I use a white plastic (3Ltr?) food grade bucket, bought some filter papers from local agri supplies I think it was about £8 per 100, make a cone shape into the top of a wide neck jar, (or jug if jars are in use), strain, jar put into cold water to chill, then into fridge. because I only have up to about 2 litres of milk for ourselves I wash the filters and re-use for a few days. bucket and jars are washed in hot soapy water, stick my nose in everyday to check smell, leave upside down to drain.
The wide neck jar I can get my hand in to wash out thoroughly.
