[TenTec] Cramolin, etc.

Sun Aug 26 12:43:55 EDT 2012

Good info Mike.  Thanks.  Nice to know the new formula is "current 
technology" and can be used on most all substances without harm.  I presume 
the "5" in the designators is the 5% solution which is most adequate.

As stated earlier, my two bottles are 20+ years old and are the "100 proof" 
formulations.  I dilute with Freon TF for quick applications.

Cramolin was manufactured by Caig Laboratories. Ten-Tec used two iterations,
the Red can was the contact cleaner and the Blue can was the
lubricant/preservative. They still make similar stuff.

Current Equivalents:
Old Red Can = DeoxIT® DN5 Spray
Old Blue Can = DeoxIT® SHIELD SN5 Spray

It is IMPORTANT to note that each formulation has the letter "N" in its part
number.  That denotes the Non drip - Quick Dry Sprays which are SAFE ON
PLASTICS.

Here is a product info sheet:  http://bit.ly/PfCV9u  I suggest you avoid
their "Standard Sprays," which can attack plastics.

You can order from their store at http://store.caig.com/ but there is a $25
minimum. Other places sell it but one can of each will come to a bit over
$25 and used properly will last through the lifetime of your grandchildren.

Sorry to have posted information when it seems to really irritate some old
codgers on the reflector and I said I wouldn't.
