White vinegar provides an environmentally safe means to remove mildew and other stains. You apply it with a rag or sponge. Leaving it on for a few minutes allows the mild acid to remove stains. Using a brush on the vinyl pool liner after applying vinegar helps to remove stains and debris.
Punk rock (or simply punk) is a rock music genre that developed between 1974 and 1976 in the United States, United Kingdom, and Australia. Rooted in garage rock and other forms of what is now known as protopunk music, punk rock bands eschewed perceived excesses of mainstream 1970s rock.
As derided as pop-punk often is among the more hardcore set - it's probably more true to the spirit of Johnny Ramone than a lot of other bands were. The Ramones certainly didn't originate the scaling down of rock music - that had already been happening with people like Jonathan Richman as far back as the early 70s. One could even make a case for bands like The Kinks being the first punk groups.
