Bottling bucket: I normally make 10L batches in a 3 gallon carboy, so my bottling bucket is often my 18L brew kettle. I scrub it between boils, and soak it in sanitizer for at least 10 minutes before bottling. I have a feeling that this might be the culprit. I've since picked up a dedicated bottling bucket.
Hosing: throughly rinsed with hot water between uses. I soak the tubing in PBW for ~10 minutes before bottling, rinse thoroughly with hot water, and sanitize before use
Caps: as is, soaked in sanitizer for at least 10 minutes before bottling
