I have read some messages in regaurd to water spots. I have black spots which I think is mold or water underneath the linoleum bathroom floor. I use floor cleaner to clean them Armstrong floor cleaner is the one I use. I think the problem may be the shower is used at least 3 times a day and I clean the floors every day (I know, I'm a clean freak!!) There is too much water in that bathroom!! Any suggestions, what I can do to repair the stains??
