3. Cleaning the Engine Bay
The next step is cleaning the engine bay, the most important and significant one. Our certified mechanics in South Australia have outlined the simple yet crucial steps for cleaning the engine bayy efffectively.
3.1. Dry Cleaning First
As a first step in cleaning an engine bay, we suggest using a soft brush or compressed air to remove dust, leaves and loose debris. Doing so would remove all the dirt that has been stuck to the engine bay for so long. The dust is more piled up around corners and crevices near the hood hinges and windshield area, so focusing on these parts is a must.
3.2. Apply Degreaser Generously
After dry cleaning the engine bay, comes cleaning it with water-based degreaser. As the best auto mechanic near me, we recommend spraying it all over the greasy areas and letting it sit for 5-10 minutes while not letting it dry out. The important thing to remember is to avoid using harsh chemicals. Our mechanics in South Australia emphasise using eco-safe products that are not harmful to rubber or aluminium parts. Because protecting these parts is as important as cleaning the engine bay.
3.3. Scrub Smartly
To further clean the engine bay, we suggest scrubbing smartly. Grab a soft-bristled brush or a toothbrush and start scrubbing tough areas to remove the dirt that is not easily removable. Try using it on places like oil caps, valve covers, and belts. Because these are the places where most of the dirt is attracted.
3.4. Time to Rinse
Now it is time to rinse it gently. The best thing is to use a garden hose on a low-pressure setting. We never endorse pressure washers while cleaning the engine bay. They are a big NO. Because flooding the engine is never good for it.
3.5. Dry and Shine
Drying is probably the last yet still an important step of the whole process. We prefer drying it with microfiber towels. But if you have got compressed air, it’s even better. Precisely blast out the moisture from tight spots to keep your engine running smoothly after this proper cleaning.
We recommend finishing the cleaning process with a light engine dressing. It benefits you on two ends, adding a protective layer on one hand and giving that showroom shine on the other.
4. Post-Cleaning Checklist
Completing the cleaning process is not a dead end. You still have to do a few more things that seem more or less like DIY vehicle inspections. Such as:
- We advise first removing the plastic covers that you put on it before starting the cleaning.
- Reconnect the battery that was disconnected at the start of the cleaning.
- Start the engine and let it idle for 5 minutes. The reason why we emphasise it is that it would also give you an idea whether the engine is working fine or now you have to google ‘best car mechanic near me’.
- Check for warning lights or weird smells so that you know you have not made it worse while cleaning it.
- Just celebrate your clean engine bay in case everything is fine.

When Should You Clean Your Engine Bay
Well, it largely depends on your driving habits and what condition you are driving in. If you are driving in the city only, we advise cleaning your engine bay at least every 6 months. On the other hand, cleaning it every 3 to 4 months is a standard frequency if you are driving in rural or off-road areas. A local mechanic near me, like us, would recommend cleaning your engine bay every 2 to 3 months in case you’re often doing long road trips.
2 to 3 months frequency of cleaning your engine bay is also ideal for a vehicle if it is used for towing. According to our experienced mechanic, routine cleaning is often bundled into vehicle inspections, so consider syncing both to stay consistent. It would save you from expensive repairs in the long run.
