“These dishes room not obtaining clean!” Amanda yelled.

You are watching: Can you use clr in a dishwasher

I checked out the kitchen to see what the trouble was.

“Look at these bowls!” Amanda said.

I looked at the bowls that had actually just come out of the dishwasher and also they still had actually soup residue approximately the rim.

I then checked the dishwasher filter and I to be shocked!

The filter was totally clogged up v some sort of white residue!

Why go This Happen?

I think this happened for two major reasons:

We have been utilizing generic gelatin dishwashing detergent.

This problem captured me off-guard because I have checked the filters number of times before and they constantly looked clean. Because the filters never ever seemed to acquire dirty, I just forgot around checking them.

This is exactly how our top dishwasher filter looked. That was totally clogged v detergent and also limescale residue. (click come enlarge)

I don’t understand what changed that made the filter clog up choose it did. I suspect that one of the brand of gelatin detergent we used is come blame. We have been using number of brands and also I don’t understand which one is responsible.

I don’t favor gel dishwashing detergent, yet we startedusing it together a convenience for Amanda. She has actually a TBI (traumatic mind injury) that affects she coordination. She was having actually trouble pouring the exactly amount of flour detergent right into the laundry detergent dispenser receptacle on the dishwasher. She would overfill it and also then the small lid ~ above the receptacle would certainly not close. We switched to the gel so if she walk overfill the receptacle, she could still nearby the tiny lid.

Why Was ns Not making use of A Dishwasher Cleaner?

I have actually been making use of dishwashers for decades and have never had actually a difficulty with limescale buildup or laundry detergent residue in adishwasher. So ns didn’t think I needed to use a dishwasher clean product.

NowI am having actually a problem.

I guess the dishwasher detergents are simply not what they supplied to be. The detergent formulas have actually been adjusted due to environmental laws and regulations and also that is something we will have to accept. I guess even old-timers like me will need to start utilizing a dishwasher cleaning product.

I am additionally going come switch ago to a powder or tablet dishwasher detergent. I have actually looked at numerous dishwasher manuals from different manufacturers and also they all recommend making use of powder, tablets, or the dishwasher packs. I have actually an idea the will assist Amanda usage the powder detergent. I hope to expose that idea soon.

Why You have to Clean her Dishwasher

You should clean the dishwasher and dishwasher filters on a continual basis to keep optimum performance of the dishwasher. If the filters become clogged, climate the water doesn’tcirculate like it should. As soon as the water doesn’t circulate like it should, her dishes don’t get clean.

The top filter assembly has actually a good mesh filter the keeps tiny particles the end of the pump. The material is so fine the at a street it looks choose sheer nylon fabric. This cloth can end up being clogged v gummy laundry detergent residue. Once it becomes clogged, it can be daunting to clean the gummy residue the end of the mesh.

Another concern that a dirty dishwasher causes is film top top the dishes. When the within surfaces the the dishwasher space coated through detergent residue, some of that residue will certainly mix in with the wash water and also end up on her dishes.

Residue buildup and rust stains in the dishwasher.
The filter screen on the top filter has tiny holes that easily come to be clogged.

How come Clean her Dishwasher

There room two general ways come clean a dishwasher:

Wait till the dishwasher stops working properly and then do a dishwasher deep-cleaning.

Obviously, the very first option is the preferred method.

How To do The Once-A-Month maintenance Cleaning (Preferred Method)

Citric-Acid MethodTake out the filters and rinse them turn off in the sink. Reinstall the filters.Run an north dishwasher cycle through a citric-acid based dishwasher cleaner. Usage per the parcel instructions.

I recommendFinish Dual-Action Dishwasher Cleaner. This product has a bis-phosphonic mountain salt that works in conjunction with citric mountain to remove scale and also deposits. The is why it is referred to as Dual-Action.

Vinegar Method

Some human being have success doing a maintain cleaning v white vinegar. You could use Heinz cleaning Vinegar if you need extra strength.

What most dishwasher manufacturers recommend is putting 2 cup of vinegar in a measuring cup and placing that on the bottom rack. Then you run the empty dishwasher ~ above a regular cycle.

I ran across a very important guideline while readingLG Dishwasher clean Tips. Below is the pointer in my own words:

Do not pour her vinegar straight into the dishwasher tub. The dishwasher will certainly extract at the beginning of the cycle and your vinegar will go down the drain. Instead, ar the vinegar in a measure up cup on the bottom rack. As soon as the bike starts, the cup will certainly overflow and also the vinegar will certainly mix in with the wash water.

How come Deep-Clean a really Dirty Dishwasher

If the dishwasher is really dirty you might need to use this method.For dishwasher deep-cleaning we will certainly be using CLR Calcium, Lime & Rust Remover.This product is plenty of times much more effective than vinegar because that dissolving calcium and rust.

