Toilet bowl cleaners having inner and outer water-soluble envelopes are disclosed. The inner envelope contains a basic material and the outer envelope contains both the inner envelope and an acidic material. In use, the outer envelope dissolves and thereby releases the acidic material to clean the toilet bowl. The inner envelope then dissolves thereby releasing the basic material contained therein to neutralize the toilet bowl water.
