'add water' laundry liquid 250ml. Biological .
Get the bottle concentrate and squeeze. Get 10ml of concentrate into the left hand side measure or level guide there.
This small amount can then be tipped into the clothes wash machine.
This can be for a front load or a top load type clothes washer.
Indeed, you can add some to water to soak for a long time too.
I soaked a woollen panda bear picture round bit of sheepskin from out of a dusty space and after three days you could see lots of work on it. After that, a further wash in the washing machine with another 10mls and it came up perfectly.
Used in your daily normal laundry you may notice colours more than with the usual laundry cleaners. Sometimes I add a little to my wife's wash where she has also put usual laundry detergent already.
