Help please! Gear indicator glasses are scratched.
Hi Guys!
I have Shimano Alivio M410 brake and shift levers on my bike. I tried wet sanding with 800, 1200, 1500 and 2000 grit sandpapers in order. After sanding, I applied fine cut rubbing compound by shoes sponge. Scratches are removed but indicator glasses look matte. How can I get rid off matte look of them? Please help me.

Heaven forbid the Maguires Acrylic & Plastic polish cost more than the acrylic lens itself.
Do a search for the parts breakdown .pdf of your particular shifter. Search for the shifter by the model number embossed on the shifter, itself. When you find it, plug the lens component number into your favorite sort engine. SJS cycles or Modern bike probably has it for under $5
You already have them disassembled & washed with soap & water, correct?

Good luck. But, do you really look at gear indicators? I suspect that you don't need them.

Polishing plastic is difficult, but not impossible. Maguire's (at the auto store) makes a plastic polishing compound. Works pretty well, once you've gotten the scratches out. Typically, you would use a slightly-wet foam sponge to apply it. Tape off the areas around the windows, and apply it with the shifter assembled; it'll go faster not trying to keep a hand on a tiny piece of plastic.

+1 on toothpaste, as long as it's not whitening. Seriously. Toothpaste is a mild abrasive, and a lot cheaper than those 'kits' that restore your headlights.
It's worth a try before you spend $$$ on anything else.
