Cleaning NES games with sandpaper?

[Sonicwolf]

Use sandpaper ONLY as a last resort.

I agree. Its just the simplest way of wrecking the contacts. You can clean without grinding.

I don't see how a high grit sandpaper would be any more harmful than the people using minor abrasives like Brasso.

Once you get up in those high grit counts, they're about as rough as a cat's tongue.

Imagine if you damaged the contacts enough to make them jagged or rough. It could damage the contacts on the system too then. baaaaad idea.

High grit so you only take a few thousandths off the contacts/surface.
