From my experience, the basic stuff actually goes a long way — regular hot water flushes, using a drain screen, and avoiding grease down the sink make a big difference. Baking soda and vinegar can help with minor buildup, but once the line is really clogged, DIY methods usually just slow it down temporarily. In those cases, I’ve seen options like high pressure drain cleaning Amarillo mentioned as a more thorough way to clear everything out instead of just poking a small hole through the blockage.
