I'm looking for a professional to thoroughly clean a queen-size mattress in my shared flat. The mattress is about 5 years old and shows some light staining from spills. I’d like a deep cleaning that includes stain pre-treatment, steam or hot water extraction, and a fresh deodorizing finish. Please confirm you have the proper equipment and safety data sheets. Flexible on timing, but I’d prefer a weekend slot if possible. Vacuuming and removing any visible debris before cleaning is a must. Thank you!
