Wet cleaning refers to a process that uses water and specialized detergents to clean fabrics, rather than traditional dry cleaning methods that use solvents. For your comforter, this typically means you can wash it in a washing machine, but you should follow the care instructions closely.
First, check the size of your comforter. If it's too large for your home washer, consider taking it to a laundromat with larger machines. Use a gentle cycle with cold or warm water, and a mild detergent to avoid damaging the fabric. It's also advisable to add a couple of clean tennis balls or dryer balls when drying to help fluff the comforter and prevent clumping.
If you're unsure or if your comforter is made of delicate materials like silk or down, you might want to consider hiring a professional cleaning service. The cost for professional cleaning can range from $20 to $50, depending on your location and the size of the comforter.
As a next step, check local dry cleaners or laundry services for quotes on wet cleaning your comforter.
