General rules for rubber
Rubber is non porous but not inert, which is the distinction that matters.
A milk mark washes off with warm soapy water. What causes lasting harm is what people reach for afterwards: bleach, solvent and oil based products all attack rubber, and the effect appears gradually as hardening, cracking or a permanently tacky surface.
Check the underside of a rubber mat as well. Water trapped under one against a floor is a separate problem.
Check the label
Rubber is degraded by solvents, by oils and by chlorine bleach, all of which make it harden, crack or go tacky over time. Warm soapy water is the correct clean, and the damage from a strong product shows up weeks later rather than immediately.

Rubber in a house is natural rubber, EPDM or a synthetic elastomer, in mats, seals, toys and flooring.
It washes easily
Nothing absorbs, so detergent and warm water remove a milk mark completely.
It degrades chemically
Chlorine bleach, solvents and petroleum based products attack rubber. The result is hardening, surface cracking or a tacky bloom, and it develops over weeks rather than immediately, so the connection is easy to miss.
Heat is bad for it too
Rubber perishes faster with heat, and heat sets the milk protein at the same time.
Mats trap water underneath
A rubber mat on a hard floor holds moisture against the surface below it, which marks wood, stains stone and starts a smell.
