My kitchen is just the right size when the whole family is here for dinner, but way too big when it comes time to clean the floor. It takes at least a half hour to do a credible job. When we got the vinyl replaced several years ago, I washed it religiously a couple of times a week. Soon the frequency decreased to once a week, and then less even less often.
Needless to say, the floor no longer looks pristine. In addition to the normal wear-and-tear, there's dirt embedded in the texture of the vinyl. Although I've tried several different types of cleansers, mopping no longer gets all the dirt up. In an effort to try to improve the way my floor looked today I got down and scrubbed the kitchen floor on my hands and knees.
Actually, I only scrubbed part of the floor. Sad to say, even though I used a lot of elbow grease and tried a scrub brush, a dish scrubby, and a toothbrush, nothing I used made a whole lot of difference. I gave up and went back to using the mop to do a once-over to get the big dirt off the floor.
