Use on most bathroom surfaces including: porcelain, ceramic tile, shower doors, sinks, bathtubs, white grout and caulk, toilet bowls, and fiberglass. Will not remove rust. Do not use on vinyl, natural stones, mirrors, plastic laminates, wood, fabrics, painted, coated or sealed surfaces, colored grout or wall coverings.
INSTRUCTIONS: TO CLEAN TUBS, TOILET BOWLS, SINKS, PORCELAIN, CEMENT, STUCCO and BRICK: Mix equal amounts of CLR and warm water. Apply directly to calcium, lime or rust with brush, cloth or sponge. Rinse promptly with cold clean water. If stain does not disappear, use CLR full strength, wipe and rinse promptly.
DO not use CLR on natural stone or marble, terrazzo, colored grout, painted or metallic glazed surfaces, plastic laminates, Formica, aluminum, steam irons, leaded crystal, refinished tubs or any damaged or cracked surface. CLR may etch older sinks, tubs and tiles. CLR is corrosive.
A baking soda and vinegar solution is perfect for cleaning a porcelain sink and removing stains. Make a paste out of the two ingredients and use a soft-bristled brush (such as an old toothbrush) or cloth and your finger, to apply and scrub the stained area.
Hydrogen peroxide, the active component of oxygen bleach, gives baking soda an added punch to clear any yellow stains. For antique or colored porcelain, hydrogen peroxide and oxygen bleach are the most effective household cleaners for tough stains.
CLR or Lime Away? An acid-based cleaner is the best way to remove water deposits. Vinegar and lemon juice are two natural alternatives, but they just don't work as quickly and effectively. CLR uses similar ingredients to Lime Away.
No. The two products have different ingredients and, as is true with any cleaner, should never be mixed with another cleaner.
Borax and Warm Water
You cannot ask for better natural and all-purpose cleaner than Borax. You can use it to clean various surfaces, like your porcelain sink. All you need to do is prepare a paste using the Borax and warm water. Then apply the paste over the stains and leave it for a few hours.
The brown stain is from a large amount of iron in your water. It is closely related to simple rust that you see on metal, which is iron oxide. Your water probably comes from groundwater that filtered through rocks containing iron-rich minerals on its way to the well.
White vinegar is an excellent remedy for lime scale. It is very economical and very efficient, both for tiles and for taps with lime scale. Pro Tip: go for the white vinegar from the food section, it is usually cheaper than household vinegar. As with the lemon, leave on for ten minutes and rub with a sponge.
Don't mix CLR with other household cleaners or bleach.
Mixing acids with bleach creates toxic chlorine gas. Mixing with other household chemicals can also result in toxic fumes.
Does CLR get rid of hard water stains? Yes, for stubborn hard water stains on shower walls and tiles, bathtubs, sinks or faucets that need more scrubbing power, you may have to use something stronger than vinegar, like CLR Brilliant Bath Cleaner, a top-tested product that won a 2020 Good Housekeeping Cleaning Award.
Remember to wear gloves and protect your eyes and clothes in case any cleaning product splashes you during the process. Pour equal parts of lemon juice and white vinegar into the toilet bowl, leaving it for at least one hour before scrubbing with a toilet brush. The scale should come away easily.
White vinegar is usually 95 percent water and 5 percent acid. By contrast, cleaning vinegar contains up to six percent acid and is around 20 percent stronger than regular white vinegar. That means it can help you power through some tough household chores with a lot less hassle — and less muscle!
