Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to clean a sleeping bag [title] Use soap formulated for a down-filled sleeping bag, if applicable. [step] Only use soap made for washing down material, as it will be gentle on the stuffing in the sleeping bag. Avoid using regular detergents and soaps, as they are too harsh and can damage the down.

Ending1: [substeps] Look for a food and water substitute that is nonabrasive. Avoid using water or soaps marked for care after each use, as these will be too abrasive to work on the bag. Ending2: [title] Reach into your sleeping bag and remove any loose stuffing. [step] Don't just empty any of the contents out onto the floor or have a ball full of loose stuffing around the bottom of the bag. Ending3: Not only will your tarp or bag absorb the moisture and leave behind stains, but you can also stain the blanket or cover with chemicals that have a worse effect. [substeps] Don't use mineral spirits as they stain easily. Ending4: Look for down soap at your local hardware store or online. [substeps] Follow the instructions on the label to determine how much soap to use.
