Lubrication is vital for keeping your car’s mechanical parts running at their best. Remember, friction isn’t your car’s only enemy. Grease, dirt, and debris can also corrode your mechanical companion. Is there a solution for your car’s cleanliness problems? Let’s explore the details of how to degrease your engine.

Degreasing: What and Why?

Your car goes through a lot every day. Amid all the roars and squeaks, what’s hiding under the hood might surprise you. Dirt and dust can accumulate over time, eroding valuable components of your car. And let’s be honest—nobody likes a messy engine bay. How much grease is too much? Only when you start seeing sticky grease stains and residues in the hardest-to-reach corners of your vehicle. All these factors affect your car’s resale value and eventually lead to frequent repairs. Simply put: just degrease.

Degreasers provide the right “solutions” for your vehicle’s oil-free cleaning needs. Composed of solvent-based cleaning agents, they help remove dirt and grease from your car’s shiny metal surfaces. Beyond the automotive industry, degreasers have found a place in various engineering marvels such as airplanes, nuclear plants, and marine projects, to name a few.

Let’s see how degreasers can help maintain your vehicle’s engine performance at its best.

Benefits

In 2020 alone, the United States spent an astounding $175 billion on vehicle repairs and maintenance—a striking statistic highlighting the importance of car care. But why add degreasing to your expenses if you’re a car enthusiast?

Performance:
In addition to leaving your engine sparkling clean, degreasers help remove road grime buildup, improving engine performance. As a rule of thumb, the more dirt you remove from the engine exterior, the less likely it is to accumulate in your filter. Drive without worries!

Appearance:
Decorate your car with the flashiest rims and decals, and let everyone admire you on the road—but the truth is under the hood. What sets a true car lover apart from an “average enthusiast” is how well the vehicle is cared for from the inside out. A quick 15-minute degreasing session could even increase your car’s resale value.

Diagnostics and Maintenance:
Routine vehicle inspection is like your annual medical checkup. Among the complex components and mechanisms of your car, damage can remain hidden in hard-to-reach areas. Proper degreasing removes old residue buildup and can reveal dangerous leaks that have gone unnoticed for a long time. Degreasing helps diagnose issues early, allowing solutions before problems worsen and affect your finances.

Convenience:
Beyond the engine, degreasers can also clean rims, hubcaps, and upholstery. Instead of using traditional soap and sponge methods, degreasers are formulated with specialized solvents that make cleaning more efficient and convenient. The goal is to encourage regular car maintenance to extend its longevity.

Cost-Effectiveness:
Degreasing reduces the likelihood of unnecessary repairs. The money saved on repairs can be reinvested in other areas of the vehicle. With rising gasoline and diesel prices, spending on maintenance has decreased for many users. Degreasers range from $15 to $30, depending on volume and quality. In terms of ROI and protection, degreasers are worth it.

Tips and Application

There isn’t a single “perfect time” to degrease your engine—it usually depends on how heavily your vehicle is used. It’s recommended to degrease your engine every 6,000–10,000 miles. It’s also a great idea to degrease the engine after an oil change. Here are some tips before you start:

Mind the weather: Choose a sunny day. Warm weather helps the engine dry faster after degreasing.
Let it cool: Wait at least 15 minutes after turning off the engine to avoid burns while the engine is still hot.
Beware of static electricity: Disconnect the negative battery terminal. Avoid a trip to the hospital due to electrocution, as your battery could be exposed to water during cleaning.
Be careful with plastic parts: It’s recommended to remove any plastic components before degreasing, as you can clean them separately.
Protect electronics: Cover or remove any electronic components to avoid unwanted damage during cleaning.
