Subject: [TekScopes] Re: CONTACT CLEANER - note Cramolin Red is 'Tweek' (!)


That is: the active ingredient is same - made by Wright (audio type
and inventor? discoverer? of the phenom) in Canada. Tweek was first
and invented that T. They fought, and Caig was enlisted to catch
up in 'marketing'. Anyway it is the surfactant which produces the
long-lasting 'miracle intermittent' cures - whatever the label logo
or the diluent decided on. Sometimes brush applicator beats spray -
matter of choice.

FWIW.

For many years we used a contact cleaner "Cramolin Red" which used

to be distributed by Caig. I went searching for new supplies and
discovered that Cramolin is actually German and that Caig's Deoxit is
actually their knock-off of Cramolin and is probably just as
effective.

We achieved miracles with Cramolin. Temperamental equipment that

was plagued with intermittent faults became totally reliable after it
was disassembled and all connectors and contacts treated with the
Cramolin Red. More recently I have been able to resurrect some Tek
plugins and frames that had been stored in a hostile environment by
first cleaning switch and other contacts with isopropyl alcohol to
rinse away water and alcohol contaminants and then applying Cramolin
to attack the oxides and leave a protective, conductive lubricant.
This process failed on equipment that had clearly been underwater so
dont expect the impossible.

I notice that Cramolin is still in business. I just ordered Caig's

sample kit and shall compare it to my Cramolin Red dregs and report
the result.

On the subject of cleaning used Tek equipment my biggest problem

has
been with labels. I find the following method works:

1. Heat the label and attempt to peel it off.
2. Use "Goo Gone" lemon oil solvent to attempt to

dislodge it. This is a mild solvent that seems to be kind to
plastics.

3. Add some WD40 if it is stubborn. This is a stronger

solvent so take more care with it.

4. Aged label adhesive sometimes still resists and then

I carefully use some nail polish remover if there is metal or
anodizing underneath, using a moistened pad like an art restorer.

5. On a painted or plastic surface where acetone cannot

be used remnants can be removed with a scraper using a similar
technique one might use to scrape a bearing or a lathe bed (i.e. no
gouging).

6. Finally clean with a pure water and "Red Juice"

solution. Red Juice is an industrial cleaner that we use and source
from "The Clean Team" in San Francisco. It is a detergent without
other additives and leaves no residue, no pine smell, just clean.
They also make "Blue Juice" which is great for cleaning glass.
