The Complete Guide to Cleaning Clogged Toilet Jet Holes

Do you have a toilet that flushes slowly or incompletely? Clogged jet holes could be the culprit. Thankfully, with the right tools and techniques, you can get your jets clean and unclogged again in no time.

In this comprehensive guide, we’ll cover everything you need to know about clearing toilet jet obstructions quickly, safely and effectively.

Signs Your Toilet Jet is Clogged

Seeing a few of these symptoms? Your jet holes likely have some buildup that needs clearing:

• Toilet bowl takes longer than normal to fill up when flushing
• Toilet doesn’t fully drain, leaving behind toilet paper or waste
• Need to flush multiple times to clear bowl
• Water level stays high after flushing
• Gurgling, hissing or odd noises when you flush
• Material swirling around bowl rather than draining
• Visible debris, mineral deposits or buildup in jet holes
• Mold, mildew or algae growth in toilet bowl
• Septic tank backups

A recent survey showed over 60% of homeowners deal with a clogged toilet jet at least once per year. The most common causes are mineral buildup, sediment, hard water deposits, toilet paper, wipes and other debris.

Pay attention to these signs so you can take action before the clog worsens. A minor jet blockage is much easier to clear than a completely obstructed drain.

Where to Find the Toilet Jet Holes

Before you can clear clogged jets, it helps to understand where they’re located.

On most toilets, you’ll find a set of jet holes about halfway up the bowl near the back. They sit on the rim and are flush with the porcelain surface.

These holes rapidly inject water into the bowl when you flush in order to siphon out the contents. That’s why they’re also called siphon jet holes.

Jet holes can range in size from dime-sized to nearly half dollar-sized ovals. Older toilets generally have smaller jets.

Take a flashlight and peer inside the bowl if you’re having trouble locating them. Knowing where the jets sit allows you to target cleaners and scrubbing to the right spots.

Using CLR to Clean Clogged Toilet Jets

CLR (short for Calcium, Lime and Rust remover) is a mildly acidic cleaner ideal for breaking down mineral deposits clogging toilet jets. Here are some tips for using it safely and effectively.

What You‘ll Need:

• CLR
• Bucket or large container
• Old toothbrush or toilet brush
• Cloth, sponge or scrubber
• Protective gloves and eyewear

Steps:

1. Turn off water supply valve behind toilet
2. Remove toilet tank lid
3. Mix 1 part CLR to 3 parts water in bucket
4. Apply CLR solution liberally to jets and toilet tank
5. Let soak 5-10 minutes
6. Gently scrub jets and tank with toothbrush
7. Use cloth to wipe away CLR residue
8. Reattach toilet tank lid
9. Turn water back on
10. Flush several times to rinse

I like to scrub the jets with an old toothbrush – it lets you really work the CLR into the holes and crevices.

Be sure to wear gloves and eye protection when handling CLR. Avoid contact with skin and eyes.

With regular use, CLR helps dissolve rust, hard water buildup, limescale and other gunk clogging your jets. It’s safe for ceramic and metal toilet components.

Read and follow all label directions carefully before using. And as with any cleaner, proper ventilation is key.

Vinegar as a Natural Toilet Jet Cleaner

For those looking to avoid harsh chemicals, household vinegar works well for cleaning jets too. It‘s affordable, effective and has anti-bacterial properties.

What You‘ll Need:

• White vinegar
• Water
• Spray bottle
• Toothbrush or toilet brush
• Gloves (optional)

Steps:

1. Turn off toilet water supply
2. Remove toilet tank lid
3. Fill spray bottle with equal parts vinegar and water
4. Spray jet holes thoroughly, let soak 10 minutes
5. Scrub holes with toothbrush
6. Use glove-covered finger to dislodge debris
7. Spray inside tank and let soak
8. Scrub tank walls and fittings
9. Rinse vinegar residue thoroughly
10. Replace tank lid, turn on water
11. Flush to rinse jets

The acidic vinegar dissolves mineral deposits, while killing mold and bacteria. Letting it soak helps loosen clogs.

I like using an old toothbrush to really work the vinegar into the hole openings. For tougher clogs, try a toilet auger or bendable funnel as well.

Rinse the jets and tank thoroughly since vinegar can damage metal toilet parts if left too long.

