Hi there, I am having an oily ring around my hot tub. We are a family of 6, and we use it a fair amount you could say. Any tips to get the ring off without scrubbing it hard all the time ? We use a microfibre cloth but it takes so much effort. My two daughters use body oils and my husband showers 99% of the time before using it but sometimes he doesn't. Thank you !
