A laundry sink tub is a useful addition to the home. Although the name suggests that it is built for laundry purposes, it can have other functions as well. It can be used to pre-soak laundry, chill bottles of soda or beer for a party, and has many other useful functions.
Unlike other kitchen or bathroom sinks, a laundry sink tub has a larger area and a greater depth. However, like other types of sinks or tubs, it can also get stained by hard water, soap scum, and lime build-up. To remove the stains, here are some methods that can work.
Step 1 - Start with a Gentle Solution
With regular cleaning, the laundry sink tub can be cleaned easily using a damp cloth pre-dipped in warm water. Simply rub the cloth or rag onto the surfaces of the tub to remove the stains.
To remove hard water stains, prepare a vinegar solution by mixing one part of white vinegar with one part of water. Fill a spray bottle with the solution. Spray the hard water stains with the solution and allow it to sit for about 10-minutes. Rub the stains with damp cloth afterwards.
Step 2 - Use a Cleaning Paste
There are instances when soap scum and lime build-up cannot be removed from the tub gently. Although scrubbing the tub with an abrasive sponge or scrub can remove these build-ups easily, this should never be done because it will destroy the surface of the plastic or stainless steel sink tub.
A safer solution is to use a cleaning paste made out of baking soda and a solvent. The solvent can either be vinegar or lemon juice. Slowly mix the vinegar or lemon juice with baking soda. Never pour the solvent hastily into the powder because it will produce a lot of bubbles.
When a consistent paste is made, apply it to the lime build-up or soap scum. Allow the paste to stay on the affected surfaces for about 10-minutes before rubbing with a damp rag or cloth. Rinse with water afterwards and repeat the process if necessary.
Step 3 - Use Bleach to Clean Molds and Mildew
For molds and mildew, use one part of bleach and four parts water. Mix the solution and use a spray bottle to spray it on the affected areas. Make sure to use oxygen bleach because it is safer than the chlorine counterpart. Spray and leave for ten minutes. Scrub the stains with a damp cloth and rinse thoroughly with water.
Step 4 - Use Muriatic Acid as a Last Resort (for Plastics Only)
Use one part of muriatic acid mixed with ten parts of water to clean hard-to-remove stains on plastic sink tubs only because it will corrode metal. Spray the solution onto the stains and rub with a damp cloth. Always wear rubber gloves when working with this chemical. Rinse the chemical thoroughly with water.
