No Tox Life® CASA AGAVE® dish brushes are easy replacements for plastic dish brushes and sponges in the kitchen and home. This removable-head dish brush has an uncoated wood handle and brush head, with agave fiber plant bristles. It is ideal for general dish washing. Nonstick pan safe as these natural bristles get soft when wet. It is held together with silver metal wire, and includes a small wire loop at the end for hanging dry. Longevity: Each brush can be used for 1-6 months. Cracking is normal and can be reduced by oiling the uncoated wood with mineral oil. Leave the brush in a dry spot after use to reduce cracking. Replace the brush head when it wears out. The handle and bristles are biodegradable but contain metal staples, so if you do compost it you will need to fish out the metal staples later from your compost. We suggest burying it in a spot in the garden so it can break down, which will take some time. Sustainability: For the wood handle, we do not use the species Teak that is endangered. White Teakwood is a different species that is very fast-growing (similar to bamboo) and even considered a weed in some countries because it grows so fast.
