Une composition détergente comprend un composé à base de fluor ne contenant aucun atome de chlore et au moins un composé sélectionné entre géraniol et nérol. Dans la composition détergente, le rapport des quantités de géraniol et de nérol à la quantité de composé à base de fluor ne contenant aucun atome de chlore est de préférence compris entre 10/90 en poids et 80/20 en poids, et la quantité totale de géraniol, nérol et de composé à base de fluor est de préférence 30 % en poids ou plus. Cette composition détergente présente un effet détergent élevé, notamment lors du décapage. Lors du nettoyage, un article auquel adhère une substance salissante est nettoyé avec une composition détergente puis rincé avec une solution contenant au moins 80 % de composé à base de fluor sans atome de chlore. Cet article subit de préférence un nettoyage ultérieur avec de la vapeur, sans composé à base de fluor ne contenant pas d'atomes de chlore.
