Nobody remembers when the kitchen cloth was last changed. Enter the date it went into use and the replacement interval you have settled on, and the tool returns the due date, how long is left from your reference date, how many swaps that works out to in a year, and the second and third due dates. If you rotate several cloths, run each one with its own start date.
Dates are advanced by year, month and day components, so month ends and leap years do not throw the result off. Swaps per year is 365 divided by the interval you entered, shown to one decimal place. If the reference date is already past the due date, the tool says how many days overdue it is instead (as of October 2026).
No authoritative recommended replacement interval for dishcloths or sponges is offered here. Widely repeated figures exist but are not confirmed in an authoritative source, and the right interval depends on how the cloth is used and what it is made of. Boiling temperature, boiling time and sanitizing methods are left out for the same reason. Follow the product instructions and the manufacturer guidance first.
Frequently Asked Questions
No authoritative recommended interval is offered here. Widely repeated figures exist but are not confirmed in an authoritative source. Enter the interval you already follow, or the one printed in the product instructions, and the dates are calculated from that value alone.
No. No authoritative value for boiling temperature or holding time was confirmed, so this page handles dates only.
The tool shows how many days overdue it is instead of time left, with a short note. If the reference date equals the due date, it reads 0 days.
