Fun question!
I'm going to try your tub cleaner. I do think a lot of these recipes are sponsored by the company that makes Dawn, though!
Round-Up is horrible stuff anyway, but in my area, everything runs downhill and ends up in the many streams that feed our reservoir. So whatever people use on their yards, we drink. I saw weedkiller made of vinegar, Epsom salts and a little dish detergent (ratio: 1 gallon white vinegar, 2 cups Epsom and about 1/8 cup of detergent). Mix gently so you don't get all bubbles and put in a spray bottle, and spray on a windless dry day in the morning, stuff should be dead by night. I found it took until the next morning. It kills everything so don't use it on grass. It worked for dandelions and now I'm going to use it on poison ivy.
Baking soda cleans everything: toilets, sinks, counters, porcelain kitchen sinks. I shake a bunch into the toilet and stir with a regular toilet brush. For everything else, make a paste, rub the sink, then rinse - and get the drain deodorized at the same time. I don't use any toxic cleaners at all anymore, and I don't spend a small fortune on the so-called "natural" ones either.
Silly kitchen hacks we use are:
- wash fruit, let it drain in the dishwasher rack pulled out. It gives a lot of extra counter space!
- instead of the typical bowl of olive oil & herb marinade to brush on roasted or grilled veggies, use a tall drinking glass. Put the herbs, salt/pepper in first, then oil, then stand the basting brush up in the glass and it won't keep falling all over the stove or grill, and it won't take up the space that a brush does lying down. The glass cleans easily in the dishwasher.
-a new toothbrush is great for cleaning the stringy silk out of corn on the cob. An old toothbrush is great for cleaning around faucets or in tile grout.
I saw a photo on line somewhere of people using a plastic laundry basket in the bathtub, as a little "cage" for their toddler. There's room for a 1-2 year old, the water flows in through the holes in the sides, the toys don't float away, and the sides help support the child, it rinses well and dries upside down in the tub and goes back in the closet.
