Not specifically for bike use but one that’s big enough to fit a cassette in would be great (most seem too small being aimed at jewellery etc) – any recommendations for a budget, occasional use but reasonable cleaner available on the web?

You just missed one in Aldi. £20 two weeks ago. Bought one for my wifes necklace and rings.
[certainly not for my bike chain, so sirreee that would never fit in there with warm water and vinegar…never. What you mean put dirty bike bits in where your jewels go…what kind of bike fiend do you take me for!!!!?]
