The other day I had pencil marks on some VCT tile and when I went to mop them up they really gave me a time getting them off. So the next night I had the same thing and this time I just took an eraser (duh) and erased them.
That is a classic case of KISS. (Keep It Simple Stupid). The lesson I learned here is not to overthink a cleaning problem. As a professional cleaner I have multiple options for various cleaning situations. Sometimes that is a good thing but sometimes it can be a hindrance also.
So the moral of the story here is not to overthink a situation. Whether it be a cleaning problem or some everyday occurrence.
Hope this helps.
