Cardas Caps Worthwhile?

When I take off two caps and insert a new component it is still nice to know that there is no extra dust and grime build up inside. Since my rack is 2 feet from a window in NYC I have come to appreciate anything that I don't have to dust or polish twice a week.These things are very easily removed, and don't fall off when brushed by. Perhaps those of us who didn't hear any, or much difference already have a reasonably low RFI problem, and these caps may still help those that have more severe problems, as in a few cases here.

Bmpnyc: Yes, I live in the LA area. We keep an open place (no air conditioning) and the air gunk covers everything (even dishes in closed cupboards). I never thought of putting anything on the unused inputs/outputs until I heard of the Caps. I cannot even see the back of any of my components, but feel better knowing that sticky air stuff is not coating the unused connections (it just makes sense, no matter what you use). Clean contacts are a must for good sound. I cannot believe the improvement in sound when I clean the pins on signal tubes (I have had noisy tubes become silent again, just from this).

Thanks Dekay, I hadn't thought of cleaning tubes since I don't have any at the moment, but my friend just moved and his tubes for his VAV amp desperately need cleaning. How do you clean tours? Should I clean them the same way as the tips of an interconnect, or just a little alcohol rub? I have been using the little handy wipe type cleaner that XLO makes, and an air gun. It seems to do a good job. Haven't been to L.A. for a while now, but always have a good time when I do get there. I guess it comes down to price. I think most everyone would prefer the caps to other home grown methods if they were say...$6 a dozen.

Clean Tours? Unintended antonym!

I just use electrician's alcohol and cotton swabs if the pins are in good condition (also clean the globe with the alcohol). If the the pins are not in good shape I lightly use very fine emery cloth (think that's the name of it) and then follow up with the alcohol. Be very carefull if the pins are gold plated. I would like to try out the Kontak, but still have not purchased it. I just had my amp cleaned and spec'd, but will need to get some brushes (or maybe pipe cleaners?) for the tube sockets as I change tubes quite often.
