Unexpectedly Good
This product doesn't smell of anything, and behaves just like water when sprayed onto steel so I was sceptical of its cleaning abilities. But it does clean fantastically. I used camellia oil on a shinken which left spots of oil over the surface which I couldn't remove with washi paper alone. But one application of shinken cleaning fluid and a rub down with sword paper left my blade clean, unblemished and ready for re-oiling (with choji oil this time-don't use camellia oil on a shinken!)
