The SPONTEX Gratt & Flex sponge is an innovative and ergonomic option for household cleaning. Its groundbreaking shape sets it apart from traditional sponges on the market. We recommend rinsing it thoroughly under water before first use and after each use. It is recommended to replace the sponge every two months approximately. Perform a test on a sample or in an inconspicuous area before using it on delicate surfaces. Spontex Gratt & Flex sponges are machine washable or dishwasher safe at 40 °C. They are resistant to diluted bleach. The absorbent part of the sponge is made from cellulose derived from ecologically managed forests. Made in France.
