This is what it's all about.

Olivier started to produce his own natural household products a few years ago, following his father’s example of not using chemicals and using natural products instead: «I am very happy to start this project because it is possible to produce natural, environmentally friendly and also very efficient household products. As someone who loves cleanliness, I put all my energy into developing and testing our products. I want to make them available to as many people as possible to reduce our negative impact on the environment and to contribute altogether to their improvement».

For David, it is a matter close to his heart to work on the great challenges of our time and to find pragmatic and sustainable solutions to concrete problems: «I am convinced that especially for us young people the environment will become more and more important. I see our joint project Clean Twice as a great opportunity to do something concrete for our environment and thus for all of us in an effective and sustainable way. As a student at ETH Zurich, I use the opportunities offered by science in order to find new, ecologically sound alternatives through mutual exchange.

Clean Twice helps you to minimise your ecological footprint with natural household products in reusable containers. This is how we want to change consumer habits. Sustainability, environmental friendliness and transparency are our top priorities. In concrete terms this means for our products:

  • replacing plastic bottles with reusable glass or other ecologically sound materials,
  • local production and organisation of permanent reuse of glass and other containers,
  • Development and further development of household products and cosmetics based on natural ingredients
  • and minimising the overall environmental impact of all our products (in particular avoiding waste and plastics and reducing emissions).

As the first action for you and the environment, we have decided to offer hand disinfection gel in high quality, handy, beautiful and permanently reusable glass bottles, as disinfectants are indispensable in today’s situation. By replacing chemical products in plastic with natural gel in reusable glass bottles, we can have a great positive impact on our environment.

In combination with our refill concept, we can already demonstrate that sensible alternatives to various conventional household products in plastic are conceivable and practicable. And that even for all of us!

Our next household products:

Clean All (all-purpose / kitchen cleaner), Clean Bath (bathroom cleaner) and Clean Window (window/glass cleaner) on a natural basis in high-quality, robust and reusable glass or metal bottles.

Later we will develop other necessary household products as well as cosmetics - also on a natural basis.

As with all our products, you pay for the bottles/containers only once; later only the product itself (refill). In this way, we avoid waste, unnecessary transport and emissions. And you avoid unnecessary costs.

Our project is special because ...

Clean Twice is not only our project but also yours. Because only together will we succeed in changing consumer habits and keeping the planet livable for us and future generations.

Our commitment to you and our environment:

  • To use glass or alternative materials in a way that is ecologically much more sensible than plastic,
  • to always offer the best sustainable alternative to conventional products and packaging based on current research results,
  • develop natural products that are at least as efficient as corresponding chemical products
  • and at prices similar to those of traditional products.

To make our joint positive impact on our environment even more tangible and greater, we invest a portion of our sales in projects to protect and improve the environment.

Now is the time to act concretely and together and to change our consumption habits as quickly and sustainably as possible! In this way, we can not only slow down the ongoing environmental destruction but also contribute to improving the environment.

«Each and every one of us has an important role to play. […] I can only encourage everyone to think big and act now. «We simply cannot waste any more time, the only limit is our willingness to act, and the time to act is now.» - Prince Charles, Great Reset (WEF 2020).


This is what we need backing for.

Thanks to your support, we will be able to manufacture our first products as soon as possible with the help of a professional production facility in the Zurich area. We are already looking forward to being able to produce ourselves and are thus well prepared for increasing demand.

We look forward to your support for

  • the development and production of our hand disinfection gel and our Clean Home cleaning products, and in future also for cosmetics,
  • the reusable glass bottles and, where appropriate, other types of container
  • and the investment in our own production, filling and processing plant.

When we have reached our target of CHF 25,000, the additional money will be invested in

  • the establishment of a network of further processing installations,
  • and in the further development of techniques that enable us to completely remove plastics from our products as quickly as possible.

We just need YOU and your contribution to start Clean Twice now and together we can have a big positive impact on the environment.

David: «In order to meet the great challenges of our time and in particular to counteract climate change, we need the willingness to question our daily habits and above all to take action together. to find solutions.»

Olivier: «This is not just a project of David and me, it is a project for all of us. Together with you, we can achieve much more!»