Based ~ above a pH comparison and the mountain concentration the CLR vs vinegar, I estimate that pure CLR is about 15 times an ext effective at dissolving calcium than family vinegar. In various other words, 1 cup the pure CLR is as effective as a whole gallon of vinegar.

The brand recommends the you wear gloves once using the product. If you acquire it on your skin the will reason irritation and also you must rinse it off under running water every the brand instructions. Please check out the safety-precautions top top the label before use.

Cleaning Steps1 – Door Gasket

The very first thing we want to do is to clean the dishwasher door-seal gasket.For this I blended up 2tablespoon that CLR with 2tablespoon that water to make a 50/50 mix.

Dip a toothbrush in this mix and also scrub the buildup turn off the door gasket. Do not gain it on your countertop or her tile floor. You may want to put down one old towel come catch any drips.

Immediately ~ cleaning, wipe off the gasket v a damp sponge. Go over the a couple of times, rinsing the sponge as you go, to make certain the acid is gone.

Brush the residue off the dishwasher seal through a toothbrush dipped in the 50/50 CLR solution.
After brushing, wipe turn off the seal v a damp sponge. Go over the a couple of times to ensure the mountain is gone.
2 –Filters

Now us will eliminate the upper filter assembly and the lower filter. You have to twist the top filter to eliminate it. The flat lower filter should simply pull out.

To eliminate the top filter you twist it and then lift the out.
The lower filter just pulls out.
4 –Rust Stains & laundry detergent Dispenser

The following thing we will perform is to clean any kind of tough rust stains and likewise clean the laundry detergent dispenser.

I had actually some rust stains in my dishwasher indigenous a rusty baking pan the dripped. The toothbrush was a tiny too tiny and soft, therefore I supplied a food brush v the same 50/50 CLR mixture. The rust stains came ideal off. You have the right to use the CLR full-strength if you have actually some stubborn rust stains.

Next, clean the detergent dispenser gasket and also tray through your toothbrush and the 50/50 CLR. The reason you desire to save this step for last is so girlfriend don’t have to rinse the acid off the tiny dispenser gasket. Friend are around to operation a wash cycle and the gasket will gain rinsed in the wash.

5 – Dishwasher clean Cycle

Now the the hand-operated cleaning measures are done, you will certainly run a dishwasher cycle to finish the clean process.

If girlfriend look about on the internet, you will certainly run throughout a few different ways to go about this. Right here are some examples:

We know that part dishwashers extract immediately after the cycle starts. I understand that mine does since I have the right to hear the water going down the sink drain right ~ the bike starts. This means it may not be a an excellent idea to pour the CLR straight in the bottom. Ns think the critical example above is the correct way. This method your CLR doesn’t get flushed down the drain.

What I decided to do is to usage the old trick of putting a container in the bottom rack. I took a 1-cup measure up cup and also filled that half full v pure CLR. Ns then put this on the bottom rack as shown.

The reason I chose the bottom rack is because my peak spray eight is in the middle. I want the CLR come overflow and also if I put it on the peak rack, then there might not be sufficient spray to make it overflow quickly.

Do no use any kind of detergent during this step and make certain there space no bowl in the dishwasher.

Run a common cycle using warm water or the high-temperature setting if you have it. When that bike finishes, remove the measuring cup and also run one more cycle to rinse out the CLR.


The CLR go a pretty an excellent job. It will certainly not gain out every traces of buildup yet it it s okay a most it. The dishwasher internal looks a lot much better than the did.


Now the we have actually have performed the deep-cleaning, we deserve to maintain the dishwasher by act the monthly maintenance cleanings. The monthly cleaning will remove any kind of remaining residue and aid keep the filter from becoming clogged with detergent residue.

Happy Cleaning!

Though you’d mentioned having actually a equipment in mind for overcoming Amanda’s concern with dispensing the exactly amount of powdered detergent, how about a pretty basic solution such as transferring the powder right into a bucket v a lid instead? (or a big coffee can, the north container from dishwasher laundry detergent pods, etc.)

Then just keep a tiny plastic scoop in that that’s the ideal amount to fill the dispenser…? many of store-bought items this days come with small scoops included which, in most people’s cases, for sure often finish up just being recycle or thrown in the rubbish after stated product is finished… so surely it have to be easy enough to scrounge increase a suitable container & scoop and also may already have those kicking about your house begging because that a purpose!

(Incidentally, one together scoop the the best size which instantly comes come mind is the one the comes in a container that Oxi-Clean, i beg your pardon would likewise be good to incorporate right into your dishwasher clean routine! Or far better yet, you can gain the cheaper knock-off variation from dollar Tree which is every bit as an excellent & effective as the brand name version)

Anyways, perhaps that’d be an easy & practical solution because that her?? hope it helps!
