How do you get dried hand lotion from a decorative pump bottle?
I soak it in warm water. Use a small brush to clean the tube and nozzle. You can buy a set of baby bottle brushes at the dollar store. The tiny nipple brush is usually a good size.
Warm with a hair dryer so that it "melts", then you can wipe away.
Add hot water to the bottle or soak it and the pump in a sinkful of hot water. You can use rice and a bit of water to "scour" the inside of the bottle. Then rinse well until the water runs clean.
Fill the inside with hot water and let soak. You can always add some baking soda and vinegar to the inside and coat the inside to do some magic. Then clean with a thin scrubbing brush.
If the soaking doesn't work as well as you'd like, use a bottle brush or a denture cleaning tab inside the bottle. Good luck!
