Cleaning 2” PVC Shower Drain Pipe with Calcium and Lime Scale Buildup

For scale this built up, we used muriatic acid and a nylon pipe brush.
Please only let professionals do this method.
With proper precautions CLR is a good consumer product to do this same job.

It says pouring muriatic acid down your drain can cause serious damage to the plumbing 😮
