To remove water stains from a mattress, blot and vacuum the stain, apply shampoo, and let the surface dry. You need rags, water, a vacuum with an upholstery attachment, upholstery shampoo, a brush, a sponge, some vinegar and some baking soda.
- Blot and vacuum the stain
Check to see if the stain is still wet. If it is, try to blot it with a rag to soak up some of the moisture before it has time to settle in. Once the stain is dry, take your vacuum, and attach its upholstery nozzle. Use the vacuum to remove any dirt or loose particles from the stain.
- Apply shampoo, and blot
Follow the instructions on your upholstery shampoo to find out how much water you need to use to dilute it. Then, soak a sponge with some of the shampoo, and delicately apply the mixture to the water stain. Try not to over-saturate the mattress. Clean the sponge, and then soak it in vinegar. Apply the vinegar to the same areas as you applied the shampoo.
- Let the surface dry
Leave the mattress to air dry. Once it is dry, consider sprinkling some baking soda onto the mattress to get rid of any lingering odor.
