Blind people know when to stop wiping primarily by relying on tactile feedback and heightened sensory perception. They assess cleanliness by feeling the texture of the toilet paper after each wipe; when the paper no longer has residue and the sensation indicates cleanliness, they stop wiping. The skin in the area is highly sensitive, which helps detect any remaining matter. Using moderately textured or standard-quality toilet paper enhances this tactile feedback, making it easier to determine when they are clean

. Additionally, many blind individuals use water-based cleaning methods such as bidets, which provide a thorough clean with less wiping needed. When bidets are not available, tactile sensation remains the main method

. Some also use assistive hygiene tools or carry wet wipes for additional cleaning and to avoid contaminating other items like canes. Regular hygiene education and sensory training improve their ability to judge cleanliness effectively

. In summary, blind people rely on the feel of the toilet paper and the sensitivity of their skin to know when they are clean and can stop wiping. This method is supported by sensory awareness and sometimes aided by assistive devices or water cleaning methods.
