Wala naman. Every diaper change gumagamit ako cotton and water sa end part tpos i let it dry forst bago maglagay new nappy. Pag minsan hndi nako naglalagay diaper muna usually pag mainit panahon, pag nagwiwi same routine, wipe with water and cotton, air dry then palit nalang ulit ng salawal. Para hndi laging in contact sa diaper.
