What are the common disinfection methods for ceramic tableware?
10 Apr,2026
The disinfection methods for ceramic tableware need to balance safety and effectiveness. The following are common methods and key operation points:
1. High-Temperature Disinfection (most commonly used, highly effective)
Boiling Disinfection
Operation: Immerse the tableware in cold water, bring to a boil, and cook for 5-10 minutes (suitable for underglaze colored/plain tableware; avoid long boiling for overglaze colors to prevent pigment damage).
Note: Do not boil damaged tableware to avoid bacteria remaining in cracks.
Steam Disinfection
Tools: Steamer, steam disinfection cabinet, or microwave (with steam function).
Operation: When steam temperature reaches 100℃, disinfect for 10-15 minutes, ensuring tableware is not stacked and steam fully contacts the surface.
Oven Disinfection
Applicable situations: High-temperature resistant ceramics (marked "oven-safe").
Operation: Preheat the oven to 120℃, place dry tableware inside, maintain for 15-20 minutes, then remove after cooling (avoid sudden cooling to prevent cracking).
2. Chemical Disinfection (for emergencies or when high temperatures are inconvenient)
Chlorine-containing Disinfectant Soaking
Ratio: 1 liter of water with 5-10 ml of chlorine disinfectant (such as 84 disinfectant), stir and soak the tableware for 15-30 minutes.
Follow-up: Rinse thoroughly with clean water 3-5 times to avoid chemical residue.
White Vinegar Disinfection
Operation: Mix water with an appropriate amount of white vinegar (ratio 10:1), boil and soak tableware for 5 minutes; it can soften scale and inhibit bacteria.
3. Ultraviolet Disinfection (auxiliary method)
Tools: Ultraviolet disinfection cabinet or dishwasher with ultraviolet function.
Operation: After wiping the tableware dry, place inside and turn on UV irradiation for 30 minutes (ensure UV fully covers and no dead angles exist).
4. Dishwasher Disinfection (combines cleaning and disinfection)
Requirements: Dishwasher must have a "high-temperature disinfection" mode (water temperature ≥70℃), wash time ≥30 minutes; can simultaneously clean and sterilize.
