I found this on the Amazon review site regarding DeoxIT. Looks to be a great product group. W2WEG
DeoxIt comes in many different formulations. All are superior, but choose the right one for the best possible results

DeoxIT is manfuctured by "Caig" but is often sold under the name of one their distrubutors "Hosa". Whether the product you buy says "Caig DeoxIT" or "Hosa DeoxIT" - it is the same product. "DeoxIT" is a registered tradename and that is what you are looking for. Hopefully that information eliminates some initial confusion.
As an electrical engineer I've used DeoxIT for over 30 years. In fact - it is the only contact cleaner, lubricant, and contact enhancer I trust. From Boeing, Bose, General Electric, Hewlett Pack, etc, etc this product is the gold standard and widely used in manufacturing and within professional circles.
Prior to the internet and companies like Amazon this product was unknown and unavailable outside a few professional circles.
Having said that any consumer should be aware that every DeoxIT product is superior, virtually guaranteed to do NO harm and even if you don't use the optimum formulation of DeoxIT it will still improve a poor connection and protect a new one.
DeoxIT is sold in 4 broad categories.
D series - first and foremost a heavy duty contact cleaner combined with contact enhancer/protection - this is Caig/Hosa's most universal product
S series (aka Shield S series) - for outdoor envirnments particularily benefical in salt or other harsh environments. If the connections are not new - cleaning with a D series is required (per the Caig website)
G Series (aka Gold series) - designed for gold and base metals. It offers minor cleaning properties. For gold contacts it offers near perfect protection and will slightly enhance electrical connections for gold, etc. However its cleaning properties are minimal and since gold does NOT oxidize and usually offers a near perfect connection to begin with this product has limited uses. I'd recommend it for very low voltage circuit boards with gold connectors that experience problems.
F Series (aka Fader F series) - designed for "faders" aka "volume controls" aka "pots" (potentiometers) or other rotorary controls. This is a cleaner/enhancer for volume controls or other rotary controls used on a vast number of products (radios, musical amps, etc, etc, etc) that use carbon based (extremely common) or conductive plastic controls
In the end, I hope this description helps you pick the best formula for your needs but the bottom line is the entire family of Caig/Hosa contact cleaners/enhancers are all first class and even if you pick a less than perfect formulation it will do no harm and will likely still fix your problem. The most universal product, as previously noted, is the D series cleaner/restorer.
