One of the challenges of sustainability that we will have to face sooner rather than later relates to cleaning products. Industrial cleaning products are effective, but often highly polluting. We need to find a balance that allows them to be used in a way that takes their environmental impact into account. Residues of many cleaning products are toxic and end up in water, air and soil. An alternative available to everyone is to use homemade, eco-friendly cleaning products, using items that we usually have at home, such as lemon, vinegar, bicarbonate, alcohol, aloe… which, when properly combined, perfectly fulfil the disinfectant and cleaning role we are looking for. A clear example would be homemade hydroalcoholic gel to combat the pandemic. There are a number of tutorials on how to make them easily and safely on the internet.
