Spray cleaner with sequestrants
Large sponge with abrasive and soft sides
Lime deposits are the result of minerals (calcium and magnesium) reacting chemically with the soap scum, body sweat and other substances in your bathtubs, toilets, showers and sinks. These minerals leave lime deposits and nasty-looking stains. The good news is, you can remove the lime deposits; the bad news is, you have hard water and need to get a filtration system. Special cleaners that contain sequestrants are made to tackle lime deposits. This is the key ingredient for getting rid of lime deposits.
Spray the surface that contains lime deposits. Lime-A-Way and CLR are examples of sequestrant-containing cleaners. You can purchase these items at any home improvement store or online.

Rinse with warm water.
Spray again, and let sit for 10 minutes.
Clean the surface with the soft side of the sponge until spotless.
Repeat this process as needed.
