I just finished painting my cabinets white and to finish it off, I put three coats of polycrylic on top to make them more durable. I placed the cabinet doors back on yesterday. Today, while making a berry smoothie for breakfast I splattered some on the cabinet door, but didn't notice it for a couple of hours. When I did, I went to wipe it off, but it left a stain on my white door that will not come off.
1) Is there anything I can do that will remove the stain without harming the polycrylic?
2) How did this happen? I figured polycrylic would wipe right off.
3) What should I do now to make sure future messes won't stain the cabinets?