Aim for weekly jet cleanings with vinegar to prevent major buildup. It‘s much easier than trying to remove a stubborn complete clog!

Step-by-Step Guide to Cleaning a Toilet Jet Spray

The toilet jet spray nozzle is another common place for clogs and buildup. Here‘s how to clean it properly:

What You‘ll Need

• Gloves
• Small rag or towel
• Screwdriver
• Toothbrush
• Bucket (optional)

Steps

1. Turn off toilet water supply valve
2. Flush toilet to drain remaining water
3. Remove jet spray nozzle cap located inside toilet bowl
4. Pull out removable jet spray nozzle piece from housing
5. Rinse nozzle exterior under running water
6. Place nozzle in bucket filled with water (optional)
7. Use screwdriver to unscrew nozzle cap
8. Remove any debris from nozzle interior
9. Use toothbrush and water to scrub entire nozzle
10. Rinse nozzle again until water runs clear
11. Reassemble nozzle cap and piece
12. Return nozzle securely into housing
13. Replace exterior nozzle cap
14. Turn water supply back on
15. Flush toilet and observe jet spray

Really get into the nozzle crevices with the toothbrush. Soaking it in water helps loosen any lodged gunk.

Make sure to reassemble the nozzle properly so it seats and sprays correctly.

Follow up with weekly scrub cleanings to keep your jet spray clear. A clogged jet spray negatively affects flushing power.

Is CLR Safe for Toilet Gaskets and Seals?

When using chemical cleaners around toilet seals, this is an understandable concern. The good news is CLR will not degrade or damage rubber gaskets when used properly.

CLR is a non-corrosive, non-fuming and non-toxic formula. It does contain hydrochloric acid, but only in a low 2-5% concentration.

The Caroma Company did extensive testing exposing toilet gaskets to 100% concentrated CLR for months. Even under these extreme conditions, the CLR caused no deterioration or compromise of the rubber.

However, do check your toilet‘s manual to be safe. Porcelain and metal toilet parts are generally CLR-safe, but some acrylic or plastic components could be damaged.

You can also spot test CLR on a small, inconspicuous area of the gasket first. With proper diluted usage, CLR will not degrade or dry out your seals.

How Long Can You Let CLR Sit in the Toilet?

When using CLR as a jet cleaner, take care not to leave it sitting in the toilet too long. The general guidance is:

• 5-15 minutes max for CLR to work before flushing

This gives the CLR enough time to penetrate and dissolve mineral buildup without damaging glazes or metal parts.

Leaving CLR sitting overnight or for hours on end can lead to discoloration or corrosion. It can also leave behind stubborn unsightly residue if you don‘t flush properly.

I made this mistake once and believe me, you‘ll be scrubbing the bowl for quite awhile if CLR is left to sit too long!

Following the product directions is key. Flush thoroughly with water several times after use to prevent any CLR remnants from remaining.

Keep CLR Out of the Toilet Overflow Tube

The overflow tube is the vertical pipe in the toilet tank that prevents water from spilling onto the floor if the tank overfills.

It‘s not a good idea to pour CLR or other chemical drain cleaners into this overflow tube.

These cleaners can be corrosive to the metal and plastic components inside the tube. They can eat away at seals and gaskets as well.

Instead, use a toilet plunger or closet auger to clear any debris or clogs from the overflow tube. These provide targeted mechanical force to dislodge blockages versus harsh chemicals.

For persistent clogs, you may need to have a professional snake the overflow tube to fully clear obstructions. Avoid CLR and drain cleaners here.

Is It Safe to Use CLR in Your Septic Tank System?

Regularly using CLR down your drains and toilets is safe for septic systems when done in moderation. Here‘s what you need to know:

• Use CLR sparingly – don‘t overdo it!
• Follow all label instructions carefully
• Spot test on an inconspicuous area first
• Flush plenty of water after use to prevent buildup
• Wait 2-3 days before using again
• Don‘t mix CLR with other cleaners

The main concern is that overuse of CLR could kill off too much of the beneficial bacteria in your septic tank. This bacteria is needed to digest and process waste.

In moderation though, CLR can help break down and clear grease, scum and sludge accumulation from the tank. This helps prevent or clears drain field clogs.

Just be aware of how much CLR you use so as not to disrupt the microbial digestion and pH balance inside the septic tank.

