Makeup brushes absorb foundation, powder, and oils, which accumulate over time and can cause skin issues. Cleaning brushes manually often fails to remove all residues, especially in the base. Ultrasonic cleaning is ideal for thorough brush maintenance. Gentle vibrations in the cleaning solution loosen and remove dirt and makeup residues without damaging bristles.

Watches are exposed to sweat, dust, and skin oils, particularly in metal and rubber bands. Dirt accumulates in tiny gaps and joints, affecting appearance and potentially reducing longevity. Cleaning manually can be tedious and risky for delicate surfaces.

Silver tableware adds elegance to dining, but it easily tarnishes due to oxidation and contact with acidic foods. Over time, forks, spoons, and knives lose their shine and develop dark spots. Manual polishing can be tedious and may not reach grooves or engraved designs.

Electric shaver heads are exposed to hair, skin oils, and shaving creams every day. Over time, residues can accumulate inside the blades and foil, reducing cutting efficiency and potentially causing skin irritation. Manual rinsing often fails to reach the small gaps between blades and foil, leaving dirt trapped.
