If you would like an alternative to liquid detergent<\/strong>, here is a recipe for washing powder<\/strong>, perfect for households with access to hard<\/strong> water and for washing absorbent fabrics<\/strong> (menstrual pants<\/u><\/a>diapers, washable cotton pads).<\/h3>

This article is brought to you by Odile Niederhauser, founder of <\/em>Madame Pepperpote<\/u><\/strong><\/em><\/a>.<\/strong> Based in Geneva, Madame Pepperpote helps you tidy up and organize your home, so you can stop hoarding, rediscover simple happiness and live better with less.<\/em><\/p>

Water hardness, a factor to be taken into account when cleaning<\/h3>

Water hardness<\/strong> is the expression of its calcium and magnesium content<\/strong>. It varies according to the soil it flows through, and is expressed in French degrees (\u00b0F). 1\u00b0 F is equivalent to 10 mg of calcium carbonate (limestone) per liter of water. Up to 15\u00b0 F, water is considered “soft”. Above 30\u00b0F, it becomes “very hard” (source : www.eaupotable.ch<\/u><\/a>) <\/p>

Two adjoining regions may have different levels of hardness, depending on where the water is drawn from. Take, for example, the Geneva commune of Ch\u00eane-Bougeries, where the water – which comes from the Genevois aquifer in the Arve sector – has a hardness varying between 18\u00b0 and 22\u00b0F. If you travel less than 2 kilometers, the water in the network comes from the lake and its hardness drops to 12\u00b0F…! <\/p>

When water is rich in limescale, it’s good for the taste, but not so good for the household! In fact, the harder the water, the more you have to maintain your household appliances, which can lead to limescale build<\/strong>-up. When it comes to washing, this means using a higher dose of detergent to neutralize the calcium. Or… use a homemade detergent adapted to this situation! <\/p>
