It depends what you are trying to achieve with your natural products. I'm asthmatic and I can't tolerate many of the sprays or strong smelling products that fall under the 'natural' heading.
So for me a natural clean is a bit boring compared to people who have delicious sounding cleaning recipes that I'm quite envious of, truth be told.
But, I can keep the house just as clean with much more boring methods like damp dusting rather than using polish, anything with a build up of grease just gets tackled with hot soapy water (ecover) and anything limescale-y gets vinegar (which thankfully doesn't make me wheeze) The oven is my nemesis, hot soapy water again but I use a ceramic scraper. I have a steamer for keeping the bathrooms clean and other tougher jobs around the house. It all requires a lot more elbow grease - it's a pita but it gets the job done.
