INEFFECTIVE against Hard Water deposits
This is not "the Works" solution that used to be available with a much higher percentage of Hydrogen Chloride.  At 9.5% Hydrogen Chloride, the current version is useless against lime and other deposits from hard water.  The product used to have a 20% HCL and was very effective against hard water.  Very disappointed!  The image on the listing is just blurry enough to mask the true HCL content; so misleading.
