How to Remove Oil on the Concrete With TSP
- 1). Protect yourself against the TSP by wearing long rubber gloves and safety glasses.
- 2). Prepare a TSP paste to draw out the oil. Stir together 1 cup of warm water, 1 oz. of TSP and 1/2 cup of talc powder in a container.
- 3). Disperse the paste over the oil stain using a trowel. Cover the oil-stained concrete completely. Wait for the paste to dry and harden.
- 4). Detach the dried paste from the concrete using the trowel. Scrub off stubborn paste fragments using a nylon brush.
- 5). Sweep up the loosened paste particles with a broom.
- 6). Examine the concrete for dark blotches. If the oil remains, fill another container with 1 gallon of hot water. Stir 1 cup of TSP into the hot water.
- 7). Pour the diluted TSP onto the oil-stained concrete. Let the liquid permeate the oil for 20 minutes.
- 8). Scour the affected concrete with the brush to dissolve the remaining oil.
- 9). Rinse the concrete thoroughly with fresh water.
