True or False: It is recommended to use an oil solution when treating finished wood to avoid altering appearance.

Using an oil solution when treating finished wood is indeed recommended to avoid altering its appearance. Oil solutions are less likely to leave a noticeable residue or change the texture and look of finished wood compared to other treatment methods that may involve harsher chemicals or techniques. This is particularly important in maintaining the aesthetic quality of the wood, especially in furniture or fixtures where the visual finish is paramount.

The use of oil not only helps to treat any existing infestations gently but also protects the wood without distorting its finish. This aligns with best practices in pest management where maintaining the integrity of the wood's appearance is essential in ensuring customer satisfaction and preserving the wood's value.
