Our son has eczema, so we're constantly searching for the best products that won't irritate his skin. I love the smell of laundry detergent, but typically we have to choose unscented products because the chemical scents cause skin irritations and rashes on his body. We love Zum laundry soaps because they don't seem to bother anyone's skin yet leave the clothes clean and great-smelling. I first ordered the Zum Patchouli-Frankincense detergent that comes in the smaller, 32-ounce size. I love the smell of both detergents, but I prefer the bigger, 64-oz size because the lid is easier to pour into and the bottle lasts longer. At times, I use a little more than the product suggests and it doesn't seem to leave a detergent stain like other detergents can do in my washing machine. I do feel like this detergent doesn't require as much fabric softener (maybe due to the essential oils?), but I do throw a fragrance-free sheet in my dryer to eliminate the static that is a problem in winter months. I'll continue to buy this product religiously!
