You can use a variety of household and specialized products to clean car upholstery, but the best choice depends entirely on your seat material. For fabric upholstery, a simple mix of dish soap and warm water is highly effective. For synthetic leather (vinyl or leatherette), an isopropyl alcohol and water solution works well, while genuine leather requires a pH-balanced, dedicated leather cleaner to avoid damage. Always test any cleaner on a hidden area first.
The first step is to identify your upholstery type, usually found in your owner's manual. Using the wrong product can cause discoloration, staining, or cracking. For general grime, a vacuum followed by a gentle scrub with a soft-bristled brush is key. For stubborn stains like coffee or ink, you might need a specialized upholstery cleaner or a portable extractor for a deep clean.
| Cleaning Solution | Primary Use | Dilution Ratio (Solution:Water) | Key Consideration | Best For Material |
|---|---|---|---|---|
| Dish Soap & Warm Water | General Grime, Light Stains | 1:10 | Rinse thoroughly to avoid residue | Fabric |
| White Vinegar Solution | Odor Removal, Disinfection | 1:1 | Strong smell dissipates as it dries | Fabric, Vinyl |
| Isopropyl Alcohol | Grease, Ink, Sticky Residue | 1:1 | Test on colorfastness; dries quickly | Vinyl, Leatherette |
| Baking Soda Paste | Set-in Stains, Odors | Paste Form | Let sit, then vacuum/wipe away | Fabric |
| Commercial Leather Cleaner | Conditioning & Cleaning | As Directed | Preserves natural oils; prevents cracking | Genuine Leather |
| Ammonia-based Cleaner | Tough Stains on Vinyl | 1:10 | Use in well-ventilated area only | Vinyl |
| Oxygenated Bleach | Whitening Fabric | As Directed | Safe for colors; avoid chlorine bleach | Colored Fabric |
After cleaning, proper drying is crucial. Park in the sun with windows slightly down or use a fan to circulate air. This prevents mold and mildew growth. For leather, a follow-up application of a leather conditioner will restore suppleness and protect against UV damage.

My go-to is a squirt of Dawn dish soap in a spray bottle of warm water. It cuts through the grime on my kids' fabric seats like nothing else. I scrub it with a soft brush, wipe it down with a damp microfiber cloth, and let it air out. For the leather parts, I just use a wipe from the auto store. Simple and it gets the job done without a fuss.

I'm very particular about my car's interior. For my leather seats, I only use a pH-balanced leather cleaner and a separate conditioner. It's an investment. For the alcantara and fabric, I use a dedicated automotive upholstery cleaner; it's formulated to not leave a sticky residue that attracts more dirt. I avoid household all-purpose cleaners at all costs—they can break down the materials over time. It’s about preserving the car's value and feel.

If you're dealing with a bad smell or a mystery stain, baking soda is your best friend. Sprinkle it generously over the fabric seats, let it sit for a few hours—or even overnight—to absorb odors, then vacuum it all up. For a set-in stain, make a paste with a little water, apply it directly, let it dry, and then vacuum. It’s cheap, non-toxic, and surprisingly effective before you try anything harsher.
