When your sharpening stone is clogged (the so-called glazing effect), it needs to be cleaned. The Foss sharpening stone cleaner is the perfect product for this. It opens the stone’s pores, and dust and bits of steel will disappear. Your sharpening stone is ready to do its job again.
Mix the cleaner with water (1:40).
Keep the stone submerged in a closed container for several hours. Dry the stone before you start sharpening. Add some Foss sharpening oil, if you like.
The content of a bottle is 250 ml.
