Start with a clean shower. Each day spray a light mist of Sparkle Daily Shower Clean over shower screens and tiles from bottom to top while the shower screens are still wet. No need to rinse, scrub or wipe. Sparkle Daily shower Clean's pH neutral formulation means that it should not damage delicate surfaces. However we recommend that you test in an inconspicuous area prior to use. For first application, leave for 2 minutes, then wipe with a clean, damp cloth and rinse.
