Why Buy Industrial Solvents To Clean A Pan?

Store bought cleaners are unnecessarily harsh-designed to handle 'tough dirt and grease' in hard water conditions. Sorry, but how often are you dealing with that, unless your a mechanic? If you routinely maintain your home, it isn't contaminated with 'tough dirt and grease,' only the occasional cooking pan is. And that only if you allow it to dry and harden on. At me mum's for Mother's Day yesterday she grilled shish kabob in a broiler pan. The moisture from the veggies and marinating sauce really baked onto the pan. We simply soaked it in the sink with vinegar and baking soda while we ate. After the meal, even that pan was pretty easy to clean without resorting to industrial solvents to do it!
Fact is, most homes can be very effectively cleaned with mild cleaners. There are countries where cleaning 'supplies' aren't a $2 billion dollar a year industry. We are misinformed when told third world societies are 'backwards.' What does that really mean, anyway? Are 'forwards' countries like America better? Ones that are destroying life with their excessive manufacturing of things with the purpose only being to sell more stuff? C Anne
