Eucalan provides superb cleaning and conditioning for any fiber!
Why shouldn't you rinse when you use Eucalan?
Firstly - convenience and the environment. Not rinsing saves two precious things - time and water! Eucalan is also low sudsing and it's better for wool to be handled as little as possible while wet because it prevents both matting and shrinking. Also, not rinsing helps the fabric to retain scents such as lavender or eucalyptus that helps to prevent moths from staying in the fabric.
