Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to clean oven glass [title] Create a baking-soda scrub. [step] Mix a solution that's 3-to-1 water to baking soda in a shallow bowl until the soda dissolves. It will have the texture of a loose paste.

Ending1: [substeps] If you don't have the strength or patience to make something all-natural (or you prefer the flaky, bubbling texture), add baking soda to your scrub. Make sure to get all the sides of the glass clean-you don't want to find a glob of soda sitting on the glass. Ending2: Open your oven, and spread this mixture on the glass of your oven door. You can use your fingers to spread it on every bit of the glass. Ending3: [substeps] This mixture is designed to be mixed with a liquid once it dries. To make a scrub: mix 3-parts baking soda with 1 part salt and add these two together until dissolved. Ending4: Apply the mixture to your oven glass as you go-a rag or sponge should work. Keep the scrub on tight to avoid scratching the glass.
