You should not use any specific product, which in fact could be so aggressive as to completely ruin the mattress, without completely dissolving the stain. The best advice that can be given in this case is to use steam.

First we act with the hot jet, closely, over and over again, because one alone does not solve the problem. With multiple jets you dissolve dirt, stain and the ring itself. The stain should be much less visible by now. Then clean the area thoroughly with hot soapy water, rubbing thoroughly with a clean sponge. Once done, it is placed in the sun, or dried as well as possible.
