As we use up our store-bought bathroom and kitchen cleaners, we are replacing them with solutions made from natural ingredients that most households would have on-hand anyway, such as lemons, vinegar and baking soda. We simply re-use the spray bottles once empty, diverting them from the landfill or from being down-cycled. I found a great resource here for recipes: http://blisstree.com/live/25-safe-non-toxic-homemade-cleaning-supplies/.
We've also invested in a good old-fashioned toilet brush (we used to use the wands with the disposable cleaning heads). The hubby's old t-shirts and our old socks will replace the disposable swiffer dusters for cleaning furniture. Shamefully, we've used many a paper towel to clean glass and windows. I remember using old newspapers on the windows and glass, which did a pretty good job.
Little momma and the big guy haven't really had to help to the major cleaning; they are only responsible for picking up after themselves. Now's a good time to introduce housecleaning chores to them and explain why we're switching to homemade cleaning solutions.
