Remimix Remimix Powder by Hatchwell for minor wounds and scratches. This medicinal powder quickly stops bleeding, which may occur during grooming. An essential first aid product for any professional or pet groomer. Suitable for all animals. 30 grams. How can I prevent Remimix from clumping? Clumping is unfortunately a common issue with astringent powder products and cannot be prevented, but we can recommend some tips to keep your product lasting longer. Avoid storing the product in the same room where you bathe if possible. Pet salons can become very humid places to work in, and astringent powder is very sensitive to moisture in the air. Do not leave the container open longer than necessary, and ensure it is tightly sealed. Try placing a small bag of "silica gel" with your powder (the type you find in a new bag) as this material absorbs moisture and can help keep your powder dry.
