Sansol introduces a revolutionary approach to bathroom cleaning. Its highly concentrated, foaming formula adheres to vertical surfaces, effectively removing soap scum, body fats, oils, hard water deposits, rust, urine stains, dirt, algae, and mildew. For optimal results, apply Sansol to surfaces and allow it to sit for several minutes before thoroughly rinsing with running water. Note: Avoid using Sansol on painted surfaces, as its concentrated, mildly acidic formula can damage paint and metal surfaces containing aluminum, brass, or copper, even when diluted.
