Solution

1. Preparation

Gather tools: vacuum cleaner, towels, gloves, and a mild cleaning solution.
Ensure the vehicle is parked in a well-ventilated area.

2. Remove and Inspect Cabin Air Filter

Open the glove compartment and remove any contents.
Locate and remove the cabin air filter cover.
Take out the cabin air filter and inspect it for mold or debris.
If dirty, replace the cabin air filter with a new one.

3. Clean and Disinfect the HVAC System

Use a disinfectant spray designed for automotive use and apply it into the air intake (located near the windshield).
Run the HVAC system on high for 10-15 minutes to circulate the cleaner through the ducts.
Turn off the system and let it sit for 30 minutes to allow the disinfectant to work.

4. Dry and Clean the Interior

Remove any wet or damp mats and allow them to dry outside.
Use a vacuum cleaner to remove debris and moisture from the carpets and upholstery.
Wipe down surfaces with a damp cloth and mild cleaning solution.

5. Check and Clear Drainage Tubes

Inspect the drainage tubes for blockages, especially if equipped with a sunroof.
Clear any obstructions using a flexible cleaning tool or compressed air.

6. Seal and Prevent Future Issues

Inspect and replace any damaged door or window seals to prevent water intrusion.
If necessary, apply sealant around the windshield to ensure a tight seal.
