The haze is probably from the grouting process. You can buy a grout haze remover solution from most tile stores if you'd rather not use the vinegar. Remember that vinegar is acidic so it will need to be rinsed well and can cause dulling of some tiles if it is left on too long.
Protonix Linked to Hip Fractures. Protonix (generic: pantoprazole) is just one of a few antacid medications that are called proton pump inhibitors. Other common proton pump inhibitor drugs include Aciphex, Nexium, Prevacid and Prilosec. Protonix is manufactured by Wyeth-Ayerst Laboratories and gained FDA approval in 2000.
Antacids are available over the counter and are taken by mouth to quickly relieve occasional heartburn, the major symptom of gastroesophageal reflux disease. Treatment with antacids alone is symptomatic and only justified for minor symptoms. Antacids are distinct from acid-reducing drugs like H2-receptor antagonists or proton pump inhibitors and they do not kill the bacteria, Helicobacter pylori, which causes most ulcers.
