Oh no, dealing with a period stain on the sofa is super frustrating, but don't worry, it's a common problem with some good solutions! Based on advice from others who have tackled this, the key is to act as quickly as you can and always use cold water.
Your first step should be to blot the fresh stain gently with a clean cloth or paper towel to absorb as much as possible. Avoid rubbing, as this can push the stain deeper into the fabric.
A great starting point for cleaning is a simple mixture of cold water and a little bit of dish soap. Dampen a clean cloth with this solution and gently dab at the stain from the outside in. Keep dabbing with a clean part of the cloth until the stain lifts.
If the stain is stubborn, hydrogen peroxide can be very effective, but you must be careful. Hydrogen peroxide can act like bleach and may discolor your sofa's fabric. It is absolutely essential to test it on a hidden spot first, like a seam on the back or underside of a cushion. If the test spot is fine, you can apply a small amount of peroxide to the stain, let it bubble for a minute, and then blot it up with a clean, cold, damp cloth.
Another option mentioned is a commercial carpet and upholstery cleaner, specifically an enzymatic cleaner designed to break down protein-based stains like blood. Products like Folex are often recommended for this purpose. Just be sure to follow the directions on the product label and, again, always spot-test first.
