Dishwasher rinse aids work great, but they're pricey and loaded with chemicals you just might not want in your home. Why not make your own homemade dishwasher rinse aid instead? Your dishes, your wallet, and the environment will thank you!
I've got three totally natural recipes for you to try, plus I also share what you want to avoid. Not all recipes for DIY rinse aids are safe!
In an effort to reduce the toxins in our home and environment, I've been making homemade cleaning products for some time.
Some I've made because I just wanted to, but some I've made out of sheer necessity. This time it was a case of the latter.
Dirty Dishes in New Dishwasher
When we had to get a new dishwasher, I chose a really good model (on sale of course) and thought we'd have fabulously clean dishes as a result. Instead, I found myself having to clean at least 1/4 of the top rack every single load. Ugh.
Washing dishes by hand after they've gone through the dishwasher cycle is for sure not efficient and not what this already-too-busy-mom needs at the end of the day. Something had to change.
I called the dishwasher manufacturer and they sent me a few samples of dishwasher rinse aid saying that that would help, plus they recommended a specific and very expensive type of detergent.
Well, the detergent I was open to trying, but this frugal-minded mom was determined not to spend even more money and put even more toxic chemicals into our home and the environment.
So off to figure out how to make an all-natural homemade dishwasher rinse aid, I went.
I read somewhere that putting straight vinegar in the rinse aid compartment was a quick and easy DIY Jet Dry alternative.
So I tried it and it worked.
However, soon after making this “genius” discovery, a dishwasher repairman warned me that the acid could possibly eat away at the seals of the compartment. Yikes!
Instead, he recommended the first super simple homemade dishwasher rinse aid that I am sharing with you here.
WARNINGS ABOUT DIY RINSE AIDS
Before we get to the recipes, however, there are some important things you should know about other homemade rinse aids on the internet. Some are quite dangerous.
Don't Mix Acids with Peroxide
There are some recipes online for DIY Rinse Aid made by combining citric acid with peroxide. This is NOT a good idea.
Also, don't mix peroxide with vinegar. Or with any acid. Mixing peroxide with acid makes a super strong oxidizer that can etch metal.
Be Careful with Essential Oils
Essential oils don't mix with water. So if you put essential oils in with peroxide or with water and citric acid, the oils will sit on top and likely will end up creating gummy residue in your machine that might cause a problem.
Don't Use Rubbing Alcohol
There are also some DIY Rinse Aids that recommend using rubbing alcohol as an ingredient. This might ruin your dishwasher that I know of, but it's pretty noxious and rubbing alcohol's fumes are flammable and should be kept from any heat source.
I don't think that the dishwasher's heat source would necessarily be a problem, but better to be safe than sorry and I think the fumes would get pretty intense. Since rubbing alcohol's fumes aren't considered the best to be exposed to, let's just not do this.
3 DIY DISHWASHER RINSE AIDS
Now here are the 3 Easiest Rinse Aids you can make. So easy, you'll never go back to buying it again!
Vinegar Dishwasher Rinse Agent
- Place a small cup in your dishwasher's top rack.
- Fill said cup with a 1/4 – 1/2 cup of white vinegar.
- Run dishwasher as usual.
I mean, who can beat saving tons of money, doing it naturally, and not mucking up the environment with all of those chemicals and extra packaging?
Here's a photo of our dishwasher. The vinegar is in the little plastic container on the lower left. Side note: this is why we have rubber bands on our glasses.
Now, I know it seems crazy, but this really does work. You'd think that the action of the dishwasher would cause all of the vinegar to be diluted greatly before it could help, but it didn't.
I'm sure the effectiveness of this method will depend on the position of the dishwasher arms in your dishwasher.
If this doesn't work for you, another option is to pour a 1/4 – 1/2 cup of vinegar in the bottom of the dishwasher when the rinse cycle starts. Of course, you have to keep an eye on the dishwasher while it's running to do that.
