These all-in-one dishwasher tablets are packed with natural ingredients and are 100% plastic-free, palm oil-free and vegan. Like all Marcel's Green Soap products, they contain no colourants, parabens, phosphates, chlorine, ammonia or acids. They are at least 97% biodegradable. The tablets are wrapped in a water-soluble film, so there’s no plastic to remove. The film is made from corn starch and dissolves completely during the wash - leaving no plastic residue in your dishwasher or the water system.
