Other uses for silicone grease

Silicone grease is slippery stuff and doesn't wash off with water. You can use it to waterproof outdoor connections to LNBs, dish motor connections and to make things slide on more easily. How about those tricky radiator hoses on vehicles?

Silicone grease will also tolerate very high temperatures so it is used on heatsinks in computers and other equipment. (Sometimes zinc oxide is added but this is not essential.)


Apply it to plugs and sockets to make them easier to release.

Apply it to the wall bracket bolts and to all dish bolts and U-bolt threads. This will help to ensure that they can be undone in a few years time.

Apply it to dish fixings, aerial fixings and U bolts.

Outdoor aerial connections need to have a liberal coating of silicone grease. Cut the coaxial cable inner copper core as short as practicable. Twist the copper braided shield into a "pigtail". Coat both with grease before inserting into the connectors and tightening the bolts. Now apply lots of grease to all bare metal so that any rainwater or condensation will simply run off.

Fit the plastric cover and secure it in place with self-amalgamating tape and/or cable ties. Some plastic covers crack and flake away in sunlight so covering them with tape makes good sense for long-term reliabiity.

Silicone grease is also perfect for preventing corrosion on battery terminals in all situations from cars, tractors, boats and lorries to model aeroplanes.

You can also use it as polish to make things shine and to protect them from tarnishing. (I use it on my kitchen work surfaces).

This high temperature silicone grease is also ideal for lubricating the threads of spark plugs. It helps to conduct heat away from the spark plug and makes it easier to remove at the next service.

Also try it on squeaky hatchback door seals.

Corrosion of bulb contacts can cause strange electrical problems when brakes or indicators are operated. Remove each bulb and scrape off all corrosion from the metal cap and terminals. Do this for the bulb-holder, too. Then coat all metal parts (including the contacts) with silicone grease. This does not affect the contact but it keeps out moisture.

Older cars can suffer major problems with intermittent electrics. Every week a different problem might occur. The reason is simply that the connections were made without grease. Connectors come in various guises but the most common are the "bullet" type (which are not easy to clean) and the "spade" type (also known as "Faston" or "Lucar" connectors). Corrosion occurs where metals are exposed to moisture and air, and the problem is exacerbated by heat. Vibration will make the problem intermittent. The corrosion builds up and pushes the contacts apart, then vibration may cause the contact metals to break through the corrosion and contact is remade - for a while. It can drive you crazy! The answer is to remove every connector, clean and grease it. Don't overlook fuses, headlight connectors and engine sensors. Silicone grease is ideal because it is very waterproof and unaffected even by engine temperatures.

Leaking battery cells will cause the spring contacts to corrode. You can help prevent this by coating the contacts with silicone grease.

You can use it in any equipment that uses battery cells - from remote controls, model boats, model cars to hearing aids.

I also used it to prevent crackling audio on my iPod. Read more about this here.

Where should silicone grease NOT be used?

Do not use it anywhere near to switch- or relay-contacts that might arc. Silicone grease forms a glass-like layer when subjected to arcing currents. Its use in telephone exchanges and similar is prohibited.
