Hi Cherokee,
Bkf is great for cleaning innsulators.
just leave them soak,until they sparkle.
bottles are a differant story
soaking in bkf just does not cut it.
welcome to the forum !!!
Soaking in BKF will do okay, but if there are some stains on your bottle, even acl, BKF will get it off by scrubbing. I have some Hartman Beverages bottles that looked hopeless with staining, but after scrubbing them really well with BKF they looked mint.
