The answer to 'countertop discolored' is that there are several common causes, including stains, etching, or discoloration from spills, heat, or improper cleaning. Symptoms may include faded, dull, or uneven coloring on the countertop surface. Fortunately, there are often DIY solutions, but in some cases it's best to call a professional cleaning technician.
For minor discoloration, you can try cleaning the countertop with a gentle, non-abrasive cleaner and soft cloth. If that doesn't work, you may need to use a specialized countertop cleaner or polish. For more stubborn stains or etching, you may need to sand and reseal the countertop. However, for significant or widespread discoloration, it's often best to consult a professional cleaning service to properly assess and treat the issue.
