Yes!
Repeated use of petroleum-based creams and ointments can render a nappy, especially one made of synthetic fibres, completely moisture-repellant even when it appears to be sparklingly clean.
The only successful method for stripping a waterproofed nappy I've found, is to scrub washing-up liquid into the lining (best done wearing washing-up gloves) until it's turned pale green (in the case of a white nappy) all over. Then leave it overnight, run it through a couple of hot washes and rinse it an awful lot of times until there are no bubbles in the rinsing water.
It really works but it isn't something you want to do very often because it takes ages to work the washing-up liquid into the nappy and even longer to wash and rinse every trace of it out.
