How to clean tile or marble countertops ?
One cup of 12% hydrogen peroxide and a few drops of ammonia in a spray bottle,
Be sure to work in a well-ventilated space (employ the exhaust fan over your stove or open the windows), and wear gloves and eye goggles. Spray this mixture onto the stain, let sit for a minute or two, then wipe clean with a towel or chamois. Repeat until the stain disappears, then rinse well with water and dry with a clean towel. （I always use fiber wash cloth)
如何清洁瓷砖和大理石台面？
将240 毫升12%的双氧水置于喷壶里，再加上几滴阿摩尼亞 （氨水）。
注意通风，带上手套和眼罩。在脏处喷洒，等1-2分钟后用布擦去，重复几次直到表面干净。然后用清水再洗擦干净。（我一般用纤维抹布）
