I asked the Prophet ﷺ about the blood of menstruation on the clothe. He said: Erase it off with a piece of wood and then wash it away with water and the leaves of the lote-tree. (Using translation from Abū Dāʾūd 363)
سَمِعْتُ أُمَّ قَيْسٍ بِنْتَ مِحْصَنٍ تَقُولُ سَأَلْتُ النَّبِيَّ ﷺ عَنْ دَمِ الْحَيْضِ يَكُونُ فِي الثَّوْبِ قَالَ حُكِّيهِ بِضِلَعٍ وَاغْسِلِيهِ بِمَاءٍ وَسِدْرٍ
