Do they leave any powder or residue behind?

No, they don't. They are similar to the silica packets that come in the new camera or electronic packages. With the exception that these can be reused and the silica packages can not. The other difference is that these are cut and shaped to fit inside your camera housing. You may find some powder residue left on the surface of the plate you use in the oven to restore the inserts.

No powder or residue is left behind. They come in a heavy zip lock bag and that's what I keep them in until I use them.

Considering that the material seems to be made of a fibrous or paper substance it does seem to deteriorate depending on how much it is handled. I try to use only one insert in my go pro when diving and it seems to work fine. I try to handle the desiccant pad very gently. Another tip is, if you are staying in an air conditioned place an then going out for a dive in a warm climate, you should consider acclimating your gopro to the temperature out side in advance to using it. Say 1 hour if possible exposure to climatize the camera and case. This will make it less likely to fog. As far as powder residue inside the case. If that occurs A q-tip slightly moistened will clean the residue out followed by a dry q-tip. I also keep my inserts in a zip lock bag to protect them. Careful handling of the inserts and they will last a long time. Good luck, hope this answer helps.

Yes. The product is clear and doesn't leave a color residue like some powder formulas.

They should come off cleanly. I had no sticky residue. If it does wipe it with some lacquer thinner.

Mine were fine, but you can try wiping them or after a while the powder will go away.I don't think you have anything to worry about.

I haven't removed mine, but it doesn't seem as though it would be hard to remove or there would be any residue left.

I followed the directions and used perhaps a flat 1/4 teaspoon for a small cup. After stirring, there was no appreciable residue, so I doubt if there were any fillers.

The manufacturer has described them as powder coated. Please let me know if there is anything else i can do for you or if you have any questions.Sincerely,Shannon

No, I haven't noticed any metallic residues. I have used my grinder attachment many times since purchasing it.

I just bought these recently & I have seen no residue. I seen those reviews as well so not sure why some have the residue. I've used both cold/hot water from the sink, no residue.

We followed the instructions and practically we forgot about them. I believe they dissolve with watering and with the rain. We did it last 2013 fall, so we have not seen anything different yet. I just bought another box.

In my opinion, yes.The product is a spray and dries to a powder. You will need to wipe that off with a fine hair type of brush to remove the residue.

I have had no contact with any black residue. I have seen nothing of that sort on these shot glasses. I also made cookie shot glasses with these and used them in an oven with no issues. Washing them in the sink has caused no issues either.

I have had them installed for a couple of months and no black residue so far. There was actually black residue on the old brass hinges, but I think it was due to whatever lubricant the previous owner used.
