Eco friendly recommendations

It looks like people are going back to a time before high pressure advertising, where everything from yesterday was poor and anything new was better, when any of my family have a cut or similar and I am asked how they can treat it, after telling me the problem, their first remark is how can I treat it and don't say use vinigar, if I have a cut jor graze the first thing I do is wash it with vinigar and so far I have had no problems after that, as for using it for cleaning, I have 20lts. of vinigar so must see if I can sell it to OH
