<p>[QUOTE="-jeffB, post: 3594730, member: 27832"]The stuff we used to buy is called "The Works", and it's 9.5% HCl, with water and some surfactants making the balance. I don't know what surfactants work well in 10% HCl, but I figured I could make up my own somewhat-diluted solution from hardware-store muriatic. It smells stronger than the store-bought stuff, but the lack of detergent doesn't seem to make much difference in performance.[/QUOTE]</p><p><br /></p>
