Review: Great drain cleaner - My AC man recommended this product to keep my AC condensation line clear. So far no clogs and seem to work well. Two points though, follow the instructions thoroughly and if it gets on your skin walk off right away. This is strong stuff!
Review: Works Well - My AC unit, like many others, has a tendency to back up when used heavily, especially in the summer months. I've used bleach and vinegar with some amount of success, but someone mentioned this stuff works very well. All I can say is, so far so good. I've used it for about 4 months now and had zero issues. I even vacuumed the line to check performance, and there's none of that white slime or excess water buildup. I've only placed it in the line and not directly into the pan. That's next to try to ensure a summer free of AC stoppage.
