Buyer Guide- How to Choose the Best Engine Degreaser
Best engine degreasers will not just wipe off your engine’s surface. If anything, it will give it a sparkle especially if contains petroleum as a makeup element. However, there are numerous other factors to consider when shopping for one. For example, it’s always advisable to first assess the fragility of the part of the engine you seek to clean. Why? The building agents of most grease cleaners are pure chemicals and can easily corrode paints, rubber, and other sealing surfaces.
Types of Engine Degreasers
Looking for an effective engine degreaser? Here are the different types you’ll find on the market today.
- Petroleum Based Degreaser
This type of degreaser contains a solvent capable of washing off the grease and dissolving the residues resulting from the chemical reaction of the process. It contains ethanol as its main building block. The flip side though is that it can decolorize surfaces over time.
- Metal Solvent Degreasers
These are excellent cleaners of moving parts of the engine such as the bearings, rotator belts, and crankshaft joints. They work by dissolving dirt.
- Foam Degreasers
Other than cleaning engines, you can apply these on electrical contraptions due to their poor electron conduction nature. They do not require rinsing with water after use.
Factors to Consider When Buying the Best Degreaser
A search for the best car engine degreaser can be overwhelming and time-consuming. However, several pointers can ease your odyssey and solve your problem much quicker.
Take a look:
Engine parts are expensive and thus what you apply on them ought to be innocuous. The chief role of a degreaser is to eliminate grunge and any unwanted substances- it should achieve this without reacting with your engine’s coating or your hands. Luckily for you, the cleaners we reviewed earlier on for you are not only harmless to steel but also on rubber and paints. The only exceptions are the degreasers which we instructed you to dilute first before using them.
Best degreasers will not just wipe off grease but also inhibit its formation in future. Engines coated with iron or its alloys are likely to fall prey to rust and accumulation of dust over time. Degreasing them with multi-purpose cleaners will often be an adequate measure.
Find a top engine degreaser that will sufficiently serve both the engine and other moving parts that require regular cleaning.
Solvent-based cleaners are notorious for releasing irritating scents. If you have respiratory shortcomings, you should instead opt for water-based degreasers.
- Evaporation Factor
Highly concentrated chemicals escape into the air when exposed. It is, therefore, prudent to purchase degreasers that are vapor-proof to increase their durability and effectiveness. However, should you buy products of this nature, ensure you dilute them before use.
How to Clean Your Engine using a Degreaser at Home
Having walked you through the process of choosing the best degreaser, we feel it’s an appropriate time to show you how to clean the engine at home. But first, let’s go through some ground rules:
- Never attempt to degrease a hot engine. This way, you run the risk of damaging its surface by corroding it. Keep it cool or warm if you must.
- Cover electrical parts- They are often highly sensitive to degreasing formulas especially the petroleum-based ones. Ensure you have pressurized running water to rinse your engine once you are done with the cleaning.
- Ensure you have pressurized running water to rinse your engine once you are done with the cleaning.
- Dispose of all materials responsibly.
Having these degreasing tips in mind, we can now proceed the next stage.
For demonstration purposes, we’ll use Gunk engine degreaser which is one of our favorite cleaners by the way.
By the end of the exercise, you should be able to clean the dirty engine with minimal fails. So, roll up those sleeves and let’s get working;
- The Gunk Degreaser in a spray bottle
- A water hose
- Washing brush with firm bristles
- Waterproof plastic bags
- Dirt absorber preferably from a woolen material.
Step 1: Shielding
First, cover all the engine parts that you do not target for your cleaning which helps shield them from coming into contact with contents of the degreaser. Usually, these are electronic components such as the alternator, the fuse box, the distributor, and the air filters. Water-resistant materials such as plastic bags will suffice. Also, cover up the surface where dirt and other drippings will fall. We recommend an absorbent material since it guards against spilling over of the soiled content.
Step 2: Dilution
This step is optional. You can use petroleum-based products, warm water, or natural degreasers for this. The aim is to lessen chemical concentration and prevent discoloration of your engine. Dilute Gunk degreaser only when fragile parts are involved.
Step 3: Saturation
The objective here is to soak the engine surface. Sprinkle Gunk degreaser repeatedly until particles begin falling off by themselves. Use a brush with firm bristles to wipe off regions that are heavily soiled or aren’t well saturated. For a shinier output, ensure your degreaser doesn’t dry off. You can direct a stream of water over the surface while at it.
What Are the Benefits of Cleaning Your Engine?
- Spot Engine Leaks and Dents
Let’s face it, no one wants to one day wake up to the horror of a damaged engine. Leaks are the primary contributors to such situations since they allow coolant liquids to spill leading to overheating problems. A great engine degreaser, however, will help increase your visibility towards these faulty spots.
- Aesthetic Purposes
A clean engine translates into an attractive, high performing beast. Dirt and dust block your auto’s beauty and lowers its value. In fact, many motor purchasers and vendors tend to be overly concerned about the appearance of the engine. Luckily, a good degreaser can help you maintain your engine’s aesthetic value quite effortlessly.
- Make the Engine Durable
The cleaner your engine becomes, the longer the mileage it covers. Grunge increases the possibility of peeling off of the engine’s surface. The more it accumulates, the weaker the surface becomes. Degreasing prolongs its life and saves you big on stresses and unwanted expenses.
Remove the protective gears you had put on earlier. Dump the absorbent material away from the working area. If it’s reusable, soak it in water and apply cleaning detergents. Hold on for about thirty minutes before running your engine.
