The answer to 'why is my countertop discolored' is that there can be several common causes, including spills, stains, or damage to the surface. Discoloration can happen over time due to exposure to heat, acidic foods, or harsh cleaning products.
If the discoloration is mild, you may be able to remove it with a gentle cleaning solution and some elbow grease. However, if the damage is more significant, you may need to consider resurfacing or replacing the countertop. It's always best to address discoloration promptly to prevent further damage.
