Sinks, Tubs, Porcelain Toilets, and Ceramic Tile
A way to safely and effectively clean these surfaces is to grab mild soap, sponges, towels, white vinegar, and baking soda. In a bowl, combine hot water with a couple of drops of mild soap, and using a sponge or rag, clean the surface.
Simply pour a kettle of almost boiling water into the bowl, follow up with 250ml of citric acid, and leave it for some hours – preferably overnight. The next day, scrub and flush. What's good for those caked-on pots and pans after cooking dinner is also good for removing a brown stain on the bottom of the toilet bowl.
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.
Skin Mild Irritant. Prolonged contact may cause dermatitis, and itching. Inhalation No adverse effects expected under typical use conditions. Ingestion Oral burns, vomiting, and gastrointestinal disturbance.
While the bowl's wet, sprinkle a few tablespoons of baking soda into the toilet bowl. Concentrating it on stain rings is great, but focus on getting it all over. You should see the reaction between the vinegar and the baking soda; this reaction helps to mitigate buildup without damaging the porcelain.
Avoid Abrasive Cleaning Compounds
It may be tempting to use bleach, hydrogen peroxide, and the like, but it's best to avoid these cleaning agents as much as possible. It's not likely that the chemical compounds above will crack your porcelain toilet, but they can damage the finish of the porcelain.
For regular cleaning, just sweep away debris, wipe with clean water, and thoroughly dry. For deep cleaning, use a pH-neutral or mildly alkaline detergent. Use a nylon or plastic scrubber, if needed.
Things to Avoid
Stay away from products with bleach or ammonia because they can change the tile or grout coloring. If you need to scrub your floors, make sure not to use any brushes with hard bristles since they can scratch the porcelain surface.
We recommend using a 50/50 solution (equal parts of CLR Calcium, Lime and Rust Remover and warm water) into a glass or porcelain bowl. Apply solution to the affected stained areas of the glasses using a damp cloth or sponge. After 2 minutes, rinse thoroughly with cold, clean water.
Put a cup of hydrogen peroxide in a spray bottle. Spray evenly over the porcelain. Let the hydrogen peroxide sit for 15 minutes to an hour. Rinse and buff with a microfiber cloth for a clean, bright shine.
Mixing chlorine bleach and cleaners like dish soap can be harmful to your health. Mixing bleach with other cleaners can release toxic gases.
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!
Cleaning with a mixture of baking soda and vinegar in the bathroom can work really well. To clean your toilet with vinegar, pour a cup of vinegar in the toilet bowl and let sit overnight. The next morning, sprinkle a little baking soda into the bowl, scrub, and then flush clean.
If the clog still seems to be intact, start over at step 1 and repeat the process a couple of times. For extra-stubborn clogs, you can let the fizz mixture sit overnight or combine this method with plunging.
A much better solution is to use some WD-40 Multi-Use Product. Most people don't know that WD-40 can solve many of their household cleaning needs quickly and easily. When cleaning a toilet bowl, WD-40 works by softening the rust and lime deposits, so they can be easily wiped away. You don't need to use much of it.
How to Remove Calcium Buildup. White vinegar, baking soda and even a lemon can be used to get rid of pesky calcium stains. Many homemakers already use vinegar to help clean difficult areas. It's also helpful when addressing hard water stains or calcium buildup.
