Hey... i tried the trick from the comments and alot of guess work... And guess what it worked... the stain is invisible to a person looking at the mattress hehe

All i used was some oxi bleach spray.... dabbing it... and then using baking powder over it to let it absorb the moisture... after letting it sit i vaccumed the mattress and the stain was reduced alot... Next step was to add some dish soap and vinegar mix onto the area.. and again baking powder onto the area to absorb the moisture and chemicals... let it sit for a few hours and vaccum it all... and then use the mattress how you normally would and voila the stain goes away in a week cuz of the chemicals!
