Which type of cleaning product is NOT typically used on finished wood surfaces?

High alkaline cleaners are not typically used on finished wood surfaces due to their strong pH levels, which can damage the protective finish and the wood itself. Finished wood surfaces require gentle, pH-balanced cleaners that maintain their protective coatings and natural sheen. Alkaline cleaners can strip finishes, lead to discoloration, and affect the wood's integrity over time.

In contrast, oil-based polishes are designed to nourish and protect finished wood surfaces, leaving a subtle shine while enhancing the wood's natural appearance. Dry solvent-based cleaners can effectively remove dirt and grime without damaging the finish, making them suitable for use on wood surfaces. Biocides might be used to address specific issues like mold or mildew but are not a standard cleaner for regular maintenance on finished wood. Therefore, high alkaline cleaners stand out as the inappropriate option for maintaining these surfaces.
