Meguiar's Ultimate Paste Wax Eats Pad?

I was sorting out and cleaning up some of my junk and happened to stumble upon some old Meguiar's hand applicator pads. Remember the time when I did a sealants comparison? I used a different applicator pad for each product. After used, I washed them with dish detergent, dried, and kept them.

See what I found below. Okay, just ignore my wrong hand writing. It should be Meguiar's Ultimate Paste Wax.
The pad just crumbled when I held it.

The rear side that did not come into direct contact with the Ultimate Paste Wax seems to fare better.

The other pads that were kept in the same box are still in good condition.

The pad for Finish Kare has some discolouration but still feels good and soft.

The Autoglym Extra Gloss Protection applicator pad has the least discolouration and the pad for Fusso is still in good condition.

All the pads were brand new when they were used for the test to ensure an unbiased result. After the test, I chucked them away and forgot about them. Too much junk, haha.
I am not sure if this is pure coincidence or are the chemicals in Meguiar's Ultimate Paste Wax a little harsh to applicator pads.

If you have any experience regarding this, please share them.

That's it for this post.
Happy detailing.
