Butters - i use a small amount in place of armor all on my car dash and along the rubber seals around the windows and sunroof (this cuts down on wind noise in the vehicle - this was suggested to me by the service guy at bmw who recommended that I do this twice a year). I also mix butters with sugar to create a dry scrub for my feet, elbows and knees or I will just use them in place of lotion.
Carrier oils - I use them to dilute fragrance oils that I burn in burners around the house, this usually extends the life of the oils by about 20%. I will also use them in pre-poo treatments and add them to the water i use for pedicures and manicures to soften my cuticles.
Essential oils - I add them to my liquid incense burners and on dried flower arrangements
Shampoo - i've washed the car with cheapies, and they are really good for cleaning the oven racks and window blinds. I've also diluted them and used them to clean my makeup brushes and the sinks. Works great as body washes or for the cleaning the dog.
Conditioner - I dilute with distilled water and glycerin and use as a leave-in in the summer or i add oil and use as a pre-poo year round. If i really hate it I use it on the dog.
Silcone serums - I use it to seal the granite surround around my fireplace and bathroom counters in between normal sealing intervals (don't do this on surfaces that food is prepared upon though).
Hairspray - use as a part of a pre-treatment to keep stains in clothing from setting (doesn't work for everything but helps with stuff like ketchup and mustard).
That's about it I think, but if I remember more i'll edit this post.
Hope this helps you some.
