Protecting and Preparing Your Dirty Engine
Remove any debris caught in the engine bay
The engine bay is vulnerable to debris, damaging the engine and its components. Therefore, it is essential to remove any debris from the engine bay.
A splash shield or under-engine cover can help protect the engine from debris on the road. It is made of plastic or metal and attaches to the bottom of the engine.
If you don’t have a splash shield, you can clean the engine bay using a pressure washer and biodegradable engine degreaser. Spray the engine cleaner across the entire engine bay, including the underside of the open hood, and let it sit for three to five minutes. Use a stiff brush to remove heavy deposits, then hose down to remove all the dirt and debris. Remember not to let any degreaser get on your belts.
Protect the electrical system of the car
Water can damage the electrical system of your car. Therefore, it is important to protect it while cleaning the engine.
You can use plastic bags or plastic wrap to cover the sensitive parts of the electrical system, such as the battery, alternator, distributor cap, and other exposed wiring or electronics. It will prevent them from getting wet and reduce the risk of electrical damage.
Disconnect the battery
Before cleaning your engine, it is important to disconnect the battery. It will reduce the risk of electrical shock and damage to the car’s electrical system. Use a wrench to remove the battery cables from the battery terminals. Remember to reconnect the battery after cleaning the engine.
Cover exposed wiring or electronics
While cleaning the engine, it is important to cover any exposed wiring or electronics to protect them from water and other cleaning products. Use plastic bags or wrap to cover the sensitive parts of the electrical system, such as the battery, alternator, distributor cap, and other exposed wiring or electronics. It will prevent them from getting wet and reduce the risk of electrical damage.
Let the engine run for five minutes
After cleaning the engine:
- Let it run for at least five minutes. It will help to evaporate any remaining moisture and dry out the engine.
- Remember not to rev the engine while it is running, as this can cause damage to the engine components.
- After the engine has run for five minutes, turn it off and allow it to cool down for at least 15 minutes before closing the hood.
Degreasing the Engine
Apply engine degreaser
First and foremost, select a suitable engine degreaser. Once you have selected the degreaser, follow the manufacturer’s instructions to apply it to the engine. Make sure to avoid getting any degreaser on painted components to prevent damage.
Allow the degreaser to soak in for three to five minutes
Depending on the level of dirt on your engine, let the degreaser sit on the engine for at least three to five minutes to allow it to work its magic. It will help break up the grime, oil, and grease on the engine’s surface, making removing it easier. However, ensure not to let the degreaser dry up, as it could leave residue and make cleaning more challenging.
Use a stiff-bristled brush to scrub stuck-on grime
After the degreaser has soaked for the recommended time, use a stiff-bristled brush to scrub off any stuck-on grime. Be gentle with the brush, as using too much force could cause damage to the engine’s surface. You can also use cloth to clean the hard-to-reach areas.
Rinse the engine with a regular hose
Once you have scrubbed the engine’s surface, use a regular hose to rinse off the degreaser and grime. Rinse thoroughly and avoid high water pressure, as it could damage the engine’s electrical components.
Wash the car
After rinsing the engine, wash the rest of the car to avoid any potential damage from the leftover degreaser. You can use car soap and water or take your car to a professional car wash.
Cleaning Specific Engine Components
Use a wire brush on battery terminals
To clean battery terminals, it is essential to disconnect the battery cables and allow the engine to cool down for at least 15 minutes to avoid burns and damage to the engine. Once the engine has cooled down, remove the battery terminals and use a soft wire brush to remove any rust or corrosion from the terminals. Using a wire brush is an effective way to clean the terminals without damaging the components. Use soft strokes and avoid brushing too hard to prevent scratches and mess-ups.
Apply baking soda and water to battery acid
Baking soda is an effective cleaning agent for removing battery acid from engine components. To apply baking soda and water to battery acid:
- Mix 3 tablespoons of baking soda with 1 tablespoon of water to paste.
- Use a soft-bristled brush to apply the paste to the affected areas and let it sit for 10-15 minutes.
- After the paste has sat for a few minutes, use a damp cloth to wipe away the paste and rinse with water.
Baking soda is an environmentally friendly and gentle way to clean engine components without causing damage to the engine or environment.
Use a stiff bristled brush and a sponge on plastic parts
Plastic parts on an engine can accumulate dirt and grime over time, making it essential to clean them periodically. To clean plastic parts:
- Use a stiff-bristled brush and a sponge to remove dirt and grime.
- Start by removing loose debris with a soft-bristled brush, then use a sponge with soap and water to scrub the surface.
- Use a stiff-bristled brush for tough stains but avoid using abrasive materials to prevent damage to the plastic parts.
Use brake cleaner to spot clean grime deposits
Brake cleaner is an effective solvent for removing grime deposits from engine components. To spot clean grime deposits:
- Spray brake cleaner directly onto the affected area and let it sit for a few minutes.
- Use a stiff-bristled brush to scrub the surface and remove dirt or grime.
- Wear gloves and protective gear while handling brake cleaner as it is a powerful solvent and can cause skin irritation.
FAQs
Is it a good idea to wash your car engine?
