Murchison-Hume Heirloom Dish Soap is Eco-Friendly and a pleasure to use. The 100% biodegradable, plant-based formula ensures sparkling clean dishes with no soapy residue. Regular use also helps to keep your plumbing naturally clean and odor-free. Our amber PET bottles instantly elevate any kitchen design. They are highly recyclable, endlessly refillable, and chic enough to leave on the counter of the most beautifully designed kitchens. GOOD TO KNOW: Cruelty-Free Murchison-Hume products are never tested on animals. Why We Love It * PRETTY TOUGH: Our plant-based formula is safe for septic tanks, readily biodegradable, and cuts through grease better than the bubbly brands.
