We have a baby bjorn carrier which we LOVE. Instructions say to wipe clean only. Its fetid. Its beyond fetid. Its been sicked on and gummed more times than I can remember. A wipe or rinse under the sink aint going to cut it!! Will it fall apart if we stick it in the washer? Can I soak it in bleach? How the devil do you get them really clean??? Would be nice to have it spotless for DC2 but dont want to shrink or otherwise spoil it as they are pricey to replace.
