Use a mild cleaner for daily toilet polishing. Unless the toilets are already in good shape, clean them first and then use a separate disinfectant. Use acid cleaners only when you have really stubborn stains to remove. Acid cleaners are very dangerous - always protect yourself by wearing gloves and goggles. Also use a disinfectant product that contains Alkyl Ammonium Chloride to kill germs.
Some suppliers combine the cleaner and disinfectant into one product.
You can use a combined cleaner-disinfectant only if the toilet fixtures are not too dirty to start with. Otherwise you should clean the toilets first, and then use a separate disinfectant. Leave the disinfectant in place for 10 minutes to get good results. Stain Removal - Sometimes lime stains, rust, or other stubborn dposits will form in the toilet bowl. Your regular daily cleaner might not remove these materials.
