Clean the One Part You Never See

AJ's Mobile Detailing carefully cleans engine bay components without risking sensitive parts in Grand Rapids.

The engine bay in your vehicle collects dirt, grease, and road debris over time, especially if you drive through Grand Rapids winters or spend time on gravel roads. AJ's Mobile Detailing focuses on cleaning visible engine components, hoses, and covers to improve appearance without exposing electrical parts or sensors to unnecessary water or chemicals.

The service uses quality products designed for automotive engines and is performed with attention to what can be safely cleaned and what should be avoided. It's ideal for maintenance-minded owners who want their vehicle to look complete under the hood or anyone preparing to sell and wanting the engine bay to match the exterior. The work can be done as an add-on to a full detail or scheduled as a standalone service.

Mobile service is available across Grand Rapids, or you can bring your vehicle to the shop if that works better for your schedule.

Careful Cleaning That Avoids Electrical Risk


The detailer inspects the engine bay first to identify sensitive areas like the alternator, battery terminals, and exposed wiring in Grand Rapids. Degreasers and brushes are applied to plastic covers, metal brackets, and hoses where grime builds up, then rinsed carefully with controlled water pressure that won't force moisture into places it shouldn't go.

When finished, the engine bay looks noticeably cleaner with visible components free of caked-on dirt and grease. Hoses and covers that were coated in grime now show their original color, and the overall appearance under the hood looks maintained instead of neglected.

This service does not include polishing, coating, or dressing unless requested separately. It also does not address mechanical issues, leaks, or performance concerns. The focus is purely on appearance and removing buildup that accumulates from normal driving.

People usually have safety questions first

Before booking engine bay cleaning, most customers want to know if it's safe, what gets cleaned, and whether it affects how the vehicle runs.

Is it safe to spray water in the engine bay?
Yes, when done carefully. The detailer avoids direct spray on electrical components and uses controlled pressure to rinse only the areas that have been degreased and brushed.
What parts of the engine bay actually get cleaned?
Plastic covers, hoses, metal brackets, the firewall, and visible surfaces are cleaned. Sensitive areas like the alternator, battery, and wiring harnesses are avoided or protected during the process.
Will this improve my vehicle's performance?
No, this is a cosmetic service. It removes dirt and grease to improve appearance but does not affect how the engine runs or address any mechanical issues.
How long does engine bay cleaning take?
Most engine bays take 30 to 45 minutes depending on how dirty they are. Heavily soiled bays with years of buildup may take closer to an hour.
Can you do this at my house in Grand Rapids?
Yes, mobile service is available throughout Grand Rapids. The detailer brings all products and tools needed to clean the engine bay on-site at your location.
