Hi Nadia and Dani, we would recommend our Euca Glass cleaner for most spot stains on carpet of fabrics like lounge or car interior. The Glass is unique in that it cleans and will evaporate so not leaving any residue in the fibers. the problem with most carpet of fabric cleaning is you make it look clean, but residue you cannot see remains , which then over time collects dust and other minor dirt to make the stain re-appear ( called re-soiling ). its not the stain , but the cleaner you used previously .
Euca Soaker will work well, but make sure you either turn it into a paste or even better dilute to a liquid mix. before you dab on the stains , do a test clean in a hidden corner so you are sure your carpet is colour fast, rub gently and have a bucket of clean water and a different clean sponge to apply clean water to the area, do not over wet the area. a dry cloth to dab dry , recheck progress and repeat this process as needed. dont leave any cleaner on carpet for long periods or to dry. hope this helps, let us know if any other questions , regards Gavin
