I have a large number of 8cm square plastic pots and would like a
suitable brush for ease of cleaning. All the ones I have found are too
big and very stiff, suitable for ceramic pots. Any ideas please?

I would suggest an "old fashioned" domestic scrubbing brush, or
alternatively soak then for a while in warm soapy water then
clean with aold cloths/rags/shirts or whatever!
