The most common clue in clicker puzzles is stainless steel soap: a smooth, egg-shaped piece of metal that neutralizes stubborn odors on the skin.

What is it for and how does it work?

Odor molecule binding: It primarily removes the smell of garlic, onions, fish, and raw meat from hands.

Chemical reaction: Sulfur compounds are responsible for the smell of onions. When you rub damp steel against your skin, the

sulfur molecules form a chemical compound with the chromium oxide on the steel surface. This causes the odor molecules to migrate into the metal.

Not ordinary soap: It doesn’t disinfect, doesn’t lather, and doesn’t remove grease or dirt—it simply eliminates odors.

How do you use it correctly?

With cold water: Hold the bar of soap and your hands under running cold water and rub your hands together for 30–60 seconds. The warm water opens the pores and allows odors to penetrate deeper.

After cleaning: First, wash your hands with regular soap to remove grease and dirt, and then use the bar of soap to deodorize them.

You can achieve the same result for 0 forints by rubbing your hands under cold running water against a stainless steel tap or a tablespoon.
