A sofa can look clean and still hold years of dust, sweat, food crumbs and dust mites. In Dhaka air that builds faster. If someone starts sneezing ten minutes after sitting down in the evening, the problem is inside the sofa.
We fabric-test first (to check nothing bleeds), dry-vacuum, then shampoo or steam according to the fabric, and finish with hot-water extraction — the machine pulls the water and the dirt back out rather than leaving it in the foam. Leather sofas get a dedicated leather cleaner and conditioner instead.
Drying: 4–6 hours depending on the seat; faster with fans running. For large carpets we bring air movers. Pricing is per seat and per square foot of carpet, quoted before we start.