So here is that Super Easy Rinse Aid plus two other options that are basically just as simple!
Peroxide Dishwasher Rinsing Agent
- Hydrogen Peroxide
Instructions
Pour some peroxide into your dishwasher's rinse aid dispenser and run the dishwasher as usual.
Genius Tip: Add a few drops of food coloring (natural food coloring is preferred) so you can see how much is left if you have a compartment that holds a lot of rinse aid.
Pitfalls of this method
Peroxide can bleach cloth, so take care to not get it on your clothes or kitchen linens.
Citric Acid Dishwasher Rinse Agent
- 2 Cups Citric Acid
- 5-10 Drops Essential Oils
Instructions
Mix ingredients and store in a jar.
Place one tablespoon of mixture in the rinse aid compartment prior to each load of dishes.
Pitfalls of this method
Citric Acid can get clumpy if you live in a humid environment. If this happens, you can place a tablespoon or so of bentonite clay in a baby sock or small cloth/rag, seal it with a rubber band, and keep it in the jar with your citric acid blend to absorb moisture.

Citric Acid Dishwasher Rinse Aid
- Combine the citric acid and essential oils (if using) and store in a jar. Place one tablespoon in your rinse aid compartment before running a load of dishes in the dishwasher.
- You can also blend the citric acid with water and then add that to the rinse aid compartment, if you like, but it's really an extra unnecessary step.
Notes
Problems With the Peroxide Dishwasher Rinse Aid Method.
Peroxide can bleach clothing so take care to not get this on your clothing. NOTE: Some recipes online recommend mixing peroxide with citric acid. Do NOT do that. Also, don't mix peroxide with vinegar. Or with any acid. Mixing peroxide with acid makes a super strong oxidizer that can etch metal.Problems With Citric Acid Dishwasher Rinse Aid Method.
Citric Acid can get clumpy if you live in a humid environment. If this happens, you can place bentonite clay in a baby sock or small cloth, seal it with a rubber band, and keep it in the jar with your citric acid blend to absorb moisture.How to Clean Your Dishwasher
To help your dishwasher rinse aid work even better, try these tips.
If you have particularly hard water, try running your dishwasher with vinegar or citric acid every so often or even once weekly to clean it. Simply put 1 cup of vinegar or 1/4 to 1/2 cup of citric acid, or 1 cup of lemon juice either in the bottom of the dishwasher or in a container of the center rack before running it.
With these tips and recipes, you'll have your dishwasher running great, spotless glasses and silverware, without breaking the bank or spending a ton of time!
I’ve used this method before and it does work well but then I was told that vinegar can damage the seals. Has this been anyone’s experience?
Hi there – which method? I discussed the seals issue in the post. Thanks for reading!
Thanks, I reread it but I’m still confused. The dishwasher guy said not to put it in the rinse aid compartment but what about the other seals and the hoses etc which I’ve heard can be damaged in the long term if using the plain vinegar method. Do you use a particular type of vinegar? I read that 5% acetic acid was less damaging. Maybe I’ll try one of the other methods…
I know it’s a bit hard to know what to do–my understanding is that the method I recommended works fine b/c the vinegar will be diluted when the machine runs. I use regular vinegar.
Yes, we had a repairman come out to service our dishwasher and he told us not to use vinegar as a regular rinse aid. Once in a while, like once a month was all he said was even advisable. So I’m searching for another rinse aid recipe. Vinegar does it’s job but it’s very hard on the dishwasher. Being that it would benefit the dishwasher repairman, I felt his advice was sound. He could’ve said, sure go ahead… but he didn’t. He also advised against commercial products due to the chemicals, which I also appreciated. So I’m going to try other recipes. I am running my dishwasher daily…with a large family an all. Bummed about the vinegar. I use it for a fabric softener in my washer and that service repairman seemed to like the idea. So vinegar is great for some things but not everything.
