I have just got a new washing machine and am going to turn over a new leaf in sorting washing and using the right cycle. No more stick-it-all-on-at-40-regardless here!
The machine instructions say its best to have two detergents, a bleach containing one for whites (which will also help keep the machine clean) and a special detergent for colours.
Then they go and recommend Simply eco-friendly washing tabs. I would love to use these. But it's not clear to me which of the Simply products is a bleaching one or a for-coloureds one. They just have bio and non-bio.
Oh take no notice to them recommending Simply eco-friendly, just a big PR spin.
I use Ariel on a 30 or 40 degree wash for my whites with a scoop of Vanish to get rid of stains and do my coloureds/darks on a 30 degree wash with a non-bio. Using a lower temperature the majority of the time will do more for the environment (electricity and water) than using an eco-friendly detergent.
I am very cynical and will say that: they recommend something that they will make money on, prob get paid to recommend it. Washing tablets are a very expensive way to do your laundry. Bio contains enzymes to clean your washing, non bio often contains bleach to get things cleaner. Me I would just use sainsburys own bio or non bio its really cheap and I am very impressed with the wash I get in my bosch machine.
If you buy 4 30-tab tubs online (£2.99 each), with a free tub of dishwasher detergent thrown in (£4.99), they work out at £1.74 per tub or 11.6p per wash (& that's if you use 2 tabs, you can often get by with 1)
They are good value, & they wash well, & they are green
The Pure ones are prob best for coloureds (they are a bit more expensive though) & the bio for whites if you have no sensitivity issues.
With no d/w, your best deal price-wise from the website would be the double-tub boxes - £5.79 each & you get 4 for the price of 3. But last time there was a Simply thread a few people said you can buy single tubs in some supermarkets & they have a 50p coupon inside. (Oh - and apparently Farmfoods sell it for £1.80 a tub )
