Got 2 spray bottles - one has just plain water as marked. I use this to spray water and then wipe with a tissue or towel.. this way you don't need to soak the towel and get mushy and wet. Its quicker and cleaner.
The other one contains vinegar + water = disinfecting counter tops. Also for the sink. Just use the spray bottle to spray and wipe away clean!
In addition to this I use baking soda for the sink.
What is your tip to chemical free cleaning??
