Among the many jobs I took to support myself as a fledging actor/yoga teacher was “natural house cleaner”. Needless to say the job was short-lived, but the skills I learned were priceless. Avoiding super processed home cleaning products is easy, definitely cheaper, as long as you are willing to put elbow grease into your weekly regime.
Mix in a spray bottle: one part white vinegar + one part distilled water + 5-15 drops eucalyptus, citrus, lemongrass, rosemary or tea tree oil.
I prefer lemon + eucalyptus for the kitchen, and tea tree + sweet orange for bathroom. Lavender & Tea Tree have potent antibacterial qualities. The white vinegar (5% acetic acid) will denatures the cell walls of bacteria and viruses (as well as most types of salmonella, but not all).
Sprinkle baking soda in sink, tub/shower and in toilet. Spray with pre-mixed cleaner & let stand for 5-10 minutes. Scrub vigorously and rinse.
Baking soda has naturally antibacterial properties and kills many germs/bacteria.
Pour baking soda + apple cider vinegar down the offending pipe, let sizzle for 10-15 minutes and repeat if necessary. Much less toxic then other options.
Spray or sprinkle seltzer water + newspaper + elbow grease for a streak free, clean reflective surface.
These are just a few that are tried and true for me. Here is another resource if you want to go deeper into the realm of natural household cleaners.
