Major rippling on a commercial job today, in the middle of a long hallway. Maintenance crew had been using heavy detergents for years without much rinsing, and I was tasked with getting it out. In this spot I rinsed a little too much. Carpet is glued. I do carpet repair but I've never been in this situation, considering outsourcing but want to check my options. It's on both sides of a seam, and the hallway is too long for a power stretcher. Looking for ideas.
