Neither Vinegar nor Baking Soda: What People Are Putting in the Toilet Before Scrubbing
Toilet stains often send people toward vinegar, baking soda or another bottle of cleaner. Another method starts somewhere unexpected: the freezer. Ice cubes go into the toilet bowl with coarse salt, where the two sit for several minutes before the toilet brush comes out.
Salt adds a mild abrasive that can help loosen residue during scrubbing. Ice fills more of the bowl with solid material instead of disappearing into the water, giving the salt something to collect around before the mixture gets moved across the porcelain with a brush. The method has also appeared in cleaning videos, including this demonstration on YouTube.
Start with a cup of ice cubes
Pour about one cup of ice cubes into the toilet bowl. Unlike another cup of water, which joins the water already sitting in the bowl, the cubes remain solid while the cleaning process starts.
Ice has appeared in other toilet-cleaning methods for the same reason. Filling part of the bowl with solid cubes can keep cleaning material around the sides of the bowl instead of allowing everything to settle beneath the waterline at once.
There is no need to pack the bowl with ice. One cup is enough for the salt-and-ice version of the method.
Add coarse salt over the ice
Sprinkle two to three tablespoons of coarse salt over the cubes. Coarse crystals are the useful part here because they provide some abrasion when the mixture is moved around the bowl.
Let the ice and salt sit for about five to 10 minutes. Some of the ice will melt during that time, leaving cold water, ice and salt together in the bowl.
Claims surrounding this trick sometimes go further, suggesting salt can disinfect a toilet or kill bacteria in the drain. A few tablespoons diluted in toilet water should not be treated as a disinfectant. Salt can have antimicrobial effects at high concentrations, but that does not make this mixture a replacement for a tested disinfecting product.
Move the mixture around with the toilet brush
After the wait, use the toilet brush to move the ice, salt and water around the inside of the bowl. Focus on visible residue and marks around the waterline rather than expecting the cubes to clean areas on their own.
Salt contributes abrasion as the brush moves it across the porcelain. Ice can also help keep the mixture distributed through more of the bowl while it remains solid.
Flush once the bowl has been scrubbed to carry away the remaining salt and melting ice.
Ice and salt won’t clear a clogged toilet
Some versions of the trick claim flushing ice through the toilet can scour the internal trap, remove buildup from pipes or improve a slow flush. Those claims go beyond what this cleaning method can be expected to do.
Ice sitting in the bowl has little force against hardened mineral deposits, and salt does not turn the mixture into a drain cleaner. A toilet that drains slowly or backs up needs the cause of the blockage addressed rather than more material added to the bowl.
The same distinction applies to hard-water scale that has built up over time. Ice and coarse salt may help with loose surface residue during scrubbing, but established mineral deposits often need a cleaner designed to dissolve them.
Think of it as a step before scrubbing, not a replacement for cleaning
Ice and salt make the most sense as an extra step in a normal toilet-cleaning routine. The salt supplies some abrasion, the ice gives the mixture bulk in the bowl, and the brush still provides the scrubbing that removes residue.
That also explains why the method starts before the brush comes out rather than replacing it. Once the ice begins melting and the salt has been moved around the bowl, finish the job with the same scrub and flush the toilet would normally get.
Would you put ice cubes and coarse salt in your toilet before scrubbing, or stick with your usual cleaner?
