Plasticizer Migration? - FineWoodworking
Start with a very fine compound. Long strokes, back and forth, with the grain, on the entire top. Mist with a little water from a spray bottle helps. Back and forth 2 or 3 times. Wipe it off and see how it looks.--That would be my first approach. It will bring out more shine than originally there, but the damage will hopefully disappear.
repair advice needed about wood table damaged by plastic cover
What you are probably seeing is a phenomenon called "plasticizer migration." The way I explain it is that the chemicals in the plastic to keep it soft and flexible migrate into the finish and do the same there. There is no saving the damaged finish, it must be removed. What repair is needed depends upon the extent of damage.

In order to make plastics and lacquers, which are a type of plastic, more flexible (that is, less brittle), plasticizers, which are a type of oil, are added. When plastics are placed on a lacquer surface, especially under some weight, they can stick to the lacquer and sometimes cause it to turn white.
How common is the issue of plasticizer migration? : furniture
I’m in the market for new furniture and need a large sectional with a matching recliner chair. For now we’re looking at the ones at Big Lots but I’m not too sure about the quality of the furniture there. I’m needing it to be gray, microfiber, and seat at least 6.
The Craftsman: Table Leaf with Plasticizer Damage - Blogger
Table Leaf with Plasticizer Damage. This leaf belongs to a beautiful table that has suffered 'plasticizer' damage. You can see from the photo that it has a strange 'oily' appearance in the finish. This happened because the owner of the table put a plastic 'table cloth' over it to protect it, and then left in on for a while.

- Do plasticisers migrate from polymers to a gas phase?
- This paper addresses the kinetics and predictions of plasticiser migration from polymers to a surrounding gas phase, an important issue for plastic and rubber products exposed to high service temperature conditions and during accelerated ageing and testing.
- How does temperature affect the plasticiser migration process?
- In addition, other ageing processes, such as the oxidation and annealing of polymers, are also accelerated at high temperature. 50 Any effects of these processes on the plasticiser migration process should be determined to yield a correct prediction.
- How does surface modification prevent plasticiser migration?
- In addition, surface modifications, such as surface coatings and crosslinking, are commonly employed to suppress plasticiser migration. 1, 72, 73 The modified surface layer acts as a barrier to the plasticiser and isolates the plasticiser from the exposed medium, preventing its migration. 1, 74
- What causes plasticiser migration in biopolymers?
- Studies have shown that the migration behaviour of plasticiser in biopolymers is often complex. This is caused by: (i) cold crystallisation during service/ageing, (ii) phase separation between the plasticiser and the polymer, and (iii) hydrolysis and interactions with water.
- What is the evaporation rate of plasticiser?
- Second, the plasticiser evaporation rate from polymer surfaces is similar (on the same order of magnitude) as the rate from their pure liquid state, indicating that the constant plasticiser concentration on the surface is close to that in the pure liquid (100%).
