How to Clean an Outdoor Car Cover: A Complete Step-by-Step Guide
Share
An outdoor car cover is exposed to much more than your vehicle so over time you should know How to Clean an Outdoor Car Cover. A car Cover will collect dust, road grime, bird droppings, tree sap, pollen, salt, moisture and other outdoor contaminants. If the cover is not cleaned regularly, this buildup can affect its appearance, odour and overall condition.
Learning how to clean an outdoor car cover properly is therefore an important part of car-cover maintenance. The good news is that most covers can be cleaned without complicated equipment. The key is to use gentle cleaning methods that suit the cover's material and avoid damaging waterproof coatings, protective finishes or soft inner linings.
Car Covers and Shelter offers outdoor covers designed for Australian conditions, including weatherproof and specialised protection options. Its outdoor car cover range includes products intended for different vehicle types and levels of outdoor exposure.
Here is a practical step-by-step method for cleaning and maintaining an outdoor car cover.
Why Should You Clean an Outdoor Car Cover?
A car cover acts as a barrier between your vehicle and the outdoor environment, so it naturally becomes dirty. If it is not maintained as per the manufacturer's instructions, your warranty will be void.
Dust and fine grit can settle into the fabric. Bird droppings and tree sap can leave stubborn spots, while rain and humidity can contribute to moisture and unpleasant smells if the cover is stored incorrectly.
Regular cleaning can help:
- Remove accumulated dirt and dust
- Reduce stains and unpleasant odours
- Keep the cover looking cleaner
- Prevent contaminants from transferring to the vehicle
- Make the cover easier to inspect for damage
- Support longer-term cover maintenance
For Australian vehicle owners, cleaning can be particularly useful because outdoor covers may regularly face strong sunlight, rain, dust and coastal conditions. A quality cover can provide an important layer of protection, but it still needs appropriate care.
Before You Clean Your Outdoor Car Cover
Before washing anything, check the manufacturer's care instructions. This is one of the most important steps because outdoor car covers are made from different materials and may have specialised coatings or linings.
Some covers may be designed for hand washing only, while others may have specific recommendations concerning detergents, water temperature and drying.
Avoid assuming that every car cover can go into a washing machine or dryer.
- You should also gather:
- A clean bucket
- Cool or lukewarm water
- Mild detergent suitable for the material
- A soft sponge or microfiber cloth
- A garden hose with gentle water pressure
- A clean, open area for drying
Avoid bleach, strong solvents, abrasive cleaners and stiff-bristled brushes unless the manufacturer specifically recommends them.
Step 1: Choose the Right Time and Location
Clean your cover on a mild day when you have enough space to rinse and dry it properly.
A clean driveway, paved area or suitable outdoor space can work well. Avoid placing the cover directly on a dirty surface while cleaning it because soil and grit can transfer back onto the fabric.
If possible, avoid cleaning during extreme heat. Very hot surfaces and intense direct sunlight can make the cleaning process more difficult and may not be suitable for some materials.
Step 2: Remove Loose Dirt First
Do not immediately start scrubbing a dirty cover.
First remove loose dust, leaves and other debris. Shake the cover gently if it is safe and practical to do so, or use a soft brush to remove loose particles.
This step matters because rubbing dry grit into fabric can create unnecessary abrasion.
Pay particular attention to seams, hems and areas around straps or elastic edges, where dirt can accumulate.
Step 3: Rinse the Cover Gently
Lay the cover out and rinse it using clean water.
A garden hose can be useful, but avoid excessive water pressure. The objective is to loosen dirt rather than force water aggressively through the material.
Work systematically across the cover, paying attention to visibly dirty sections.
If you are cleaning a large SUV, ute or 4WD cover, work in sections so that the entire surface receives attention.
Step 4: Wash With Mild Soap
Add a small amount of mild detergent to a bucket of water according to the detergent's instructions.
Use a soft sponge or microfiber cloth to gently clean the surface.
There is generally no need for aggressive scrubbing. Instead, use gentle circular movements over dirty areas and allow the cleaning solution to loosen the grime.
