A related topic is dispensing tests. These are especially important for the in-tank toilet bowl cleaners. Usually the brute force method is used whereby the product is placed in an actual toilet tank, and the number of flushes to exhaust the product is measured. Alternatively, the product can be placed in a container of water the time required for the solid tablet or puck to dissolve completely is measured. (This is not relevant for liquid automatic cleaners.) The difference between the two methods is that the first uses repeated aliquots of fresh water to dissolve the item (as in real use), whereas the second uses the same volume of water for the whole experiment. 

Acid Cleaners are used with extreme caution. Bowl cleaners are generally acidic in nature, and are available in powder, preferred solid block or liquid form. The function of toilet cleaners is to remove effectively fecal soils, lime and rust deposits, and urinary calculus from commodes and urinals.
