They are not always noticeable and vinegar is often not strong enough, even when the rocks really aren't suitable. A stronger acid is required to really be sure. Concentrated Seachem Acid Buffer works well.

If you have access to swimming pool or spa supplies, the muriatic acid sold for that use is very good for checking rocks. Just be very careful when using that or any other strong acid.
