How Do I Remove Oil Stains and East Tennessee Clay From My Concrete Driveway?

Your concrete driveway has two enemies that love to team up: oil drips from your car and that reddish East Tennessee clay that seems to stain everything it touches. So how do you get both off without wrecking the finish? Good news — you can handle a lot of it yourself with simple supplies and a little patience. Here is how.

First, Know What Kind of Concrete You Have

Concrete is porous, like a sponge. If your driveway is unsealed, oil and clay soak straight into those tiny holes. If it is sealed, there is a coating on top that keeps spills out — but harsh scrubbing or strong chemicals can strip that coating away. Before you start, test your cleaner on a small hidden spot. If the color or texture changes, stop.

How Do I Remove Oil Stains?

1. Blot, don't wipe. Wiping smears the oil into a bigger stain.
2. Soak it up. Cover the spot with cat litter, cornstarch, or baking soda. Let it sit a few hours, then sweep it up.
3. Wash it. Mix a few drops of grease-cutting dish soap into warm water. Scrub with a stiff nylon brush. Rinse well.
4. Repeat. Older stains often need two or three rounds. Store-bought concrete degreasers work too — just follow the label.

Never let cleaner dry on the driveway. Work in the shade or on a cool day, and keep the area wet until you rinse.

How Do I Remove East Tennessee Red Clay?

Red clay is made of tiny particles and iron, and that iron is what leaves the rusty tint behind. Once clay dries inside the concrete's pores, it is much harder to lift.

• Rinse fast. If you catch clay while it is still wet, a hose usually does the job.
• Soak first. Wet the area, then apply your cleaner. Scrubbing dry clay just grinds it deeper.
• Try oxygen bleach. A sodium percarbonate cleaner (often sold as oxygen bleach) helps with clay and rust color. Mix it the way the label says.
• Scrub and rinse. Use a stiff nylon brush, then rinse. Expect to repeat this a few times.

What Should You Never Do?

• Don't use muriatic acid. It can eat into concrete and destroy sealant.
• Don't use a wire brush on sealed or colored concrete.
• Don't hold a pressure washer close. Use a wide fan tip, keep it moving, and stay at a moderate setting. Too much pressure pits concrete and strips sealer.
• Don't mix cleaners, and don't let any product dry on the surface.

The Simple Rule

Wet, gentle, repeat. Water first, a mild cleaner, a soft-to-medium brush, several passes, and a good rinse. Some old stains — especially oil and clay that sat for months — may never come out completely, and that is normal.
