Not targeting you Stella, by any means. My aim is to raise awareness that homemade chemistry is still chemistry, with consequences. I imagine many people have absolutely no idea (nor do they care) how potentially liberal application of uncontrolled homemade concoctions can damage the environment.
I just watched a YouTube video of an American woman doing this at home with washing up liquid, and claiming it to be eco-friendly. What people forget is that the commercial cleaning products that they buy in supermarkets aren’t pure, they are literally a cocktail of chemicals, all finely balanced to produce a product with desired characteristics (from a marketing/technical/commercial perspective). Those chemicals include components such as antibacterials, e.g. triclosan, or benzylalkonium derivatives, as everyone seems to be paranoid about catching “germs” from surfaces (or at least they are made to feel that way by marketing campaigns). Using products like those in sprays, on top of the excess use we make of them in the home, can only increase the chemical load on the environment. I’m no eco-warrior by any means (having used 2,4-D when it was still available and some other unsavoury herbicides), but I do kind of take issue with this whole “homemade eco-culture” thing, where there are no trials to prove either efficacy or undesired impact on the environment.
