The correct way to clean and sanitize shampoo trays and bowls after each use is by using soap and water, or an alternative detergent. This option is the most effective in removing any dirt, debris, or bacteria that may be present after use. Replacing the trays and bowls with new ones (option A) is not necessary and can be wasteful and costly. Covering with a plastic sheet (option B) may not effectively remove the debris and bacteria, and can also create a breeding ground for bacteria. Inspecting for damage (option D) should be done regularly, but this does not effectively clean and sanitize the trays and bowls. Therefore, the most appropriate and efficient option is to cleanse with soap and water or other detergent (option C).
