This chair was brought to me after the customer's friend tried to cane it by placing masking tape around the seat to mark the strands of cane and gave up part way. The tape was left on the chair for quite a while. Some of it came off, but left a heavy residue which is very difficult to remove. A section of the tape on the front of the chair actually dried into the finish and could only be removed by soaking in oil and bringing up the finish with it. Tape residue will have to be worked off the chair so that the finish isn't damaged further.
Never ever put tape on finished wood.
