It wouldn't hurt to try, but depending on the type of plastic the cutting board is made of, it may not help smooth the surface.

yes you can do that however, it will not achieve the smooth surface that it had from the time of purchase. This is because of the moulding process. It should be noted though that if you do attempt to sand this down you will have the issue of the surface being more open to retaining germs. This is because the surface will in effect have micro scores in it which will make the surface course. These will act like small trenches filling with food microbes.

It might be wise to scrap off board and purchase a new one. This is because by the time youve purchased the abrasive materials in about 4 grit sizes you will have spent more than the board is worth. A good wooden chopping board is well worth the investment especially if its made of beach or steamed beach which is quite tough and these can be sanded with decressing abrasive sizes and sealed with a vegetable based oil to bring them back ot their orginal quality.

No, I would not recomend using pine in a cutting board at all. You can use soft maple from the big box stores to keep cost down. Hickory may be even cheaper.

Polycarbonate is a material similar to acrylic. It is a thinner and lighter alternative to plastic. Polycarbonate is also impact resistant and because it is a tougher material, it tends to be more scratch resistant as well.

Polycarbonate cutting boards are good, because of the impact resistance. It's also good because it is nonporous, and cleans easier. Because of the nonporous surface, it does not harbor bacteria. Most polycarb cutting boards are treated with an antibacterial agent.

Non Porous boards, like plastic and glass, are easier to clean and disinfect. Glass however doesn't treat you knives very well and are not user friendly. One slip in the kitchen and it could be quite dangerous too! Whether you decided to use Plastic or Wood, always wash with warm soapy water afterwards and bleach to kill any bacteria that may still be lurking.

It depends what you will be using the cutting board for.
