Start with the cleaning code
Furniture tags may indicate water-safe, solvent-only, or professional-clean-only care. Never assume that because a portable machine is sold for upholstery it is appropriate for your particular sofa.
Test an inconspicuous place
Even compatible fabric can change color or texture when wet. Test your intended solution and process on a hidden area first, then let the test dry fully before proceeding.
Use less liquid than you think
Over-wetting can create longer drying times and may leave moisture in cushions. Follow the machine and fabric maker’s instructions and make extraction passes if indicated.
Know when not to DIY
Large stains, delicate textiles, persistent odors, and water damage may need a professional. A small spot-cleaner is useful, but it is not a universal restoration machine.
