I've noticed that a really easy way to clean part of the toilet bowl is to pour some bleach into it. However, above the water-line in the bowl, the bleach can't affect. If you try to add more, it simply drains out the hole at the bottom of the bowl.
So, Plug That Hole. Then you can add water and bleach until the bowl is full, let it set for a time, for thorough cleaning, and then pull the plug out. Simple!-- Vernon, Oct 10 2013 Maybe no toilet ducks in Vernon country, but ... http://www.vernoncounty.org/ [normzone, Sep 21 2016] I had to google toilet ducks ... http://www.jantoo.com/cartoon/01235859 [normzone, Sep 21 2016] What would the plug be made of? Flexible and bleach resistant is a tough combination.-- bungston, Oct 10 2013 Silicone is probably flexible and bleach-resistant enough.-- Vernon, Oct 11 2013 this is why they make clingy-thick and usually blue toilet cleaners. squirt 'round the rim, swish round with the brush, and you've got a clingy blue tinge for at least 10 mins. Toilet cleaned.-- bs0u0155, Oct 11 2013 Couldn't you just stick a plunger in it?-- xandram, Oct 11 2013 Or, just reproduce and have your offspring clean the toilet. That's what I do -- works brilliantly.-- awesomest, Oct 11 2013 //Silicone is probably flexible and bleach-resistant enough.// Unlikely. The UK's first ultra-high- altitude reconnaissance aircraft, the Scimitar, was scrapped largely due to fatal accidents involving both of the early planes. It was later discovered that the sudden failure of the pressurisation system was caused by embrittlement of the (then newly- developed) silicone window seals caused by ozone, which has much the same effect as bleach.-- MaxwellBuchanan, Oct 11 2013 [MaxwellBuchanan], there are two different ways to respond to your objection. First is that quite a few years have passed since silicone was "newly developed", and likely the improvements made since include greater resistance to such things as bleach.
The second way to respond involves examining the Chemistry of the situation. You know that Fluorine is the highest-grade "oxidizer", and that Oxygen is second, and the Chlorine is third. Oxygen is second mostly because it can exist in the form of ozone. Nevertheless, Chlorine normally does not easily replace Oxygen in various chemical compounds, and silicone contains quite a bit of Oxygen.
Now, some silicones include Hydrogen attached to Silicon, and here is where Chlorine could be detrimental, since it can steal the Hydrogen away from the Silicon. On the other hand there are other silicones that include Fluorine instead of Hydrogen, attached to the Silicon. Chlorine won't affect such silicones at all....
[xandram], my answer to your question is in the next paragraph. As an aid to visualizing this Invention, Let Us Consider a kind of "bag" of tough silicone, having an appearance somewhat like the silicone implants used in breast-enhancement surgery. We've made sure that the particular silicone we are using is denser than water, and we attach a handle to it.
So, when immersed into a toilet bowl, the shape of the bag is able to distort in many different ways, ensuring that we can get a pretty good watertight seal as we place it against the drain- hole. The Average Plunger Cannot Fit That Way Into All The Different Shapes Of Toilet Drain Holes.
When we add water to the toilet bowl, there will be an increase in water pressure against the distorted bag plugging the drain-hole. So we want to make sure that part of the bag is less flexible than the rest; we don't want the whole bag to suddenly attempt to go down the drain (the handle will interfere, but it would be better to prevent such a problem from happening in the first place).-- Vernon, Oct 12 2013 What about using a ceramic or glass plug using the sort of taper fittings that chemists will no doubt be familiar with?-- TomP, Oct 12 2013 Something soft and pliable is likely to get flushed by mistake.-- the porpoise, Oct 12 2013 [Vernon], it's not strictly necessary to capitalize the names of chemical elements. Nor, for that matter, Chemistry. There are exceptions, of course; for example the town of Bromine, Ill. is capitalized, as of course is the surname of Rex Carbon.-- MaxwellBuchanan, Oct 12 2013 It is not unknown for crafty rats to come up through the toilet bowl. Such a device could be left in place to prevent this.-- corvuscornix, Oct 19 2013 Folks, today I tried a water balloon --an ordinary lung- inflate-able balloon instead filled with water-- and it seems to work fine, to fit the toilet drain and plug it. It works because the water-filled balloon has a larger diameter than the water level in the toilet bowl. Simple and cheap!-- Vernon, Sep 21 2016 Thrilled for ya, I'm sure :)
My porcelain throne was designed and made in a place where they eat lots of rice, which I like to imagine is the reason the outflow pipe is smaller than normal, rather than because it was 50c cheaper to produce. So, no problems getting it to plug up.-- FlyingToaster, Sep 21 2016 random, halfbakery
