After applying PVA I found in some places happened that.
Is that need cleaning again?
For.me it look like PVA not sticking there.

Yeh it's contaminated by the wax residue. Could be cleaner, but it's really very difficult to clean properly around the wax.

This is why it's best to spray PVA. You can apply the first few coats as 'dust' coats to avoid issues like this.
