Types of Best Engine Degreasers

It turns out that best engine degreasers differ not only by the form of application. Some of them are based on water, and others – on petroleum, and there is a class of foaming liquids. Let’s see what are they and which one is the most suitable.

#Water-Based

Degreasers of this type are safe in use and can be applied on various surfaces without damaging them. Even if you overspray it somehow, the formula is not that aggressive. Still, water-based cleaners are effective enough.

#Petroleum-Based

Petroleum-based gunk engine cleaner is cheap and heavy-duty. Its formula doesn’t contain very expensive ingredients. At the same time, there is one huge drawback – you won’t be able to use it on any other surfaces except engine as they are abrasive. Usually, manufacturers put special marking about that on a package.

#Foaming

Foam-based degreaser is usually quick-drying and removes the oppressive dirt from an engine. At the same time, they are more expensive and differ greatly in a formula of ingredients used.

Best Engine Degreasers Buying Guide – What to Look At?

The selection of one or another best degreaser should be made based on several factors.

#1 Type of Cleaner

Cleaners exist in 3 forms: sprays, tribes and foam compounds. It is preferable to buy spray cleaners, as they are easy to use. As for efficiency, they are also among the best. However, in this case, type of packaging is not critical as aerosol engine cleaners could be not found.

#2 Additional Functions

In particular, in addition to good cleaning abilities, detergents should also be safe for rubber and plastic parts that abound on engine components. So, when washing, these elements should not be even partially destroyed.

In addition, it is desirable that car engine degreaser prevents the destruction of electrical wiring in the engine compartment by aggressive elements, and also limits the possibility of a fire. Aggressive elements are fuel, solvents, salts, which can get into the engine compartment from the bottom or top.

#3 Efficiency

External engine cleaner, by definition, should well dissolve the spots of grease, oils (lubricants, engine oil), fuels, wash dried dirt, and so on. The foam spreading over the treated surface gets into hard-to-reach places, which cannot be approached with the help of rags and this is a great advantage of such cleaners. Its further removal can be performed using high-pressure water. As for the effectiveness of composition, then information about it can be read in instructions printed directly on the packaging. It would also be useful to get acquainted with reviews of cleaners.

#4 Budget and Volume

Here you need to think like when choosing any product. Volume should be chosen taking into account the number of planned surface treatments of engine parts. For one-time processing, a small bottle is enough. If you plan to use this tool on a regular basis – it is better to take a bigger balloon. So you will save money.

#5 Safety

Best engine cleaner should be safe not only for rubber and plastic but also other parts of the car, as well as for human health, in particular, for skin, as well as for respiratory system. In addition, it is desirable that it was safe from an environmental point of view.

#6 Ease of Use

The easiest way is to use aerosol cleaners. When using sprays or tribes, there is no need to contact those with your hands, since application takes place away from contamination. As for foam cleaners, it is often necessary to wash hands after using them.
