Ah yes. The old "that's scary don't touch it, drop it" bite. I found the best way to deal with this ,at least with Albie , was to teach her the command " touch it" to show her it wasn't scary or dangerous.
I start with doing it with something she loves and when she touches it I reward while gradually introducing her most favourite treat ever (in Albies case ,sunflower seed) for this training I only used it for this and nothing else because I need her desire for the seed to be greater than her fear of an object.
Once I got her touching her safe things on command consistently, I moved on to things that wasn't scary but she didn't interact with and got her touching those and then I would throw in one scary thing.
Now I can get her to touch pretty much anything and it's almost stopped the bites.
She still doesn't like the dish washing liquid bottle ....,
