Where to store washing up powder and dosage?

[Nelumbo]

I always used to use the washing up tablets, one for a half load one for a full load.
I got a new washing machine and for some reason started using liquid, I've read that this isn't the best option and powder is better.
I bought a box of washing powder and it's too big to house in my cupboard and also quite messy.
I'm sure I've seen containers but can't seem to find any now. Any ideas?

The other thing is I really don't know how much to use!
Its says 50ml for light soiling, my machine has a daily 59min wash cycle which i use the most, it's an 8kg machine but this cycle is meant to be for 3-4kg loads. I tend to put in maybe a few trousers and 4 or 5 tops, so how much powder should I use for this type of wash? 50ml seems way too much, would half be enoigh?
I also don't have a scoop to measure!

You don't have to pull your hair out about how much to use.

Half a scoop for a small load or lightly soiled clothes, Fuller scoop for heavier load or more soil.

This isn't an exact science. Nothing bad is going to happen if you put in too little or too much.

I use the small pink scoop out of a vanish stain remover tub, x2 scoops for a light wash . Then an extra scoop for a longer / hotter wash. No idea if that's right, it doesn't seem like very much powder but it does seem to be enough & work well. I add a little fabric softener too.

Hi, may I know which brand of powder comes up with the blue jug. I love it. or does it need to be ordered. Thanks a lot.
