I do not think the actual products have changed at all, Nick, although I could be wrong.
We tried it. Dad’s verdict (and he didn’t know it had been put on at 30ºC): “There aren’t very clean.” I didn’t even speak to him or give off any signs! LOL
Admittedly, 30ºC is not exactly freezing – it is classed as “cold”, though – but only some fashionable items and fashion sportswear need be washed at 30ºC. However, I doubt many know this, and I also doubt how one is meant to remove some dirt and stains at 30ºC.
Engineering I’ve spoken to have said that some heat (over 40ºC) is needed sometimes. I am all in favour of saving energy, but there can be a case when saving energy likes to goes too far.
Also, someone here mentioned that it is not right to simply improve detergents, polluting our watercourses, and turning the temperature down. We get our electricity from Ecotricity, which generates green energy. Admittedly, the energy we get is still the same as before, but we are instead paying a company to generate new sources of green energy, not simply carrying on using the same green energy sources that have been around for years. It’s not a con – honest!
For us, it’s this:
Daily loads (i.e. colours): 40ºC Minimum Iron (with Persil Gel Colour tablets)
Bed linen: 60ºC Cottons (with Persil Gel Colour tablets)
Towels: 60ºC Cottons (with Persil Gel Colour tablets)
Some ‘special’ fashionable items: 30ºC Minimum Iron (with Persil Gel Colour tablets)
Dishcloths and E-cloths: 75ºC or 95ºC Cottons (with Persil Gel Biological tablets)
Yes, I do a monthly maintenance wash with biological powder/tablets: 95ºC Cottons programme.
Now, where was I? I’ve lost track of what I was saying… LOL ;-)
