How to Clean Concrete Off a Car

While construction and remodeling projects are going on, accidents and spills can occur very easily. A common accident is a splatter of cement mix landing on items such as a car parked in a work area. If you don't reach the cement right away and wash it off with water, it will harden into concrete; and if you try chipping it off, the paint will come with it. With the proper supplies you can clean concrete off of a car.

Things You'll Need

• Protective eyewear
• Mask
• Rubber gloves
• Muriatic acid
• Water
• Bowl
• Sponge

Instructions

1. Purchase muriatic (HCl) acid from your local hardware or home store.

2. Pour 1 cup of muriatic acid into the bowl. Add 1 cup of water to the acid. Swirl the bowl around a bit to mix it.

3. Apply the mix to the concrete on your car with a sponge. Let the liquid soak the dried concrete for several seconds, then wipe and scrub the concrete off of the car.

4. Rinse the area with water.

Tips & Warnings

• Wear protective eyewear, mask and rubber gloves.
