Thanks to you too, Corey.  Just saw that after I sent my last missive.

Thanks for sharing your experience, Shai.


I've been warned off of IPA in the past, being told it could prematurely dry out rollers.  Not hard to imagine if used a lot.  It is valuable to hear you've had success at your rate of use, Shai.


By the way, as once advised by a trusted mentor, I have successfully used 90% or higher IPA mixed 50/50 with water, for rare cases of stubborn cleaning.


I didn't say it well earlier, but the thing I grow concerned about is the combination of fluid AND frequency.  I am concerned that the water I chose to use may be drying rollers out faster now that we have been cleaning more often.  I may be overthinking it, but I quote someone in our book conservation department, "For Conservation use, DI is so pure itís aggressive and will strip paper (documents, book pages, etc) of valuable components.  So in conservation treatment, additives are added back in. "  Granted I am using Reverse Osmosis (RO) or Distilled - maybe not as aggressive as Deionized (DI) - and paper and rubber are rather different.


But maybe my having chosen RO or distilled may already be overthinking roller cleaning and inviting issues if it is not much different than DI.  Is tap water typically just fine for folks out there?


The problems we have had, by the way, are namely tape not tracking well, i.e. slipping side to side as it goes past roller/capstan. I wonder about a reduction in roller suppleness and size.  I know that symptom can be related to capstan drive belt too though.  I've been waiting for months for new drive belts to experiment with too.

A final note: CAIG makes a rubber reconditioner for printer rollers.  I've had success with that, getting paper to pass through a printer more reliably.  Anyone tried it on cassette deck rollers that are suspected to be too hard?


-Karl

Hi Karl
I clean whenever itís needed. Reel to reel about twice a week. Cassettes
about 1-2 a month. I use technical grade IPA
