3. Force the brush tip back and forth, especially along the toilet jets (holes under rim), around the water line and on visible stains. Scrub until stains are gone, reapplying cleaner as necessary, then flush twice.

4. Soak the entire faucet surface from base to tip with an all-purpose bathroom cleaner, or use a lime-removing product if the buildup is extremely thick and crusty.

5. Scrub the surface with an old toothbrush, pushing bristles into crevices on the end of the spout (aerator and screen) and on the handles, as well as at the base of the faucet.

6. Once all deposits have been removed, rinse the cleaner off immediately by wiping the entire surface down with a dripping wet sponge. Dry and polish with a soft cloth.

7. Coat the entire tiled surface (grout, caulk and all) with an all-purpose cleaner that attacks soap scum. Wait 5 to 10 minutes to allow the product to work, which saves your scrubbing elbow.

8. Remove remaining visible scum and deposits by applying light pressure with a non-scratch nylon scrubber. Reapply product to difficult areas and scrub until clean.

9. Remove stains and deposits on grout or caulk by lightly scrubbing back and forth with a grout brush or old toothbrush. Reapply product as needed.

10. Rinse the entire tiled surface thoroughly with a dripping wet sponge. Push it back and forth across the top of the wall so rinse water streams to the bottom of the wall. Repeat until all cleaner is removed. Then, start at the top of the tile with a bathroom squeegee and move downward to remove as much water as possible.
White vinegar works as well as Lime-away.
Would like help with a water/hard mineral stain in the bathtub. These hints are great.
