Car Washing MET Value: Official Values, Formula & Calorie Tables
Car washing has a MET value of 3.0–4.5 depending on task type. Learn the official values from the Compendium of Physical Activities, how to calculate personal calories, and how car washing compares to walking, gardening, and house cleaning.
Car washing has a MET value of 3.5 for a standard full wash and scrub, and 4.5 for a vigorous full detail session, according to the Ainsworth Compendium of Physical Activities. A quick rinse and wipe sits at MET 3.0. For a 70 kg person, these values translate to 3.5–5.25 calories per minute depending on how thoroughly you clean your car.

What Is a MET Value?
MET stands for Metabolic Equivalent of Task. It is a standardised measure of how much energy an activity requires relative to sitting at rest.
- MET 1.0 = sitting quietly (your resting metabolic rate)
- MET 2.0 = very light activity (standing, slow walking)
- MET 3.0–6.0 = moderate-intensity activity
- MET 6.0+ = vigorous-intensity activity
A MET value of 3.5 means that washing your car burns 3.5 times more energy than sitting still. This places it firmly in the moderate-intensity physical activity zone — alongside brisk walking, casual cycling, and light gardening.
Official Car Washing MET Values
The MET values for car washing are sourced from:
Ainsworth BE, Haskell WL, Herrmann SD, et al. 2011 Compendium of Physical Activities: a second update of codes and MET values. Med Sci Sports Exerc. 2011;43(8):1575-1581.
The Compendium categorises vehicle maintenance and washing activities with the following MET assignments:
| Wash Type | MET Value | Intensity | Description |
|---|---|---|---|
| Quick Rinse & Wipe | 3.0 | Light | Hosing down, light surface wipe |
| Full Wash & Scrub | 3.5 | Light-Moderate | Soapy scrub, rinse, dry |
| Full Detail | 4.5 | Moderate | Vigorous scrubbing, waxing, interior cleaning |
The full detail value of 4.5 reflects the sustained upper-body exertion involved in waxing and buffing, interior vacuuming, and the repeated bending and stretching needed to clean wheel arches, sills, and the undercarriage area.
Car Washing MET vs Other Everyday Activities
Car washing sits in the same metabolic range as other common household and leisure activities. Here is the full comparison:
| Activity | MET Value | Intensity Level |
|---|---|---|
| Sitting quietly | 1.0 | Sedentary |
| Standing | 1.8 | Very light |
| Car Washing — Quick Rinse | 3.0 | Light |
| Walking (moderate, 5 km/h) | 3.5 | Moderate |
| Car Washing — Full Wash | 3.5 | Light-Moderate |
| House Cleaning (general) | 3.5 | Light-Moderate |
| Gardening (general) | 3.5 | Light-Moderate |
| Walking (brisk, 6 km/h) | 4.3 | Moderate |
| Car Washing — Full Detail | 4.5 | Moderate |
| Lawn Mowing (push mower) | 5.5 | Moderate-Vigorous |
| Snow Shoveling (light) | 5.0 | Moderate |
| Dog Walking (brisk) | 3.5 | Moderate |
| Cycling (leisure, 16 km/h) | 6.0 | Moderate-Vigorous |
| Jogging (8 km/h) | 8.5 | Vigorous |
Car washing (3.0–4.5) is comparable to walking and general housework, placing it well above sedentary behaviour while falling below vigorous cardio. Full detailing at MET 4.5 is slightly more demanding per minute than a brisk walk (MET 4.3).
How to Calculate Car Washing Calories Using MET
The standard MET calorie formula is:
Calories = MET × Weight (kg) × Time (hours)
Example 1: 70 kg person, 30 minutes, Full Wash & Scrub
3.5 × 70 × (30 ÷ 60) = 3.5 × 70 × 0.5 = 122.5 ≈ 123 kcal
Example 2: 80 kg person, 60 minutes, Full Detail
4.5 × 80 × (60 ÷ 60) = 4.5 × 80 × 1.0 = 360 kcal
Example 3: 90 kg person, 20 minutes, Quick Rinse
3.0 × 90 × (20 ÷ 60) = 3.0 × 90 × 0.333 = 90 kcal

What Affects the Effective MET Value During Car Washing?
The Compendium's MET values represent population averages for typical individuals performing the activity at a standard effort level. Your personal effective MET will vary based on:
Scrubbing intensity: Applying consistent circular pressure to remove dirt, bugs, and road grime requires significantly more muscle engagement than a light rinse. Vigorous scrubbers will burn at the high end of the MET range; casual washers will land lower.
Waxing and buffing: Hand waxing and buffing large surface areas with sustained circular arm motion is one of the most physically demanding parts of car care. This phase is primarily responsible for pushing the full detail MET value to 4.5.
Interior work: Vacuuming and wiping the interior requires frequent position changes — crouching, bending, reaching across seats — that increase total metabolic demand.
Vehicle size: Cleaning a truck or SUV requires more walking, more reaching overhead, and more bending to access lower panels than a compact car. The effective session MET may be marginally higher due to the postural demands of working on a larger vehicle.
Fitness level: A less fit individual working near their aerobic capacity during a vigorous wash will have a higher effective calorie burn per minute than a fit person performing the same task with lower cardiovascular strain.
Why the Full Detail MET (4.5) Is Higher Than House Cleaning (3.5)
Both car washing and house cleaning are categorised as household maintenance activities, but full car detailing carries a higher MET for specific reasons:
- Sustained upper body work: Waxing and buffing requires continuous upper body exertion that general house cleaning rarely sustains for the same duration
- Postural demands: Crouching and bending to clean wheel arches, door sills, and lower panels requires significant core engagement
- Resistance element: Applying wax and buffing requires pressing against a surface — a mild resistance training component absent in most house cleaning tasks
- Continuous movement: Unlike house cleaning, which often involves pauses for repositioning, detail work tends to be continuous physical effort throughout
Car Washing MET Compared to Other Vehicle Activities
| Activity | MET | Notes |
|---|---|---|
| Driving a car | 2.0 | Seated, minimal exertion |
| Pumping petrol | 2.5 | Brief standing, minimal effort |
| Car Washing — Quick Rinse | 3.0 | Light activity |
| Car Washing — Full Wash | 3.5 | Moderate activity |
| Car Washing — Full Detail | 4.5 | Moderate-vigorous |
| Changing a tyre | 4.0 | Short, high-effort task |
| Mechanical repairs (general) | 3.0 | Variable effort, often light |
Frequently Asked Questions
What is the MET value for washing a car?
Car washing MET values are 3.0 for a quick rinse and wipe, 3.5 for a full wash and scrub, and 4.5 for a full detail session including waxing and interior cleaning, sourced from the Ainsworth Compendium of Physical Activities.
Is car washing moderate-intensity exercise?
Yes. All three car washing activities (MET 3.0–4.5) meet the definition of light-to-moderate physical activity. The MET 3.5 and 4.5 values for full washing and detailing fall within the moderate-intensity exercise range (MET 3.0–6.0) defined by health organisations.
How does the car washing MET compare to walking?
A full wash and scrub (MET 3.5) is equivalent to moderate-pace walking (MET 3.5). A full detail (MET 4.5) exceeds a brisk walk (MET 4.3). A quick rinse (MET 3.0) is slightly below moderate walking.
