It can be if it's from an acid or similar chemical. If it's due to a rubbing action, though (like those novelty soaps with the grainy texture), it's mechanical. Also, "weathering" is an odd term to use with a living organism. It's more akin to cleaning.
Which of the following is an example of chemical weathering?
The weathering process involved in the formation of tors is exfoliation (onion skin weathering). Exfoliation can be mechanical or chemical. Mechanically, exfoliation may be a result of the different expansion rates between exterior and interior layers. Chemically, the exterior of the rock can be chemically altered to minerals of higher volume, causing it to slough off from the rock to which it was formerly attached.
Physical weathering is: frost, crystallization, exfoliation,, biological and pressure release. Chemcal weathering: anything with chemicals in it like carbonation, hydrolysis, solution, oxidation and hydration.

Exfoliation of bodies of granite rock can occur from chemical weathering of the surface, differences in temperature, salt crystallization, and release of pressure.
Exfoliation is primarily caused by physical weathering processes such as thermal expansion and contraction, where daily and seasonal temperature changes cause rocks to expand and contract, leading to the outer layers of rock peeling off in sheets. This process is especially common in areas with extreme temperature fluctuations like deserts.

Therew is only to types of weathering in my knowledge and they are Mechanical and Chemical (in scientific term). Mechanical is also know as physical.

Frost wedging & exfoliation are common terms associated with mechanical weathering.
•Aeolian • •Biological weathering • •Exfoliation • •Thermal Expansion
In some case chemical weathering can cause this (where new crystals form from old ones but where the volume of the new crystals is not the same as the original). In other cases the weathering process is temperature driven by water entering the porous layer of a weathering rock and freezing. This can split the rock parallel to the surface, giving it exfoliation layers. Some texts also imply that exfoliation domes are produced by by removal of vertical pressure relieving paleo stresses in the rock, this however would not be a weathering process.
