There are also ones meant to be used with American-type masturbators like the Fleshlight. I don't know if they'll degrade Japanese onaholes. This particular one is made of purified cornstarch

I just use talc, but the one in that picture is supposed to be antibacterial. I don't really trust cornstarch since the bacteria could probably use it as food and multiply (it's made of corn!).

Yeah, the powder in the first post is a special Magic Eyes powder with zinc & silver ions. They have a whole new line of "Open My XXX" themed onahole cleaning products.

I actually had that stuff in my most recent order from NLS and just received it! The powder bottle is a bit smaller than I imagined… I think I'll stick with baby powder since it's cheaper, smells nicer, and it's sold everywhere. The spray is nice so I think I'll continue to use that. As for the cleaner, I still prefer Ona Clean (http://en-nls.com/pict1-27929). That stuff also has silver ions, but not the zinc and copper (although I wonder if it actually makes a difference since they all seem to function on the same principle… http://en.wikipedia.org/wiki/Oligodynamic_effect). I didn't try the lube because I was a bit worried about exposing myself to infection after reading a review of a similar product: https://blog.onahole.eu/ag-lotion.html

Thanks for the input, I was considering the new product line for purchase.
