This is a re-post from a couple of weeks ago and is a very good tip to keep the surround of your speaker drivers in pristine condition and for a lifetime. I'm re-posting this in the event that some of you may have missed my original post and because I see that several people are rebuilding speakers, etc....
My original post on May 12th:
It is now my turn to tell you fine folks about something that I learned from a good buddy,
an older guy, who is a HiFi friend of mine, so, I'm "paying it forward". My friend also owned his own HiFi store, specializing in quality HiFi gear. Unfortunately, the Big Chain stores with all their lower end gear, finally put him about a business
.
He told me about this tip and I now do this using pure mink oil, as he defined, which you can find on eBay. Make sure it's pure mink oil. Get a soft cloth, like an old cotton t-shirt, cut 4"x 4" square of it and get it reasonably drenched with the mink oil. This tip applies to both foam type and/or butyl rubber type surrounds. Carefully wipe the surrounds of your drivers with the mink oil, making sure you apply it uniformly around the entire surround of your drivers. This should be task performed once a year. This tip will forever keep the surrounds of your drivers in your speakers in pristine condition and make them last forever, well as long as you're alive and never crack or fall apart on you. Good tip.
