Do you use "white" & "coloured" laundry powder/tablets/liquid?

I use Aldi's Almat liquid for colours, but I 'doctor' it with washing soda (half a bottle of liquid to one teacup of washing soda, top up the bottle with warm water to dissolve the soda). I find this softens the water and makes an already cheap wash product even cheaper.

I only use half a capful per wash and pre-treat any stains with the mixture. (How cheapskate is that ). For whites I add a scoop of vanish oxy white or similar (Aldi do their own brand but I forget what it's called now). Since doing this I have saved a small fortune on washing products which used to either a) not work or b) bring me or the kids out in a rash.

I use Asda's own brand fabric conditioner. Cheap and effective. Stops static cling - IMO vinegar does not seem to do this. As for Ironing water - 2 drops of lavender oil in some water (shake well to mix) seems to work very well.

Have to say, have never used different powder /liquid for whites/ coloureds - just the same for both. have tried most brands over the years, but currently quite happy with Tesco Value Bio powder.
Mind, I've never been great at separating whites fromm coloureds unless they're coloureds which I think might run (very new or red). No-one's complained over the years either!

I use washballs for most ordinary darks.

Heavily soiled darks (hubbys workclothes) and whites go in with own brand non bio liquid, usually tescos and blue lenor.

Found tablets and powder left white marks on my dark washes.

Have saved a good bit with the washballs, however the balls disintegrated so use old tights instead!

I just use a small measure of normal (Costco own brand) washing powder mixed with washing soda (half & half) and don't notice any excessive fading of colours. I don't use fabric conditioner either, thanks to my old style advisors.
My mum is obsessive about using the Ariel Colour for coloureds and and Ariel 'ordinary' for whites, and fabric conditioner, and thinks it does make a difference. However, today she gave me a pile of towels, which she has now spurned because 'they've faded'. (Not really sure what's happened to her - she used to be sooo old style!).
There is actually nothing wrong with the towels, and they will go beautifully with my new shower room (to be installed 26th May, can't flippin wait :j).

I use one persil colour tablet for coloureds, tesco value powder for towels and cleaning cloths and currently M&S whites liquid for my white bedding (only because it was 2 for 1). I always add a scoop of soda crystals and sometimes use a drop of fabric conditioner but usually white vinegar.

I have recently been wondering though whether to switch down to tescos own colour tabs but as I've only got through less than 2 48 boxes of persil in over a year the saving would be minimal.
