Need help finding a wool carpet cleaning product. Having trouble finding a brand. My research shows it needs to be pH neutral [or close to it], should NOT leave a sticky residue, and NOT contain any bleach or dye. I have found one product [Orbit ph Neutral Wool Carpet Cleaner] - but it is from the UK and can only be ordered from there. Would like to find domestic manufacturer of a like product or domestic distributer for Orbit. Any help appreciated !!!
