THE THINKING BEHIND STAINLIST
A little knowledge.
A longer life for your things.
Stain List is a practical removal reference organized by stain type: what chemical or mechanical action actually works, what temperature matters, and when a stain is set and won't come out regardless of effort. The guides cover common fabrics (cotton, wool, polyester, denim), carpet, and hard surfaces, with methods ordered by what most people already own before suggesting anything specialty.
How We Approach a Stain
We test claims against textile chemistry literature and commercial laundry practice, not brand marketing. Articles name exact concentrations, dwell times, and water temperatures where those details change the result. If a method does not work reliably, we say so.
