I do agree with the aluminium thing though, Scooby. Our pot and pans now are stainless steel. It is tough to get pans without teflon these days (which supposedly is also aluminium). I have heard (but havent bothered to research it so dont quote me) that aluminium is strongly linked to Alzeimers.
Definitely best to go as natural as you can. Thats why we only use natural cleaning products and only when really needed etc.
