Quick Answer
If your skull turns brown after whitening, it's likely due to uneven whitening or contamination. You can try retreating the skull with a diluted bleach solution or re-whitening with a different method. However, be cautious not to over-whiten, as this can damage the skull.
Identifying the Cause
Before taking corrective action, it’s essential to determine why the skull turned brown. Check for any signs of uneven whitening, such as darker or lighter spots. If the brown color is due to contamination, inspect the skull for any debris or residue. If you’re unsure, consult a professional taxidermist or expert in European mounts.
Correcting the Issue
To correct the issue, you can try retreating the skull with a diluted bleach solution. Mix 1 part bleach with 3 parts water and apply it to the affected areas. However, be cautious not to over-whiten, as this can damage the skull. Apply the solution for 10-15 minutes, then rinse thoroughly with water. If the brown color persists, you can try re-whitening with a different method, such as using a specialized whitening solution or applying a whitening gel.
Preventing Future Issues
To prevent future issues, make sure to follow proper whitening techniques and use the right equipment. Wear protective gloves and eyewear when whitening the skull, and work in a well-ventilated area. Also, be sure to clean and dry the skull thoroughly before whitening to prevent contamination. This will help ensure a smooth and even whitening process.
