r/MetalPolishing

I need help figuring out why my polishing methods aren't working.

For context, I'm an absolute beginner, and I've been using this rotary tool with Scottchen buffing compound. I started off with medium fine (white), then progressed to very fine (green), and I've been getting this blue hazy tint on my nickel surfaces. There are also some scratches I've noticed too. The left-hand object has been polished very lightly and briefly for just a few seconds, while the right one is in its original condition. I cleaned my components with 91% isopropyl alcohol on a microfibre towel and even resorted to dish soap and a toothbrush. However, I cannot get rid of this blue haze. Can anyone please explain to me why this is happening? Do I have a bad polishing wheel? Is it the compound?

Thank you to all in advance,

J.

Hello i’m looking for advice on if these headers could be cleaned up with some elbow grease and time or just sent off the be ceramic coated, the rust doesn’t seem too deep beyond surface level besides the spot with the hole but I have a welder friend to help with that. I really don’t want to have to buy new headers if these can be saved, thanks for any advice

Hello from NJ, America!

I’m hoping for some advice on technique to get better results in wet sanding before finish polish on my bench top.

304 SS [two different pieces]
Porter Cable 7424XP orbital buffer, Speed at 4 [of 6, 1 is 2,500; 6 is 6,800]

I start with 500 grit sandpaper, with water on every grit, then go up: 800, 1500, 2000, 2500, and 3000. I spray water on the pieces to rinse them off between each grit.

Photos are after 3000.

What can I do differently to get more scratches out? Slower speed on orbital? Faster? More time on a certain grit? Use something other than water? I can’t seem to get a good finish. Any advice would be appreciated! 🍻

Brand new home. Brand new appliances. Been here 3 weeks and this has already happened when my mom decided to clean the stove. Any advice on how to remove??

Hallo Metallurgie Fans, ich hab heute dieses Relief gekauft. Ich habe es aufgrund des Gewichts und des Ausssehen sowie der Art der Korrosion als Eisen Relief interpretiert. Es ist wahrscheinlich kein Zink und definitiv kein Kupfer.

Könnt ihr mir helfen, einen Weg zu finden, die Korrosion zu entfernen und nachhaltig das gesunde Eisen vor selbiger zu bewahren? Ich möchte dabei die Patina sowie die Details des Reliefs so gut wie möglich erhalten.

Anybody got any tips to get the tuffer pitting outta the stock wheels. I’ve brought them back pretty well, just a few spots that I just don’t know about. Any tips please and thank you!

Restoring my old wedge and I would like to match the finish on the front face of the club. It looks like a really dull brushed satin with little to no gloss. I cant seem to dull the shine enough to get the effect I would like. I am sanding in one direction, gradually going up in sandpaper grit, started at 100 and worked up to 600, was too shiny still so I went back to the 150 and finished it with a green scotch pad. Still comes out too glossy. I am looking for more of a matte look

1. Is this a completely different finish such as sandblasted or a coating of some sort?
2. Should I try a finer grit scotch pad to dull it more?

Any advice or info is greatly appreciated! Thanks!
