The answer to 'cleaning schedule for upholstery' is that upholstery should be cleaned every 12-18 months, or more frequently if it sees heavy use or shows visible signs of dirt and stains. Regular cleaning helps maintain the appearance and extend the life of your upholstered furniture.
The specific cleaning schedule will depend on factors like the type of upholstery, the amount of use it gets, and whether there are pets or children in the home. Lightly used upholstery may only need cleaning every 18 months, while heavily used pieces may require cleaning every 12 months.
