Here is a link on the dangers of common household cleansers. Here and here are some links on the dangers of laundry detergent and fabric softener. I have a feeling that this post will be long enough without me trying to list the danger of each thing you are replacing.
Depending on how dirty your sink and tub are you can either use vinegar/water and a cloth, baking soda and vinegar scrub or the Pumie. I have also read that Bar Keepers Friend is pretty Earth friendly.
For cleaning the counter top I use vinegar and water. For cleaning the stove top (when it is all gunky and crusty from food), I use baking soda and vinegar. I let it sit and it just wipes off with very little to no scrubbing.
So as you can see, it doesn't have to be complicated or expensive to clean your home the green way, with green and natural cleaning products.