For bird droppings, tree sap or other stubborn contamination, allow the area to soften with water before gently wiping it.
This is safer than attacking a dry stain with a stiff brush.
If your cover has a soft or non-abrasive inner lining, take extra care with that surface. Some outdoor covers use protective inner materials specifically designed to reduce scratching against the vehicle. For example, the Stormguard range listed by Car Covers and Shelter uses a soft, non-abrasive backing.
Step 5: Rinse Thoroughly
Once you have cleaned the cover, rinse it thoroughly with clean water.
Leftover detergent can attract dirt or leave residue on the material, so do not rush this stage.
Run water across the entire cover until there is no visible soap remaining.
Check folds, seams and edges carefully because cleaning solution can remain trapped in these areas.
Step 6: Let the Cover Dry Completely
Drying is just as important as washing.
Never put a wet or noticeably damp outdoor car cover into storage. Trapped moisture can contribute to unpleasant smells and may encourage mould or mildew.
The safest general approach is to allow the cover to air dry completely.
Depending on the cover's care instructions, you can hang it over a suitable clean structure or spread it over a clean area where air can circulate.
Avoid using a high-heat clothes dryer unless the manufacturer specifically states that machine drying is suitable.
Also avoid ironing the cover or exposing it to unnecessary heat.
Step 7: Inspect the Cover Before Using It Again
Once completely dry, inspect the cover carefully.
Look for:
- Small tears
- Damaged seams
- Loose straps
- Worn elastic
- Holes
- Deteriorated sections
- Contaminants that were not removed during cleaning
A clean cover is also easier to inspect.
If you notice significant damage, consult the manufacturer or supplier to determine whether repair or replacement is appropriate.
How Often Should You Clean an Outdoor Car Cover?
There is no universal cleaning schedule because outdoor exposure varies.
A vehicle parked beneath trees may collect more sap and leaves than one parked in an open driveway. A vehicle near the coast may encounter more salt-laden air, while a dusty environment may require more frequent cleaning.
As a practical approach, inspect your cover regularly and clean it whenever you notice significant dirt buildup, staining or odour.
You should also clean it after particularly dirty conditions, especially if the cover has accumulated bird droppings, mud or other contaminants.
Regular inspection is more useful than following an arbitrary cleaning schedule.
Common Outdoor Car Cover Cleaning Mistakes - How to Clean an Outdoor Car Cover: A Complete Step-by-Step Guide
Knowing what not to do is just as important as knowing how to wash a car cover.
Using harsh chemicals
Bleach, strong solvents and aggressive cleaners may damage fabric, coatings or protective finishes.
Scrubbing too aggressively
A stiff brush can cause unnecessary wear. Use gentle cleaning tools unless the manufacturer recommends otherwise.
Washing without checking instructions
Different covers have different materials and construction. Always follow the manufacturer's instructions where available.
Storing the cover while damp
Moisture trapped during storage can create odours and other problems.
Cleaning only the outside
If the inner surface has collected dust or debris, it should also be checked and cleaned according to the manufacturer's instructions.
Putting a dirty cover on to a dirty vehicle
The cover is designed to protect the vehicle, but heavy dirt or grit on either surface can increase the risk of unwanted abrasion. Keeping both the vehicle and cover reasonably clean is a sensible maintenance practice.
Can a Car Cover Be Machine Washed?
Indoor covers can usually be machine-washed but it is unlikely your outdoor cover can be washed in a machine.
Some covers may tolerate machine washing, but others may be damaged by agitation, heat or unsuitable detergents. The correct answer depends on the particular cover.
Always check the care label or manufacturer's instructions before putting it in a washing machine.
When instructions recommend hand washing, follow that method instead.
Can You Pressure Wash an Outdoor Car Cover?
It is generally better to avoid high-pressure cleaning unless the manufacturer specifically approves it.
Strong water pressure can place unnecessary stress on seams, fabric and coatings. Gentle rinsing is usually a safer approach for routine maintenance.
