The answer to 'why is my kitchen stained' is that kitchen stains can be caused by a variety of factors, including spills, grease buildup, and improper cleaning. Common symptoms include discolored countertops, stained backsplashes, and dingy cabinets. Fortunately, there are often simple solutions to address these issues.
For minor stains, a thorough cleaning with a degreasing cleaner or baking soda and vinegar solution may be all that's needed. For more stubborn stains, you may need to use a specialized cleaner or attempt some light scrubbing. If the stains persist or cover a large area, it's best to call in a professional cleaning service to assess the situation and provide a more comprehensive solution.
