好煩惱!!!雲石問題...@@

這是因狗尿內之uric acid , 因是酸已etch your marble which is alkaline(Calcium carbonate) . Marble是鹼性已受蝕而變黃 . 點去除黃漬是其次 , How to prevent you pet to restain again is the most important thing to do !!!否則 it is waste my time to teach you how to clean .

將己黃云石抹干後 , 用布索有火酒蓋在有漬處 , 用火酒抽出己滲入石內之色 , 等一會抹干 , 再用鹼姓detergent 再擦抹一會 , 過水後抹干 , 如還有色在 , 重復以上工作 . If you donot have any good alkaline cleaner , go to www.wellconnected.com.hk , looking for APSD-01 for stain remover . Since your marble particular the urinated area ,will lose its gloss & get rough , you need to coat a finish to restore its beauty , same website find the floor finish FF-01 with detail information . Hope can help !!

Sorry to use English not because my Enblish is better but my Chinese writing machine will take me hours to finish the answer .

你試試倒些漂白水在雲石面，過2-3分鐘用清水抹淨，如有效果就繼續努力(漂白水不用稀釋)。
