There is some discoloration on one of my cabinets from grease. Will this cover it or is there another option such as ordering a replacement door?

Thanks for reaching out to us. I am not certain a touch up kit will cover a grease mark. A replacement door is available as special order from Lowe's, if the cabinet is a current size that we offer. Your Lowe's Associate would be able to assist with the order and provide you with the cost. Thanks ~ Sherri
