Hi ! Look for a carpet cleaner called Folex . I found it at home depot for about $6 for a large spray bottle . This works on upholstery , too ! And can be used in a carpet cleaning machine, as well . This stuff is great and gets out all stains !!! Ink , wine , dust , make up , even old stains . Good luck !
I would just use soap and water maybe some clothes soap and a scrub brush keep in mind that the sun fades them realy bad
