I really recommend Precious Stars Pads, I got my cloth ones there 4 years ago and they are still going strong. So much better for the environment and your wallet in the long run! I usually wear them as a back up when using a cup but sometimes I just use them on their own, after which I will soak them in cold water and Vanish powder before rinsing and washing in the machine. As already mentioned, don't use fabric softener on them as it can effect the absorbency, so for that reason I usually wash along with towels or my gym leggings which I also don't use softener on.
I know not everyone can wear a cup but there are so many more brands out there than Mooncup, and so while one brand of cup might not suit you another one could be great. I use a Lena Cup and love it, and there are also Saalt cups, Ruby cups, Lily cups, Lunette cups, the list goes on!
