Hi All
Solution uk sell Solugard I don't think anyone else does
Solugard is nanotechnology-based It coats every single fibre with an invisible UV-stable protectective layer. Water, coffee, red, wine, gravy, etc will simply pearl off the treated fibres
The best nozzle to use for this is a 500050
To use simply spray carpet lightly first with water, then spray across the carpet then up and down the length of the carpet and leave to dry, do not rub it in with carpet brush.
Hope this helps
Regards Gavin
