8. Hygiene and cleaning protocols (across types)

Hygiene is as important as accuracy when thermometers pass between family members. Different thermometer types need different cleaning routines. For oral and rectal digital probes, use single-use probe covers when available and wipe the probe with a manufacturer-recommended disinfectant after each use; avoid submerging electronics. Ear thermometers with disposable probe tips reduce cross-contamination, and you should change tips after each person. Non-contact forehead thermometers still need their sensor lens cleaned occasionally; use a soft cloth and a gentle alcohol wipe without scratching the optical surface. For strip thermometers, discard after the user has had a fever episode or follow single-user guidance. Store thermometers in a clean case away from direct sunlight and heat, and keep spare batteries and probe covers on hand. Simple practices—label a thermometer for one person in a multi-generational home, teach older children to use covers, and clean devices promptly—make a big difference. These small steps are easy to adopt and marry well with family habits, whether you learned care tips from dadi or a clinic nurse.
