Things You'll Need
Undiluted white vinegar or lemon juice
The wet, humid conditions found in showers make it an easy target for rust and hard water stains. If all the water fails to drain completely out of the shower and instead pools on the floor, the lining of the shower can begin to rust, leaving a reddish-brown stain. Excessive minerals in the water source creates a condition known as hard water, which leaves behind lime and mineral deposits. While homeowners can purchase commercial cleaning chemicals to eliminate stains and rust on the shower floor, homeowners can also take advantage of natural, homemade alternatives.
Pour lemon juice or undiluted white vinegar directly on the rust and stains on the shower floor. Cover the stain completely. Allow the liquid to sit for two to three hours.
Turn on the shower to rinse the liquid down the drain. Leave the shower running for a moment to fully neutralize the acids in the lemon juice or vinegar.
Scrub the area with a sponge to dislodge any loose deposits. Inspect the area for any remaining stains.
Mix lemon juice or white vinegar with baking soda to form a thick paste if remnants of the rust and stains remain.
Spread the paste over the remaining stains and allow the mixture to sit. Scrub the area vigorously with a sponge after two or three hours pass.
Turn on the shower and rinse the solution down the drain. Again, leave the shower running for a moment to neutralize the acids in the vinegar or lemon juice.
