Muriatic is nasty and not very effective. Pour a mix of draino/lye/water inside for a day and it'll rinse out clean. Then save the mix because, though it'll look dirty, it can be used over and over.
Effective, depending on what you're trying to dissolve. I've used it with plenty of success for 35 years and with the same batch at that.
