Red Marvel Bathroom Cleaner is a Canadian made concentrated bathroom cleaner ideal for removing soap scum and some mineral deposits resulting from well water systems (designed specifically to remove soap scum, mineral deposits and rust). Without question, it is one of the best bathroom cleaners on the market today (without any noxious or toxic fumes). Red Marvel is for use on all fixtures within the bathroom including shower stalls, chrome fittings/taps/faucets, toilets and sinks. It is safe on virtually any surface including porcelain, fiberglass, acrylic, ceramic tiles, glass shower doors and chrome (great for use on toilets, shower stalls, bath tubs, bath sinks, shower doors, chrome taps, etc). NOT TO BE USED ON MARBLE, CULTURED STONE, SLATE, WOOD OR ALUMINUM SHOWER DOOR FRAMES. Red Marvel, due to its mild acid content (phosphoric) should not be used on granite, quartz or marble surfaces as it may etch the surface if allowed to sit too long. If contact occurs, rinse immediately. Can be used on chrome if rinsed off immediately. Red Marvel is Septic Tank Safe/Holding Tank Safe and contains no petroleum based solvents or dyes. Cruelty Free and absolutely no animal based ingredients. Directions: - For best results, squeeze a 4” circle (about the diameter of your palm) onto a sopping wet rag and spread evenly over the surface to be cleaned. Once applied, simply allow it to penetrate/work for about 2 minutes and then rinse off. Toilet bowls and urinals: - Apply concentrated product and spread with bowl swab taking care to get under the rim. Allow to sit for 3-5 minutes and flush. Drinking fountains, ceramic tile and floors: - Dilute 1 part Red Marvel with 5 parts water. Spray or mop diluted product on surface and swab or agitate if necessary. Allow to stand for 5-10 minutes and rinse thoroughly. Color may vary. Available in our 500ml bottle deposit ($1.50) or in an upcycled container. Return your bottle deposit in store for a refund.
