Kleenex does break down but it does not break down like toilet paper does.
It takes longer for Kleenex or other tissues to break down than toilet paper so it's best to throw Kleenex and other tissue into the trash.
It is okay to throw toilet tissue or toilet paper in the toilet but if you mean tissue paper for blowing your nose then it's best to throw those in the trash.
Although throwing one tissue in the toilet and flushing it should do no harm but flushing more than one tissue in the toilet could cause a toilet clog.
A good chemical that can dissolve toilet paper is RidX Septic Treatment.
The RidX septic treatment is designed to break down and dissolve toilet paper and other waste.
Vinegar and baking soda also works to dissolve toilet paper.
Toilet Paper does dissolve in water eventually.
Toilet paper is made and designed to break down quickly in water so as long as you use small amounts of toilet paper in the toilet it should flush down just fine.
However using too much toilet paper can clog the toilet.
When you have toilet paper in a sewer line clogging the sewer line you can pour some RiDx down the toilet to help dissolve the toilet paper in the sewer line.
Also using a sewer auger can help break the toilet paper up and get the clog removed.
Another way to get rid of toilet paper in a sewer line is to use some baking soda and vinegar.
Pour 1 cup of baking soda into the toilet.
Pour 1 cup of vinegar into the toilet.
Pour 4 cups of boiling water into the toilet.
RidEx does dissolve toilet paper.
RidEx is meant to dissolve toilet paper, waste and even grease in your septic system.
The enzymes in RID-X® begin working as soon as they come in contact with water.
The bacteria take 2-4 hours to germinate and then begin to break down solid waste.
If the temperature and conditions are favorable, then the bacteria will multiply to the maximum level that the environment will allow in about 2-4 days.
You can put RidEx in every toilet but you don't have to as long as you put enough RidEx down the toilet so it reaches the septic tank.
You can put RidEx in the toilet.
RidEx can be poured in the toilet or down any drain that leads to the septic tank.
As long as the RidEx gets into the septic tank it doesn't matter which drain you pour the RidEx down.
RidEx is a bacterial septic tank treatment and is a bacterial enzyme that breaks down waste in septic tanks, but it can also be used for all waste systems in your house.
Applied regularly, RidEx will “clean” the inside of the pipes by breaking down the solid waste stuck to the pipes.
RidEx does not clear clogged toilets.
However if the clog is something such as a bit of toilet paper then the RidX may help break down the toilet paper and clear the clog.
If your toilet is clogged though you need to use a toilet auger or plunger to help clear the toilet clog.
Or if the clog is further down in the line you need to find the clog and remove it with a drain line cleaner or sewer auger.
RidEx is not meant to unclog toilets.
Instead RidEx is a septic tank treatment that is used in the tank to break down the solid organic waste material.
Its job is to break down the solid waste making it soluble where applicable.
If insoluble, it is broken into smaller particles that form sludge at the bottom of the tank.
Some toilets do eventually unclog themselves.
For example if the toilet was clogged by too much toilet paper, too much poop etc then the toilet will eventually unclog itself as the poop or toilet paper dissolves in the toilet.
However some other clogs will need intervention to clear the toilet clog.
Pouring boiling water down a toilet can sometimes unclog the toilet.
However you should not pour boiling hot water down a toilet unless the toilet is a stainless steel toilet or plastic toilet as the boiling hot water can crack a Porcelain Toilet.
Pouring boiling water into your toilet bowl can cause the toilet to crack, which would leave you in an even worse situation.
Fill the toilet with the hot water.
The heat, combined with the movement of the water, should help to break up and remove the toilet clog.
If the toilet clog is not too bad then letting the clogged toilet sit overnight is okay and in some cases less severe toilet clogs will clear themselves.
In more severe toilet clogs you need to work to clear the clog as the longer the clog sits the worse it can get.
Toilets, like all plumbing drains, work by the force of gravity.
A full bowl of water exerts its own pressure on the clog and, over time, often will clear the clog for you.
So if you have more than one bathroom in the house, just wait it out overnight, or as long as you can.
Then, try to flush again.
If you try to flush or you flush a clogged toilet then the toilet water will back up over the bowl and run out over the toilet bowl and onto the floor.
Sometimes you may need to use a can or something or a pump to remove some of the water in the toilet bowl to help clear the clog.
If you flush the toilet and the toilet water backs up into the bathtub or sink then the clog is somewhere between the toilet and the tub or sink drain line.
In most cases the toilet, bathtub and sink all connect to the same drain which then leaves the house connected to the main sewer line.
Your toilet drain line has a few other connections that are then connected to the sink, tub etc,
So most likely the clog is in the large pipe after it leaves the toilet drain.
When flush toilet water comes up in the tub, it means the blockage is located somewhere past the point of connection.
Otherwise, water would simply back up in the toilet.
The tub drain is usually at a slightly lower elevation than the toilet, so it provides a way for the flush water to get out of the pipe.
Baking soda and vinegar can clear and unclog some toilet clogs.
However if the toilet clog is more severe then you may need to use a toilet plunger, toilet auger or if it's really severe you may need to replace the toilet.
The clog may also be down the line before it reaches the actual sewer line to leave your house or the clog may be between the toilet sewer line and another part of the sewer line.
If the clog in the toilet isn't too severe or if the toilet isn't clogged by something such as a toy etc then baking soda and vinegar can work to naturally unclog a toilet.
To unclog a toilet using baking soda and vinegar take a cup of baking soda first and pour that down the toilet then if the toilet doesn't have too much water in the toilet bowl pour some boiling hot water down the toilet and then add some vinegar from the bottle slowly and allow it to sit for 30 minutes to an hour.
Then try flushing the toilet again.
If it doesn't flush yet then you may need to try plunging it to help the clog along through the pipes and then might have to use the baking soda and vinegar solution again to fully clear the clog.
If none of that works then the clog is more severe and likely needs a toilet snake or the clog could be further down the drain.
