Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to warm a horse's bit [title] Dunk in hot water, then wipe dry. [step] Heat water until it's just begun to steam, then bring it over to the stall in a bucket. Place a safety hook over the bucket and drape the bridle over it, making sure not to let the leather touch the water or the ground.

Ending1: Dunk the bit for 10-15 seconds in hot water, or 1-2 minutes in lukewarm water. Wipe the bit down with a cloth to dry it. Ending2: Try to keep your head at least six inches from the water. The halter and bridle should be crimped, not tightened, to avoid fraying. Ending3: [substeps] You don't want the bridle to get hot. If this happens, you need to bring a band-aid or thick covering of newspaper over the cloth. Ending4: Smooth out any wrinkles so the bridle stays in place. [substeps] When you go to wash the bridle, look in the mirror to see if it fits.
