean the piece once more. Any dirt or dust that is left behind could mess up the end product.
Step 2: Polish the stainless steel
At this point, the surface should be clean and dry. Time to get to work. You might not enjoy the buffing or grinding step the most, but you have to do it to get that mirror shine back.
Tips on How to Buff Stainless Steel
To buff stainless steel properly, you need to take your time and try different things until you get it right. You might be able to handle thinner or smaller pieces by hand, but if you want an even finish, a power sander is probably your best bet.
Scrub the stainless steel with sandpaper that is between 150 and 240 grit to start. A lot of professionals say that you should move up from 240 grit to 400 grit, then 600 grit, and finally 1200 grit. A 2000-grit sandpaper could be used to go even further, but it’s probably only needed or good for a mirror finish.
To buff stainless steel, set your sander to 4,000 to 6,500 RPM. Make sure to move the sander 90° away from any scratches that you can see. As you switch the sandpaper to a different grit, make a 90° turn from the last move.
It’s time to move on once the stainless steel piece has a smooth, satiny shine. Keep in mind that you want to get rid of any flaws before you start cleaning for the best results.
Why is it so important to buff stainless steel?
Buffing is an important step if you really want your piece to shine and be so clear that you can almost see your own image in it. When it comes to food and cooking items, it can be easy to just use olive oil or something similar to polish them quickly and be done with it. For some reason, that method won’t work and won’t fix any scratches.
Take a look at this piece of dull, scratched stainless steel. You use your hands to put on oil or shine that fills in all the cracks, even the smallest ones. That polish doesn’t last long because dirt and other things get stuck in the cracks. Soon, every scratch will stand out like a sore thumb. Also, the light bounces off the surface in a weird way, making it look dull.
By buffing stainless steel, you can get rid of scratches and other flaws so that dirt and other things don’t get stuck in the tiny cracks. The several-step process slowly gets rid of flaws and brings out the metal’s best qualities again.
And yes, rubbing takes a lot of time, but it’s the only way to fix the surface and get that nice, long-lasting mirror finish you want.
How to Get a Brushed or Matte Finish
You might not need to spend a lot of time perfecting the finish on some pieces.
A smooth finish is like a simple fix. It works for things that don’t need to be shiny or pretty but do need some work to fix dents and pits. A matte finish is the last step before everything looks brand new and shiny. If you buff with a 240-grit pad and then a 300- or 400-grit pad, you can usually get to the matte level.
With 150 to 240 covered abrasive belts or drums or medium to very fine nonwoven abrasives, you can get a brushed finish.
A coat of 220 to 240 grit abrasive or a very fine synthetic abrasive belt, drum, or disc can give a surface a matte or satin finish.
Right now, you need to pay attention to which way you are sanding if you want to make a brushed finish. To get a brushed or satin finish with a single direction of the grain, you should set the grain pattern with a grinding belt or a grit drum.
A lot of people like the brushed finish, especially in kitchens and other rooms that get a lot of light. A brushed finish gives your products all the shine without the reflection, which we don’t like. It might make your piece a little less resistant to rusting, though, so you might need to add a rust-proofing finish.
How to Get a Mirror Finish
It looks nice, and the mirror finish hides flaws caused by other fixes, like welding. It takes the shine off of stainless steel and makes it simple to clean. But getting that extra shiny finish takes work and time.
When you’re done with the steps above, get ready to do a few more things to finish the process. Different tools and abrasive chemicals are used for cutting buffing and color buffing to make the stainless steel even smoother. Keep in mind that the less cut buffing you need to do at this stage, the better you made the piece in the first stages of rubbing.
Buffing and cleaning kit for stainless steel
For cut buffing, a black stainless steel buffing substance with an abrasive mineral is used. The substance gets rid of the very small scratches that you might not even be able to see. To get the best results, we suggest using the blue duct buffing wheel.
Change gears a little to a rougher grit. To clean your airways, get a new yellow wheel and some brown tripoli substance. If you switch to the brown buffing powder, the color will look better and the finish will be better.
Color buffing is the last step. It brings out the shine of the stainless steel to make it look like a mirror. For a nice, shiny finish, use a green rouge compound with a new white airway buff that hasn’t been used on anything else.
Now take a step back and look at your almost-reflective stainless steel sheet.
We made it easier for you by putting all of those items into one complete stainless steel buffing kit set.
How to Buff and What to Do
To get a fine mirror shine on stainless steel, buffing is the most important step. You should take your time and work slowly.
When you put the solution on the buffing wheel at each stage, be careful not to do too much.
When you buff the color, be gentle. Since you’re just finishing the piece, you don’t need to put a lot of pressure on it. To avoid an orange peel look, slow down. If you use too much of the green rouge substance, just do it again but this time with less pressure and more slowly.
Work the lines as close together as you can while keeping them tight. To get a smooth finish, try not to cross too much.
Quickly go over the piece. Make sure you don’t stay there for more than a second or two.
Always have a lot of clean cloths and sanding wheels on hand so that you can quickly switch them out when you change the compound. It is very important to keep things from getting contaminated, especially when using different abrasives.
Before going on to the next step, make sure you always work with the grain and look over the piece again for any scratches or other flaws. Even though you can go back to an earlier step whenever you want, it’s better and faster to check your work as you go.
Step 3: Make the stainless steel shine.
It takes less work to polish stainless steel, but you might need to be a little more careful. It’s also the best part of the job because you can see the end result.
Stainless Steel Polishing by Hand
You may have used power tools to buff the piece before, but now you want to use polish and your hands to make it shine. For small pieces that won’t take long, it might even be the best choice.
Carefully wipe away any extra compound or dust that was left over from cleaning. A store-bought polish and a clean, dry cloth should give it a nice shine. As you would wax a car, start at one end and work your way across the surface in circles.
After you’re done, use a clean, dry towel to wipe off any extra shine.
How to Polish Stainless Steel on a Machine?
A buffing wheel might be the best way to polish your piece if you have a big job or want a smooth finish. For a more even finish and more shine, learning how to polish stainless steel with a machine might be faster and better.
Cut and color buffing are both important parts of the rubbing step. If you did them right, your piece should already look pretty good. It did leave behind something that hides some of the shine, though, so you need to get rid of it.
Get a good stainless steel cleaner and a buffing pad or wheel to polish it. For five to ten minutes, go over your piece to get rid of any leftover chemicals or other things. Do not forget to wipe off any extra shine.
The finished item should look shiny and new, with no more marks or noticeable streaks, no matter which finish you choose.
