The Optimist Cleaning Kit

April 6, 2015(updated on February 3, 2023)

Homemade cleaning products can be inexpensive and effective. The Optimist isn’t in business anymore, but their formulas are still great.

The Optimist kit front

For the last decade, I’ve kept an ugly, industrial-looking spray bottle of diluted white vinegar under my sink. I use it mostly as a simple, non-toxic countertop spray that’s good for quick clean-ups during meal prep. While it’s been effective enough, both the look of the spray bottle and the unadulterated scent of vinegar leave something to be desired.

The Optimist kit back

Enter The Optimist Co. Founded by Devin Donaldson after conventional cleaning products left her with a nasty asthma attack, they focus on simple, effective, non-toxic cleaning products that will help you keep your home spotless without compromising your health or the planet.

Devin sent me The Optimist Co.’s Make Your Own Cleaning Products Kit to try out a few weeks back. It comes with two amber-colored spray bottles with the cleaning formulas printed on the labels, a small bottle of castile soap and three small bottles of essential oils to make your custom scents.

Add some white vinegar and flat club soda* from your pantry to the mix and you have everything you need to build both an all-purpose spray (Time to Shine) and a glass and surface cleaner (Bright Side).

Making The Optimist Bright Side cleaner

I made up both bottles the same day that the kit arrived. I followed the suggested recipes almost exactly, making only one change to the Bright Side. It suggests that you use plain white vinegar but instead, I used some of the lemon-infused vinegar I’d made during my Meyer lemon frenzy back in January (that’s what’s in the smaller measuring cup in the picture above). Bolstered with the enclosed lemon essential oil, every spray of that cleanser is an olfactory pleasure.

I’ve been using these sprays exclusively since they arrived and could not be more pleased with their effectiveness. I use them without worry around food, because I know that if a few droplets land on the contents of the fruit basket, no one will be harmed. Plus, they are far prettier than my old bottle of watered down vinegar.

The Optimist Bright Side

*When we talked, I asked Devin what the flat club soda added to the mix and she said that it helps the cleaner wipe away streak-free, particularly on stainless steel appliances. So clever!

  • Vinegar and baking soda and a bit of essential oils in different combos will take care of most cleaning needs.

  • I like using powdered Borax for cleaning toilets. Sprinkle in a generous amount, in water and on wet porcelain, let sit then scrub.

  • I use just a slightly damp microfiber towel for most of my dusting – no need for the aerosol sprays. Also use white vinegar in the softener dispenser of my washing machine and dryer balls in the dryer; haven’t used fabric softener or dryer sheets in over 15 years!

  • I can’t really say what I’ve done specifically.

    I use a broom outside instead of water.

    I used to use a concentrate and mix my own cleaning solution but they discontinued that.

    I did make my own insect spray once but didn’t have regular vinegar so used some old balsamic vinegar that was way expired. That was pretty much of a disaster as I had to wash down all of the walls and cabinets; wherever the spray hit there was a brown spot or drips from the vinegar.

    I do use baking soda and lemon for cleaning pots and pans.

    I scrub classes with salt.

    I’ve switched to cloth tea towels in the kitchen and will be crocheting my own dishclothes starting this summer. Don’t have the time right now.

    I’ve also become pretty good at pretreating clothes with baking soda and peroxide.

  • I have the same vinegar bottle. My husband hates the smell. I also try to clean up messes with clothes instead of paper towels.

  • I don’t buy paper towels, and I try to use all-natural soaps and detergents. I also limit showers to once every two days (when reasonable) and only do laundry if I can wash a full load.

  • Does not cleaning count? 😉 I’m sort of kidding! When I do get around to it, I’m using “rags” as my grandma calls them. That is t-shirts, etc that would otherwise be tossed because they’re too holey or stained.

  • I use diluted Vodka, a spray bottle under each sink. I took a spray bottle to Mexico and generously sprayed our toothbrushes, the sink, fixtures, toilet, etc. and in three weeks didn’t get sick at all. I believe it is stronger than vinegar and has no odor.

  • We recently had a(smallish) kitchen fire, everything I read about soot & extinguisher clean up required the use of more chemicals. I ended up using rubbing alcohol & soft old t-shirt, it worked fabulously and I didn’t have to use expensive harmful chems!

  • Instead of commercial cleaner, I keep a spray bottle of bleach water under the kitchen counter. I don’t remember the proportions because I don’t have to; I wrote them in Sharpie on the bottle.

  • I ditched the paper towels! Reusable cloth towels have saved my family hundreds and saved the environment.

  • mine is not currently sustainable. I’ve been doing research on natural cleaning supplies, and something like this would be amazing to help me get started!

  • The greenest thing I do is clean less! 🙂

    In all seriousness… We’ve switched to using as little paper products as possible by using washable rags for cleanup. I made the switch to more eco-friendly cleaners years ago, but now I’m moving towards more of my own homemade products. I’ve greened my clothes washing routined with homemade detergent, white vinegar for fabric softener, and wool felt dryer balls. Thanks for the chance to win. Those look like great products!

