we dont have any "real" anti-bac spray in the house (i was so excited i emptied out the bottles to put my new natural stuff in lol) i never tried Ecover things as they werre quite expensive, and most of these things are so cheap!
for general purpose anti-bac spray i fill a bottle with cold, boiled water, add 1 tsp soda biccarb and about 10 drops tea tree oil (lavender is good too) and 1tsp liquid soap/washing up liquid. put in a spray bottle
also i have a general purpose cleaner i made by boiling a few soapnuts and adding lemon oil to (smalls lovely!)
to clear sinks and drains - put 2tbsp soda bicarb, and 2tbsp salt in the drain. pour 1/2 cup vinegar in and let it bubble and leave for 30mins before rinsing with boiling water
to clean floors - anything really...liquid soap or shampoo, washing up liquid...but if you prefer something more natural then add 1/2 cup vinegar to thw water (a bit smelly but it goes quickly) if you are really stuck you can use some cold water-steriliser but thats not really "green" (i just have 2 bottles of it languishing in the cupbaord!)
to make washing up liquid go farther, add a tsp of washing soda crystals too the water
use vinegar instead of fabric conditioner - and your clothes wont smell like vinegar! or 1/2 cup water with few drops essential oil (not orange, it stains)
i also make laundry gloop too which washes most things well but havent tried it on any violently dirty clothes yet!
there are websites you can buy things like soda bicarb, vinegar etc in bulk and have it all delivered, although i havent tried them. i just add a bottle of vinegar and tub bicarb soda in my weekly shop and i havent run out. even if you do its no big deal - theres nothing wrong with soap and water for all your cleaning. not that cleaning is something i do often...."oh, we have nothing to clean the floor with...oh well, il leave it for another day

" lol, great excuse to not have to do it
