Sinituote is a Finnish family company that manufactures and markets home products, SINI cleaning and clothing care products, and the KUNGS car care range.

We have our own testing laboratory, where we test the properties of our products and materials. The laboratory?s equipment includes a microscope, product-specific testing gear, and a weather-exposure cabinet.

In our product development, we perform durability and functionality testing in our test laboratory to discover the best possible solutions regarding the materials used. Our brush products have all passed a durability test consisting of tens of thousands of brushing motions on various kinds of surfaces.

Weather-exposure testing enables us to optimise a product?s durability at extreme freezing temperatures as well as in constant sunlight. We select the materials, colours, and technical solutions for our products carefully, to ensure that the product can withstand years of use in demanding conditions.

All stages of production at our factory incorporate systematic quality monitoring, and we test all purchased components and materials before commencing production.
