My Dow Scrubbing Bubbles for the bathroom. I know they are chemicals but the bathroom is so clean and sparkly when it's done. Just spray and wait a few seconds and wipe off. It cuts soap scum easily and cleans real good.
I also have a homemade solution around the kitchen I just couldn't live without. It is made of vinegar, washing soda, borax, and a dab of dishwashing liquid, and water. It cuts grease like there's no tomorrow and I use it on the kitchen counters, stove top, and microwave.
