DEOXIT Contact Cleaner & Rejuvenator - solution kit

ProGold is specifically formulated to improve conductivity and provide long-lasting protection on gold, precious metals and their base metals. It conditions connectors, contacts, and other metal surfaces, thus enhancing the conductivity characteristics to efficiently transmit electrical signals.

Use it on all the connectors in your system - cartridge clips, RCA sockets and plugs, speaker terminals. The older they are the more you need it.

SB-G100: TECH INFO on ProGold  

ProGold outperforms all other contact cleaners, enhancers and lubricants. Due to its unique properties, it deoxidizes and cleans surface contamination, and penetrates plated surfaces and molecularly bonds to the base metals - NO OTHER PRODUCT DOES THIS. ProGold increases the performance and reliability of all electrical equipment. It improves conductivity for greater definition and dynamics, reduces noise and interference, and lowers distortion. Unlike other products, it also stabilizes connections between similar and dissimilar metals. Provides long-lasting protection (1-10 years) on gold, silver, rhodium, copper, nickel and other precious metals.

Physical and chemical changes in the surface condition of electrical or electronic connectors are primary causes of degraded
performance of components and equipment. When contact surfaces are exposed to dust, smoke, gases, soot, and other solids
suspended in the atmosphere, non-metallic films form, inhibiting conductivity. Added resistance and friction between metal surfaces can also cause abrasion, noise, freeze-up, and in some cases, increased power consumption. 

A common problem with plated surfaces, especially gold, is the "whiskering" (dendrite corrosion) of base metals to the surface dueto gold's soft and porous nature. Once exposed, base metals oxidize causing a "blistering" of the surfaces, adding unwanted resistance that impedes electrical performance. The contact surfaces are actually separated by this blister, thereby reducing the effective contact area. Since gold plated surfaces are thinly coated, they are susceptible to scratching and abrasion, further exposing the base metals. 

Conduction through a ProGold coated surface takes place in three ways, First, ProGold can be displaced by electrical arc, shock wave or simple mechanical pressure and will redistribute itself along the surface when the disturbance is removed. Second, a thin insulating film of ProGold can be dispersed by an electrical field. Finally, conduction takes place through very thin films of ProGold by means of a quantum- mechanical phenomenon called "tunneling." To avoid detouring into a discussion in physics, simply stated electrons travel from one side of a thin film of ProGold to the other without passing through (this is the same effect that gave the tunnel diode its name). ProGold fills the gaps in the contact surfaces, increasing the surface area and current flow (conductivity). ProGold penetrates the plated surface and molecularly bonds to the base metals to seal and protect it. Unlike other products, ProGold provides long-lasting protection (1-10+ years) and will not gum-up, evaporate, varnish, char or breakdown.&nb sp;

ProGold coats the entire contact surface, providing superior protection from abrasion (insertion resistance), dendrite corrosion, arcing, RFI, wear, and atmospheric contamination. ProGold will significantly increase the performance and reliability of all electrical components and equipment.