Yes, that’s a puzzle. I don’t know why it is ok (maybe) for some things but not for others….and also why it would be the case that it’s OK for a washing machine. I wonder what the difference could be? The section that you are putting it in, perhaps?
(Note – this comment was edited after the following reader clarified the comment that I misunderstood.)
I don’t think she meant putting fabric softener in the dishwasher; I think she meant she uses vinegar as a fabric softener in the clothes washer and that her repairman didn’t see any harm in that to her washing machine.
Oops makes sense, LOL! I’ll go back and change my reply. Maybe I read her comment too fast and missed that it likely meant that. Thanks!
So great! I do stuff like that…anyway, you can remove my comments if you want, no problem! 🙂 (Now my first doesn’t exactly make sense anyway!) Thank you for your post by the way! I’m glad to have the warning about vinegar!
Thanks much – I left it and edited mine. You are so welcome. It’s such a confusing topic when we hear different things from different people!
I tried the white vinegar method and it worked really well!!
Oh that’s great! In the cup, I assume :)?
Yes in the cup. Easy, cheap and works. How can you beat that? 🙂
No kidding!!! I love it! So glad it worked well for you!
Good tip. My turn.
You cannot save 5800% on dishwashing detergent, or, anything.
All you could save is 100% (if it was free.) You CAN say that Jet Dry is 5800% MORE EXPENSIVE, but you cannot SAVE 5800 %
Hope you can adjust your article. Keep up the work.
Cheers

Hi there. You are totally right! Changing right now. Thanks so much for reading…..I wrote this forever ago, btw. Not an excuse, b/c I make all kinds of mistakes even now….but wow that whole post needs so much updating. Hopefully soon. Thanks again!
I used to put vinegar in the washing machine, to remove chemicals from new cloths. It ended up making my machine rust. I would love to try the vinegar in the dishwasher, but the dishwasher is new and I really want to ruin it.
I know – it’s all so confusing to me!! Some say it’s a problem and others say no and even the manufacturers say to use citric acid to clean the dishwasher!!!
I think the theory is if you put vinegar IN the rinse aid portion of the dishwasher, it will destroy that compartment. that’s why it’s recommended to put it in the top rack in a cup or glass.
Yes, it’s been complicated for sure as you can see in the comments area!
I read that vinegar is too acidic to put in the dispenser as it destroys the rubber gasket/seal.
Hi there.
Yes, I heard that as well but then a number of people commented on this and the follow up post and they had different information. Let me know what you think after reading them :).
I did a bit of research, trying to find the MSDS that I read which indicated that some major rinse aid variant has a pH of 2.2 and I am unable to find it. However, I did find a Proctor & Gamble patent which states and I quote:
“…The rinse aid dispersion has a pH in a range of from 2 to 6…”
So, apparently, that is the range of pH for currently marketed rinse aids. Perhaps, there are several versions of some of them, with different power factors. Vinegar, of course, falls well within that range, clocking in at about 2.5 pH, so it will not harm anyone’s machine. But, think about the lost profits for P&G and the others that are making big bucks from selling rinse aids, if everyone started to use vinegar…
Keep up the good work.
Thank you! That’s a pretty large range….I find that to be odd. However interesting.
I got the pH of 2.2 from a material safety sheet I read some time ago. I think it was Jet Dry, but it might have been another big time rinse aid, like Finish.
Got it – thanks! If you end up looking that up and could come back w/ the information that would be fantastic.
Thanks so much for sharing!
Thank you for reading and you are welcome!
My manufacturer told me that Vinergar can harm my dishwasher .
I know – I have heard this but others have commented that it’s not the case. Please read the comments and let me know what you think!
a repairman that was at my house told me to run my empty dishwasher with a cup of vinegar in the top rack every so often once a week at least, said it helps keep the dishwasher and the lines clean and unclogged…pretty sure it must be safe as a rinse aid…
Sounds like he thinks so at least!
