Teakworks4u strongly recommends performing routine cleanings when you clean your shower or bathroom. A deep clean is recommended on a yearly basis to keep your piece looking new. It is also recommended to clean the underside of your mat or bench inspecting the rubberized footing each time you clean or re-oil it. Replace the rubberized footing if you start sensing any slippage or movement. Remember that Teak has a slip-resistant surface, but a soapy build-up can compromise this, so it is important to clean your Teak regularly. NOTE: Do not use a power washer.
