There is often no way to avoid some scrubbing. That's just life. If its a very small area, a Magic eraser would probably help. I am currently dealing with a home that hired a local cleaning company several years ago to clean their modestly sized home. Within 10 minutes on the first day I cleaned their home I got total evidence that this company had done a HUGELY bad job. Tile floors had not been properly cleaned in all that time, nor were the bathrooms cleaned well. OR the kitchen. They quite obviously had not bothered to move items around in order to clean behind them. The real kicker here is that they claimed it took 7-8 hours every other week to clean that house, and the owners believed them. I have never dealt with that much dust in my cleaning career, and the floors are a total mess as they only used a darn string mop and swished dirty water around. I took my steam mop there last time and even IT didn't get up all those yucky dirt lines that have settle into all the slight indentations on those floors. This kind of shoddy work really annoys me. And a house of that size does NOT need 8 hours of cleaning! That is simply outrageous.
