Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to remove primer [title] Pour vegetable oil into a dish. [step] Measure out enough vegetable oil to cover the primer stain on your skin and pour it into a small dish. [substeps] Most primers are oil-based, so plain water won't be effective against them.

Ending1: You should also use a low-evaporation method so that you don't have to worry about the oil warming up too much. It can also work in a pinch, such as microwaving or using very hot water. Ending2: As oil-based products, though, they are oil-soluble and can usually be lifted with the use of additional oil. A little will go a long way, so you may only need 1 to 3 tbsp (15 to 45 ml), even when you need to remove a large primer spot. Ending3: [title] Pour in 2 tablespoons of black pepper. [step] You can use either fresh or dried pepper, but fresh peppers are more potent than dried peppers. Ending4: If you prefer to use only oil, use one ounce of vegetable oil for every 1 cup (250 ml) of oil you own. [title] Let the oil absorb for 10 minutes.
