One of those chemicals is called 2 butoxyethanol, which is present in most commercial cleaning products, in quantities too small to be listed on the labels. However even at those concentrations it has been shown to be absorbed easily through the skin both from contact and vapors. It is carcinogenic, it affects the kidneys and reproductive health (and if female reproductive health isn't visual enough think "testicular atrophy"). Have I convinced you? DIY!
Some people swear by using a solution of 50/50 water and vinegar for just about everything. Not only am I not too fond of the smell, but I don't think it works very well either. I tested various recipes I found on the web and finally came up with my own. The first one is great at dissolving grease and is perfectly safe to use on food preparation surfaces: the alcohol evaporates and the only other inedible ingredient it contains is soap, but there is so little of it the spray can be used without the need to rinse. The second can be used to clean your oven (without killing your braincells or endangering your unborn child) AND your toilet. I like using the glass cleaner for ceramic sinks as well as glass and mirrors. The dishwasher detergent can also be used as a scrubbing powder with bleaching power (and without the harmful vapors). Finally the spray for your shower curtains can double as a fruit and vegetable cleaner.
I mentioned this is cheap and it is: however buying all the ingredients the first time you make these will cost more than a single spray bottle of all purpose cleaner. This will be a considerable long term savings, as you can make many many batches with your supplies.
One last word of caution: always label the bottles properly and include a list of the ingredients. These are perfectly safe to use as directed, and they're definitely less toxic than most commercial cleaners but in case of accidental ingestion you still need to be able to tell the poison control center what the product contains. It's a lot easier to check the bottle rather than look up this instructable while your kid is vomiting and 911 is on the line....
