Leather Care Interval Calculator

Get a conditioning schedule matched to leather type and climate.

Tool Operation Area

Builds a maintenance interval and care plan from leather type, usage frequency and the climate the item lives in.

How It Works

  • Each tannage has a baseline conditioning interval reflecting how quickly its fats and finish deplete.
  • Daily-carry items are handled and flexed constantly, so the interval shortens; occasional items stretch it out.
  • Extreme climates — very dry or very humid — pull the interval in further.
  • Cleaning runs roughly three times as often as conditioning, since surface dirt accumulates faster than oils deplete.

How to Use

  1. 1Pick the tannage; if unsure, vegetable-tanned leather darkens with water and chrome-tanned does not.
  2. 2Set an actual calendar reminder for the returned interval.
  3. 3Always test any product on a hidden area first.

FAQ

Can I over-condition leather?

Yes. Excess oil breaks down fibre structure and leaves the leather limp and greasy.

What about rain?

Let it dry naturally, then condition once fully dry — never before.

Does patina need conditioning?

Light conditioning preserves patina; heavy oiling flattens the colour variation.

How do I store leather goods?

Cool, dark, ventilated, stuffed to keep shape, never in a sealed plastic bag.
