Hello, I’m looking for a professional to thoroughly clean a queen-size mattress. The job would involve removing stains, deep vacuuming, and sanitizing the surface. I’d prefer eco-friendly cleaning products and tools, and I’d like the technician to arrive with a portable steamer if possible. The mattress is in a guest room that’s rarely used, so any lingering odors should be addressed. Please advise on the expected duration and aftercare tips to prevent future stains. Ideally able to start in the morning and complete the job within a few hours.
