Sometimes the cap on your Z Clear Paste doesn’t get closed all the way tight. This can cause the product to dry out but can be fixed by following these steps.Start by putting a few drops of water into your Z Clear Paste solution. Microwave your Z Clear Paste without the lid for no longer than 5-10 seconds. Be extremely careful not to over do it; only microwaving enough to bring the Paste back into a liquid state. When the Paste is brought back to its liquid state, put the lid back on and shake it.Lastly, store the Paste at room temperature to cool back off and turn back into its original solid state.
