Is it safe to use 91% isopropyl alcohol regularly?

I have a cheap Hello Cake anal vibrator. It has an odor. I read that silicone has very small pores and cannot trap bacteria or even viruses, but odor molecules are much smaller so they can trap odors. After every 2-3 uses I wash and dry it and soak it with 91% isopropyl alcohol, which I read can be used to eliminate odors. I let it air dry and the odor was gone. Will this damage the toy over time?
