A. Hi K.Rajendra,
Your question seems a bit vague, but organic contamination is probably the most common cause of brittle deposits. You might run a Hull Cell to get a better feel for the situation, and possibly a StressTab, then carbon treat to remove the contamination. Good luck.
Luck & Regards,

Thank you very much for the suggestion.
