I only clean my wooden floors with hot water. There's no need for any additives, though it is sensible to use an antimicrobial, like vinegar, around toilets. Remember, it is normal and beneficial to have bacteria in our homes if managed well.
For basins, showers and baths I use a home-made cream cleanser, the ingredients of which I can buy in bulk, free of plastic packaging:
Mix several teaspoons of baking soda with a good dollop of eco dish washing liquid. Stir to make a paste. Simple!
Is perfect for areas where we typically use antibacterial products. Vinegar has antimicrobial and antioxidising properties. Its acidic nature allows it to break down sticky residues, and mineral deposits like lime scale. I use vinegar for cleaning the toilet and disinfecting my chicken coop, and can source it in bulk.
