Users should ensure that the pencil tip is thoroughly dried after use by gently drying it with a tissue.
It depends! The pencil is a single patient multiple use product so you can use a single pencil to treat one animal multiple. You should be aware that one pencil contains enough silver nitrate to provide 6 treatments
Pencil tip breakage may occur if too much water or pressure is used, or the tip is not dried between uses.
The user should swirl just the very end of the pencil tip in a single droplet of water for around 20-30 seconds before use to activate the product and then transfer this droplet to the area to be treated without pressure. Do not press on the tip.
It is likely that the silver nitrate pencil tip has dissolved as it is very soluble in water. This can happen when the tip has been exposed to excessive amounts of water or not dried before replacing the cap.
