I actually try to error in the opposite direction and give my customers a reality check – depending on what the stain was caused by, and how deep it penetrated the surface, etc., there is no one on the planet that can guarantee it will not return with time, humidity, etc. However, with the application of our stain protector, I can tell them we can prevent further spills, etc. from becoming a future problem. So far, everyone seems to understand this and appreciates the honesty.
