Nikwax avoids materials in its cleaners like palm oil, which may be sourced from unsustainable plantations. If your animal rugs or coats are relatively new, or recently treated with Nikwax Rug Proof™, then cleaning with Nikwax Rug Wash™ will not only remove contaminants, such as dirt and residues left behind by household detergents, but also revitalise DWR.
