(OP)
Got a batch of small parts made from 6161. They were tumbled. I need to know how I can make these brighter like the ones on the left.

Engineering is the art of modelling materials we do not wholly understand, into shapes we cannot precisely analyse so as to withstand forces we cannot properly assess, in such a way that the public has no reason to suspect the extent of our ignorance.

For a safer method...
You could try boiling 4 tablespoons of white vinegar to 1 quart of water, drop in aluminum parts for 10 minutes, remove and rinse.

Another option to try is to go to a chemical cleaning supply house and get some Al truck cleaner to see if it gt the parts clean to an acceptable level.
They make caustic cleaners for Al that leave a fair finish. The secret to using alkaline materials on Al is there has to be an inhibitor in the solution. The best one is sodium metasilicate.
If the OP wants bright and shinny Al he will have to use mechanical or hand polishing to such a finish.

Line all the parts up on the table, side by side.
Polish them all at once.
flip.
Repeat.
1000 parts will be polished in no time.
