I have been using it on the wood stove for years. Very good. In areas where the "enamel of the stove" has burned away completely, such as around the double doors and above and below the wood entry door where the air adjustment regulators and valves are, over the years, besides being burned, they could have also "rusted" (if you understand me), it makes it look like new.
There are no instructions in Greek.
I apply it with a non-absorbent cloth or good quality vetex because it wears off from rubbing, and after 1-2 hours, I go over it again with another soft cloth to remove the black residue it leaves on your hands if you don't wipe it off, and also to make it shine even more.
In areas (for me) where we don't touch or come into contact, e.g., the flue, I don't wipe it.
There is minimal smell, almost for half a day if you light the stove 3 hours after applying it (if you do it in the morning and light it in the afternoon with an open window until the evening, you’re good to go).
You can also have a soft cloth lightly coated with oil (minimal) for better polishing - it takes longer to dry or gives off a stronger smell on the first lighting if done immediately after application. If you do it beforehand, e.g., a week ago, there’s minimal smell at the beginning.
(In the photo, the spot on the valves that burns. Here, only the door has been affected after 1 week of daily use). I ran out of the cream and didn’t have any more for the valves.
I maintain it every year.
