I've been using Ecover's Lemon and Aloe Vera Dish Liquid for months now and just love it.
Ever since I started using environmentally friendly cleaning products, I've realized just how strongly scented most chemical cleaners really are. This subtly scented dishwashing liquid gets rid of the most stubborn cooked-on food and leaves all of my dishes sparkling clean -- all thanks to plant-based ingredients that are fully biodegradable and suitable for septic tanks.
To top it all off, there are no phosphates and both the bottle and cap are recyclable!
Price: from $3.99 to $5.95
