I am a smoker and I can smell smoke on a person, house, fabric etc. I have non-smoking rooms in my house - the bedroom and the sewing room are two of them. I never get a smoking room at a hotel because they reek of smoke and I can't sleep. I've brought my quilts to work to have non-smokers sniff them for smoke - they passed :)
Can't believe a professional long-arm person would smoke around her customers products. That's incredibly rude.
Amonia ... just one word of caution about amonia. To a dog (and possibly cats too) amonia smells like urine. This is why you NEVER clean the area a dog soiled with amonia - to the dog - it smells like the proper place to potty. So if you wash your stuff in amonia and have dogs, don't be surprised if your dog thinks it's a great place to potty (especially the boys, and in particular intact boys, as they tend to "mark").
