Gunk - a great name and a great product. It's a degreaser specifically formulated to get rid of really tough oil and grease build-up on engines. This includes both indoor and outdoor engines and cars, trucks, motorcycles and bicycles. It's also used in the marine environment and on any power equipment that's used outdoors, such as in gardens.
Gunk is the leading name in degreasants and has been for the last 50 years. It's able to tackle really tough grease and grime that other products can't shift.
It's important to use degreasers to tackle grease and oil that have built up around the engine because, if left there, these areas of dirt can cause heat spots which can damage the engine and also reduce its efficiency. Degreasers are also useful when you are looking to diagnose a fault or leak in an engine, as cleaning off any grease enables you to get a better look at what is actually going on.
We stock two sizes of Gunk engine degreasants - 500ml and 1 litre. These are both in the brush-on format, which enables you to apply the Gunk precisely to problem areas. However, you'll need to pour out the amount you want to use into a separate container to avoid contaminating what's in the bottle.
The product works best when the engine is slightly warm, so switch on the engine for a few minutes before you start work and then switch off. You mustn't use Gunk on a hot engine or on any hot surface, and you should cover up any electrical parts before starting. Similarly, if you're going to use it on a painted or lacquered surface, check a small area first.
Lots of people ask where the name came from. It was originally a degreaser called Engine Brite made by an outfit called Gunk Laboratories. The story goes that the person who invented Engine Brite was a biker who was asked by a fellow motorbike enthusiast for some of that "gunk" to grease his bike. And the name stuck.
