Types of Engine Degreasers

Choosing the best engine degreaser includes taking respect of the type of product that you want. Degreasers aren’t a one-form solution for every engine. There are different formulations that likewise determine how useful or effective a degreaser will be.

Environmentally Friendly Degreaser

This is a kind of engine degreaser that is known to be exceptionally effective and recommendable. Its formulation usually comprises of baking soda, vinegar, lemon juice, cornstarch, castile soap and sometimes citrus oils. The resultant formulation is ideal for use on stainless steel, copper, brass and glass surfaces.

Experts recommend using low volatile organic compounds (VOCs) on automobile engine cleaning in order to prevent breathing problems and air pollution while using these products. Some degreasers in this category arrive with cleaning formulation, thus offering a combined task.

Metal Solvent Degreaser

This degreaser type is effective in removing grease from engines, joints, bearings, and other components in vehicles and machinery. In some other cases, it serves as a dousing solution to viably expel the grease.

Petroleum-Based Degreaser

This formulation effectively removes grease and gets rid of residues from oil, gasoline and lubricants. The solution usually includes ethanol and distillates, and these substances are ideal for vehicles and their components.

Vapor Solvent Degreaser

This uses a different strategy to remove grease from parts. Unlike applying the solvent to the vehicle part, the part is placed on top of the vapor. Once the vapor is in contact with a vehicle part, gradual grease removal takes place without submerging the part. A solvent degreaser often arrives in a dual-tank unit, with each container having a different solution. The fact that you don’t have to soak the automobile parts is this solvent is a major benefit that attracts many users to this vapor solvent degreaser.

Foam Degreaser

This degreaser type is usually applied to car engines and electrical appliances. It has a simple application method – just wipe the formulation off without using water.

Ultrasonic Degreaser

An ultrasonic degreaser has an advanced formulation that uses ultrasonic waves in grease and residual removal from parts. It comes with a tank in which car parts are placed into for grease removal. This degreaser is often operated for a particular amount of time and because of its small tank, it can also be used for jewelry and mechanical tools.

Critical Engine Degreaser Considerations

To get the best engine degreaser, you need to consider several aspects prior to your investment. There are plenty of options on the market and choosing the right engine degreaser can be so confusing. Here are the factors to consider in your decision:

  • Formulation – a formulation that simply removes the grease should not be final. Look for a dual purpose degreaser that also prevents the grease from forming in the future and the current market is not short of such options.
  • Contents – the contents determine the effectiveness of a degreaser. Terpene-based orange peel is, for instance, considered one of the most useful extracts, while esters are known to prevent build-up of fats and greases on the surface of car parts.
  • Safety – the best degreaser should not just be effective on removing grease from the surface but should also not damage the surface. The formulation should be safe on all kinds of materials, including steel, plastic, rubber and paint.

Still on safety, the formulation should be free from toxic compounds as well as not flammable and corrosive, among other hazards.

  • Evaporation control – this is an important factor to consider especially if you intend to buy a solvent-based degreaser. Look for one with a considerable evaporation rate which guarantees extended and tougher cleaning effects.
  • Odor – are you allergic or asthmatic? Then make sure to choose a degreaser with a weaker or safer odor to avoid breathing problems.
  • Residue – some degreasers may leave white residue on the surface of car parts, thus giving you extra cleaning work. Find a degreaser that dries reasonably without leaving a spot on the surface. One that can be simply rinsed with water could also be an excellent option.
  • Versatility – it makes sense to look for a degreaser that not only works on your car engine but also on other general equipment and machinery.
  • Usage period – some degreaser bottles could work for many engines before running out. Liquid solutions could help save some quantities of the degreaser.
