“These dishes are not getting clean!” Amanda yelled.

You are watching: Can i use clr in my dishwasher

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

“Look at this bowls!” Amanda said.

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

I then confirm the dishwasher filter and also I was shocked!

The filter was fully clogged up with some type of white residue!

Why did This Happen?

I believe this taken place for two major reasons:

We have been using generic gelatin dishwashing detergent.

This problem caught me off-guard since I have actually checked the filters number of times before and they constantly looked clean. Because the filters never seemed to obtain dirty, I just forgot about checking them.

This is just how our upper dishwasher filter looked. That was fully clogged through detergent and limescale residue. (click come enlarge)

I don’t know what adjusted that do the filter clog up favor it did. I doubt that among the brands of gel detergent we provided is come blame. We have been using number of brands and also I don’t know which one is responsible.

I don’t like gel dishwashing detergent, but we startedusing it together a convenience for Amanda. She has actually a TBI (traumatic mind injury) the affects her coordination. She was having actually trouble pouring the exactly amount of powder detergent right into the detergent dispenser receptacle top top the dishwasher. She would overfill it and then the tiny lid ~ above the receptacle would certainly not close. Us switched to the gel so if she go overfill the receptacle, she could still nearby the small lid.

Why Was i Not making use of A Dishwasher Cleaner?

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

NowI am having actually a problem.

I assumption: v the dishwasher detergents are simply not what they supplied to be. The detergent formulas have been readjusted due to eco-friendly laws and regulations and that is something us will have to accept. I guess also old-timers prefer me will have to start making use of a dishwasher cleaning product.

I am additionally going come switch earlier to a powder or tablet dishwasher detergent. I have looked at numerous dishwasher manuals from various manufacturers and they every recommend making use of powder, tablets, or the dishwasher packs. I have an idea the will help Amanda usage the powder detergent. Ns hope to reveal that idea soon.

Why You should Clean your Dishwasher

You must clean the dishwasher and also dishwasher filters on a continuous basis to preserve optimum power of the dishwasher. If the filters come to be clogged, climate the water doesn’tcirculate favor it should. Once the water doesn’t circulate choose it should, her dishes don’t get clean.

The top filter assembly has a fine mesh filter the keeps tiny particles the end of the pump. The material is so fine that at a street it looks like sheer nylon fabric. This cloth can end up being clogged through gummy detergent residue. When it becomes clogged, it deserve to be complicated to clean the gummy residue out of the mesh.

Another concern that a dirty dishwasher reasons is film top top the dishes. Once the inside surfaces the the dishwasher room coated with detergent residue, some of that residue will mix in with the wash water and end increase on your dishes.

Residue buildup and rust stains in the dishwasher.
The filter display screen on the top filter has actually tiny holes that easily end up being clogged.

How to Clean her Dishwasher

There room two basic ways come clean a dishwasher:

Wait until the dishwasher fails properly and then do a dishwasher deep-cleaning.

Obviously, the first option is the preferred method.

How To perform The Once-A-Month maintain Cleaning (Preferred Method)

Citric-Acid MethodTake the end the filters and also rinse them off in the sink. Reinstall the filters.Run an empty dishwasher cycle v a citric-acid based dishwasher cleaner. Use per the parcel instructions.

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

Vinegar Method

Some civilization have success doing a maintain cleaning through white vinegar. You might use Heinz clean Vinegar if you require extra strength.

What most dishwasher manufacturers recommend is placing 2 cup of vinegar in a measure up cup and placing that on the bottom rack. Climate you run the north dishwasher ~ above a common cycle.

I ran throughout a very important tip while readingLG Dishwasher cleaning Tips. Here is the guideline in my own words:

Do not pour your vinegar straight into the dishwasher tub. The dishwasher will certainly extract at the start of the cycle and your vinegar will go down the drain. Instead, place 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 through the wash water.

How come Deep-Clean a very Dirty Dishwasher

If the dishwasher is an extremely dirty you may need to use this method.For dishwasher deep-cleaning we will be making use of CLR Calcium, Lime & Rust Remover.This product is countless times much more effective than vinegar for dissolving calcium and also rust.

Based top top a pH comparison and the acid concentration of CLR vs vinegar, I estimate that pure CLR is around 15 times more effective at dissolving calcium than family vinegar. In various other words, 1 cup the pure CLR is as reliable as a totality gallon the vinegar.

The label recommends the you undertake gloves when using the product. If you obtain it on her skin it will cause irritation and you need to rinse it off under running water per the label instructions. Please check out the safety-precautions top top the label prior to use.

Cleaning Steps1 – Door Gasket

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

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

Immediately after cleaning, wipe turn off the gasket v a damp sponge. Walk over it 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 with a damp sponge. Go over that a few times come ensure the acid is gone.
2 –Filters

Now we will remove the top filter assembly and the lower filter. You have to twist the top filter to eliminate it. The level lower filter should simply pull out.

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

The next thing us will do is come clean any kind of tough rust stains and also clean the laundry detergent dispenser.

I had actually some rust stains in my dishwasher native a rusty baking pan that dripped. The toothbrush was a tiny too tiny and soft, so I provided a food brush with the exact same 50/50 CLR mixture. The rust stains came appropriate off. You deserve to use the CLR full-strength if you have actually some stubborn rust stains.

Next, clean the laundry detergent dispenser gasket and also tray v your toothbrush and the 50/50 CLR. The reason you desire to conserve this action for critical is so you don’t need to rinse the acid off the small dispenser gasket. Girlfriend are about to run a to wash cycle and also the gasket will obtain rinsed in the wash.

5 – Dishwasher cleaning Cycle

Now that the hand-operated cleaning procedures are done, you will certainly run a dishwasher bike to end up the cleaning process.

If you look around on the internet, you will certainly run throughout a few different means to go around this. Below are some examples:

We recognize that part dishwashers extract immediately after the bike starts. I know that mine does because I have the right to hear the water going under the sink drain right after the bike starts. This way it might not it is in a an excellent idea to to water the CLR directly in the bottom. Ns think the critical example above is the correct way. This method your CLR doesn’t get purged down the drain.

What I made decision to carry out is to use the old trick of placing a container in the bottom rack. I took a 1-cup measure cup and filled the half full v pure CLR. I then placed this ~ above the bottom rack as shown.

The factor I decided the bottom rack is since my peak spray eight is in the middle. I desire the CLR come overflow and if I placed 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 also make certain there are no bowl in the dishwasher.

Run a typical cycle using hot water or the high-temperature setting if you have it. Once that bicycle finishes, remove the measure up cup and also run another cycle to rinse the end the CLR.


The CLR go a pretty an excellent job. It will not get out every traces of buildup however it it s okay a most it. The dishwasher interior looks a lot far better than it did.


Now that we have actually have perform the deep-cleaning, we have the right to maintain the dishwasher by act the monthly maintenance cleanings. The monthly cleaning will certainly remove any type of remaining residue and assist keep the filter from becoming clogged through detergent residue.

Happy Cleaning!
