Dish Detergent is Magic

In the bathroom. A soapy bucket of water with an ample amount of dish soap in it (and a scrub brush, brillo sponge) will clean soap scum way more thoroughly and with much less the effort of most any "bathroom/shower" cleaner on the market. I wasted my money on the toxic blends for a few years before discovering this simple solution myself. It's Soo much more effective. I use it on showers, sinks, toilets. If I want a surface disinfected then I'll use something else to do it, like Lysol, but for cleaning, especially soap residue and mold, stains, the dish soap wins out every time.
