Cleaning and Stain Removal - Blood stain returned!

I have a brand new (2 month old) mattress. My 4 yr old granddaughter slept in the bed and had a nosebleed in her sleep...it went straight to the mattress!! I used hydrogen peroxide immediately with cotton and it all came up. However, when I got home from work that night, there was a HUGE stain where the smaller stain was! What happened? The outer edge of stain is blood tinted. What can I do now?

Thank you VERY much!!

Going to take a wild guess.

When you cleaned the surface it did not remove the blood that had gone through to the mattress filler. Then the dampness on the surface from your cleaning helped to wick the underlying blood out of the filler into the surface material.

Possibly once the blood in the filler is dried it won't be a problem, but when you reclean the surface stain it might re-dampen the blood underneath.

Should be a more expert cleaner along with the definitive answer, but I would be thinking something along the lines of dampening the area and then trying to draw it out with something powerful like a shop-vac. The ultimate solution would be a professional upholstery cleaner who would have the necessary equipment.

Did you happen to pour the peroxide onto the spot? If so it waterpooled it. I would go back and put the peroxide in a spray bottle..spray the area let it foam up and rinse and blot with a white rag until no more blood comes up.

I agree - you probably put too much peroxide on and it soaked down into the mattress.