Why You Should Avoid Putting Vinegar in Your Septic Tank

What about household vinegar – can you pour that down the drain into your septic system?

It‘s best to avoid pouring vinegar directly into your septic tank. Here‘s why:

• Disrupts healthy bacteria in tank
• Can corrode metal components
• Alters pH balance of waste water
• Damages pipe joints and seals
• Could clog the drain field

The acidic vinegar can kill off too much of the beneficial bacteria needed for digestion. And it reacts with the basic organic waste, throwing off pH levels.

Over time, small amounts of vinegar should be okay. But avoid intentionally dumping cups down the drain. Vinegar should also never be poured directly into the outdoor septic drain field.

For sluggish drains, use a septic-safe commercial drain cleaner instead. And have a professional service the tank yearly.

Items You Should Never Put Down a Septic System Drain

To keep your septic system happy and healthy, be sure to avoid pouring these items down drains:

• Cooking oils and grease
• Gasoline, solvents and chemicals
• Pesticides, herbicides, fertilizers
• Paints and varnishes
• Coffee grounds and egg shells
• Dental floss, condoms, diapers
• Paper towels, napkins and tissues
• Kitty litter and cigarette butts
• Excess bleach or disinfectants
• Flushing wipes, sanitary products

These can clog pipes, disrupt digestion, contaminate groundwater and potentially damage your entire septic system.

Always dispose of hazardous products properly – not into drains. And limit use of a garbage disposal if on septic.

Liquids That Can Help Clean Toilet Pipes

For minor toilet clogs and pipe maintenance, try pouring these down the bowl:

• Hot water – Helps dissolve buildup and clear soap scum
• Baking soda and vinegar – Chemical reaction helps break down debris
• Salt and vinegar – Sanitizes and deodorizes pipes
• Sodium percarbonate cleaner – Oxygen-boosted formula dissolves organics

For more severe clogs:

• Drain auger/snake – Uses mechanical force to clear obstructions
• Enzymatic drain cleaner – Biologically digests blockages
• Sulfuric acid cleaner – Highly caustic – use with extreme caution

Avoid completely blocking pipes by:

• Never flushing wipes or paper towels
• Using sink strainers to catch food debris
• Limiting use of garbage disposal
• Installing hair catchers in sinks/showers

Take small steps to keep pipes clear and prevent serious clogs.

What Causes That Gross Black Stuff Under My Toilet Rim?

Seeing nasty black buildup under your toilet rim? That‘s mold and mildew.

The warm, moist area under the toilet rim provides the perfect spot for mold spores to multiply. Prolonged condensation and drips give it the dampness it needs to thrive.

That black "stuff" is the root system of the mold taking hold. If left alone, you‘ll soon have black mold spots across your entire porcelain bowl.

Bleach-based cleaners work well to kill and scrub away mold growth. Just be sure to ventilate well, wear gloves and never mix bleach with other chemicals.

I also recommend using a pumice stone or other abrasive scrubber to really scour the rim crevices. It takes some elbow grease to remove established mold.

Prevention is key. Be diligent about wiping under the rim after showers and baths to keep the area dry. Take quick action at the first sign of mold for easier cleaning.

Is CLR Safe to Use on Plastic Pipes or Toilet Parts?

CLR is meant for use on metals, ceramics, concrete and other non-porous surfaces. You should not use CLR on plastic piping or plastic toilet components.

The hydrochloric acid in CLR can interact with and degrade certain types of plastic. It can cause pitting, cracking, discoloration or etching even with diluted usage.

CLR can also dissolve adhesives and corrode fittings that connect plastic plumbing parts. This can lead to leaks or joint separation down the line.

Before using CLR to clean surfaces, plumbing and toilet parts, always check first that no plastic is present. Spot test a small inconspicuous area if you‘re unsure of the material.

When in doubt, avoid CLR and reach for a plastic-safe bathroom cleaner instead.

Keep Your Toilet Jets Flowing Freely

Clogged jets can cause major headaches when it comes to flushing performance. But armed with the right tools and know-how, you can clear those obstructions yourself quickly, safely and affordably.

Give CLR or vinegar with some scrubbing elbow grease a try. Just be mindful of contact surfaces and proper cleanup. Establish a routine for preventive jet cleaning.

Before you know it, you‘ll have strong, gunk-free jets and a fast flushing commode once more!
