Scratched discs - what do to?


I can't be the only person with this problem. My new GamuT CD-1 is wonderful, etc. (see my system), but it is sensitive to scratched discs. Email from the designer indicates that he decided on sound quality at the expense of robust correction (which, I guess isn't 'correction' so much as 'guessing').

Unfortunately, I have a good number of old discs that have been around the block a time or two--lent to friends who leave them out and stack them, caseless; carried around NYC in sub-par cd wallets (mea culpa); dropped, forgotten, lied to...

How can I fix them? I have heard of a number of products--potions, polishers, scrapers...

The following is a purely ad-hoc list of possible solutions. Can anyone comment? I'd love to just buy one that works instead of building a library of products that don't.

Novus #1 Plastic Cleaner
Novus #2 Fine Scratch Remover
Novus Perspex polish
Allsop cleaners ?
Brasso polish ?
Discwasher CD scratch repair kit (cleaner and polisher liquids)
Discwasher CD Cleaning system (turntable thingy)
BlueNote Galaktos CD treatment
Nitty Gritty Pure CD Fluid
Auric Illuminator kit - gell and pen (does this fix scratched discs?)
Mapleshade Mikro-Smooth polish
Mapleshade Optrix (enhancer?)
Finyl cd cleaner
Disc Doctor - Miracle CD Cleaner
Walker Vivid Cleaner kit (marketed as an enhancer, not a scratch remover.)

I'm leaning toward the Mapleshade combo--they seem to have good feedback on their website (not surprisingly), and the products seem fairly priced. Anyone here used it? (Anyone used their Maple platforms?)

Thanks. I will report results back here.

Regards,
Chris

There's already at least one other thread with this topic- start by searching the archives.
Of the various products you list, the only one I have personally used is Mapleshade's Mikro-Smooth polisher. I have found it to be very effective at making scratched CD's playable, and even disks in good shape seem to sound better when they've been polished with this product.
I second the Mapleshade Mikro-Smooth as a general polish/enhancer. Also like Vivid and have been experimenting with Auric Illuminator as well. For those really badly scuffed/scratched CDs, though, I've had as much luck with toothpaste (not gel) as anything else. Just rub it in on the scratch/ding/scuff with your finger and rinse. No, I haven't done a toothpaste brand-by-brand comparison!
