I grabbed a used Trace Elliot combo yesterday used and the tolex is pretty grey and dull. Other than ordering something online is there anything say around the household or wal-mart you can buy to clean up and shine the tolex? Also has a couple rusty screws. I know with things like copper pennys you can use salt and white vinegar and it makes the wear disappear. What about for screws? Any solution for this? One more thing, the rubber ring around the bottom of the speaker is coming off a TINY bit. What sealant can I buy just to secure it in place. I have a home depot nearby. I don't want to drop a ton of cash at British Audio Service to grab screws and was looking for a solution. I don't know if this belongs in amps since it's amp care, feel free to move.
