A 100g soap bar lasts 60 to 80 washes with proper use. That is two to three times longer than a 250ml bottle of shower gel. But only if you store it well. Most soap runs out faster than necessary for one simple reason: it stays wet.
Why dry storage is so important
Soap dissolves in water. The wetter it stays, the faster it dissolves. A soap bar sitting in a flat, wet soap dish becomes soft, smaller and runs out much faster. Dry storage is the most important step for a long lifespan.
The best ways to store soap
Bamboo soap dish — the bamboo dish has an open structure that lets the soap dry between uses. Moisture drains away and the soap dries quickly. The most effective and sustainable solution.
Sisal soap bag — the sisal bag lets the soap hang and dry. Also works as a scrub. Handy for people who want to grab the soap directly without a dish.
Travelling: aluminium soap tin — leak-proof and compact. Let the soap dry before putting it in the tin.
Extra tips for a longer lifespan
- Keep the soap out of the direct water stream in the shower
- Always let the soap dry after use
- Have multiple soap bars? Let the rest cure in a dry place. Soap improves with time: harder, milder and longer-lasting
- Cut large soap bars into pieces and use one piece at a time
