Hot spots are basically due to focused light from your flash. Best way to remove is diffusion. Also, what happens is your camera is metering your light based on the surface of the bottle. Once your light hits, the hotspot is an overexposed area.
There are a couple things:
1. Are you using the built-in flash?
2. If not, which flash unit are you using?
Right now it sounds like you're taking pictures of bottles. Regardless, of the light diffusion, you will get nice little reflections.
Here are a few things I can suggest:
Opt1:
Build or buy a "box" that you can basically put your product in. This box is made of cloth. If you've seen those laundry hampers that collapse, and how they're made of cloth, it's something similar to that. Shooting through the front hole, and with a lot of regular desk lamps on top and on the sides (experiment) you will totally get rid of hot spots while lighting your item very evenly. The trick here is EVEN lighting, so that your camera will meter correctly. No need for flashes here. You can be creative, make a box out of pvc or something, wrap it with a white table cloth, get a few desklamps and shine them around the item
Op2:
Use those floor lamps and have them bounce off the ceiling. You should get A LOT. This will diffuse the room and make the room a reflector, giving you again, even lighting.
Op3:
Get a tripod, turn off your flash, give the room some soft light with a few floor lamps that bounce off the ceiling, or just provide a little light somewhere that's not harsh, and do a long exposure, thus you don't need a flash.
Op4:
Get a lighting setup with huge shoot through umbrellas. You might be able to get away with 32in shoot through umbrellas. But this is an expensive route.
My recommendation:
1. No time: just turn off the flash, get a tripod or stack some books and do a longer exposure without flash and very unharsh ambient light.
2. A bit of time and creative motivation: build yourself a box out of pvc or something, and wrap tightly with cloth. Cheap desklamps, walla. Experiment with layers of cloth, what kind of desk lamps, distance of desk lamps from the product, positioning, etc. Fun =) May be a good idea to invest in a little box studio you can buy online as well.
I might have missed some details you mentioned in previous posts, so let me know if you've tried the above and need more help.
