There are always the prospect of corners being cut (like in the type of "Velcro-like" Hook&Loop systems used);
and, though the adhesives and even the foam, itself, used for buffing pads has seen improvements over the years:
I always preferred to follow the recommendation to not wash pads
that was once promulgated by companies such as Meguiar's.
These un-washed, (yet still cleaned), pads': Foam, Velcro, and Adhesive components...
tended to last longer, IMO; and with seldom, if any, mention of:
"separation/delamination and or deterioration".
But to keep up with Customers' interest/(IMO: also market share) in:
Washing pads to clean them (instead of non-wetting methods);
and: For better and/or For worse:
Along came the "washable" Soft Buff 2.0, and the "washable" WXX07 series.
I also think about:
Without incorporating a detergent/water washing method for buffing pads...
What would have been the fate for the high-dollar mechanical pad washers?
Anyway:
Hope your pads have not undergone any undue soaking stress factors.
