Yes, you are permitted to bring a small, personal-sized can of Lysol or other aerosol disinfectant sprays into the Disneyland theme parks in 2026. While Disney has strict rules against "highly flammable" substances, standard personal hygiene items and cleaning sprays are generally allowed through security. However, there are two important "common sense" rules to follow: first, the container should be a reasonable "travel size" rather than an industrial-sized jug; second, you must be respectful when using it. Cast Members may intervene if your spraying negatively impacts the experience of other guests (e.g., spraying in a crowded, enclosed ride queue or near someone’s food). In 2026, with Disney's already enhanced cleaning protocols, most guests find that a small pack of disinfectant wipes is often more convenient and less intrusive for quickly sanitizing high-touch surfaces like stroller handles or table tops without drawing unwanted attention from security.