  • I use cloth towels for minor clean-up, and semi-reuseable towels for bigger messes (reuse them a few times before tossing- a little better than paper towels, at least!)

  • Letting water work. For example, spraying water on a counter and letting it stay the for a minute before wipping gives it a change to work.

  • I’ve been making my own laundry soap powder! I’ve grabbed an old food processor and dedicated it to the task of shredding/blending my soap mix.

  • I make my own laundry detergent from leftover odds and ends from my homemade soap–I started doing this as a poor grad student 6 or 7 years ago and have never looked back. Other than buying Bon Ami (which I LOVE) to scrub sinks, I make all of my other cleaning products from the “essentials” I keep beneath my kitchen sink: baking soda, vinegar (white or infused), castille soap, and essential oils. I, too, have long loathed the drab look of my homemade goods, so I’m excited to hear about the Optimist (and that club soda tip)!

  • I use ecloths to wipe down my bathroom countertops. It’s easier since I keep the cloth in the bathroom and don’t have to run around finding the right cleaner. And I love not using a cleaner all the time.

  • I try to avoid putting things off. If I rinse my dish right after dinner, put it in the dishwasher immediately, it’s more likely all other dishes will follow and be done in a reasonable time. If I tell myself I’ll put it off until tomorrow, it will never get done until it is overwhelming.

  • i use ‘unpaper’ towels for spills and wiping the counter down. Reusable sponges and microfiber cloths are great for dishes. This set is great.

  • We use microfibre cloths to clean mirrors. If anything is a bit stubborn then I lightly wet one cloth, use it, and then use the dry one to finish it off. It is easy and requires no cleaning product whatsoever.

  • We started using cloth napkins and love them. Can re-use for several meals and pop in the washer. Also use micro cloths for cleaning instead of too many paper towels! They really work well and again are easy to wash.

  • My girls and I do our chores at the same time, all together. It gives our Saturday mornings a rhythm and I find that end up working much harder knowing they are doing their (very simple) chores at the same time.

  • The biggest thing I’ve done lately has been to use my flour-sack towels for all the wipe-ups and general cleaning. I also got a bunch more of them so I never have all of them dirty and go back to the paper towels.

  • Do less cleaning? 😉 Actually, I use a lot of white vinegar and essential oils for my cleaning supplies.

  • I’ve been diluting Dr. Bronner’s castille soap to use as a spray cleaner, sometimes with a squirt of white vinegar. I also use baking soda to scrub my sinks… I recently squeezed some lemons and used the rinds as scrubbies after sprinkling baking soda in my sink. Worked great and smelled heavenly! I’d love to give this kit a try… I think it’d take me to the next level!

  • I emphasize use of rags over paper towels in our house, clean up spills with plain water as quickly as possible after I notice them, and add vinegar when I need something “stronger”

  • I’ve been using nontoxic cleaner and a serious scrub brush to clean my bathtub, which gets grimy pretty quickly from hard water plus castile soap!

  • I cut up and hemmed several flour sack towels into dishrag size, and keep them in a basket on the counter to use instead of paper towels.

  • I use baking soda instead of Comet to clean tubs and sinks! I also use diluted vinegar as an all purpose counter spray.

  • This kit looks great! I just bought a big stack of microfiber rags and have been using baking soda and vinegar to keep my drains clear. Cheaper and works better than draino!

  • I make my own laundry soap and it only costs a couple of dollars per YEAR, and this morning I tried out a new dishwasher gel made with lemons (free, from a neighbor’s tree), vinegar, and salt. I’ve been trying out several “recipes”for the dishwasher to find one I really like. I use baking soda instead of scouring powder. I use cloth napkins. I make my own orange cleaner from peels and vinegar and love it on my wood cutting board! I make my own citrus extracts as well as vanilla. I have access to citrus trees, and made orange, grapefruit, and lemon extract, plus triple sec and Grand Marnier, and brandied vanilla extract that is pure heaven in a cup of coffee! I have some of the triple sec sitting in a small glass container in bathroom window right now, covered lightly, which will become orange oil when the alcohol evaporates. It was a bumper citrus year for us! I’d LOVE to try out this kit, and I also want to make cleaner with Tea Tree oil to discourage mold in this humid environment! I am SOLD on kitchen chemistry!

  • Been making my own detergent and using straight white vinegar for fabric softener for quite a while.

  • I mostly use castille soap, baking soda, and white vinegar for my cleaning needs, but I would love to try making my own glass cleaner! What a fun looking kit.

  • I don’t use paper towels or cleaning wipes at all. I even mop with a reusable pad, and not the Swiffer pads.

  • I do the vinegar water in a bottle too. I also use holey socks, old ratty towels, old holey t-shirts and such for cleaning. We have microfibers which I love, but the other things I consider disposable. I use and wash for most things, but if it is a nasty mess then we can use and toss without guilt since they would have been tossed previously. This kit sounds like a brilliant all in one item for those of us who like to keep it natural!

  • I’ve been doing research about how I can make my own cleaners and even repurposed a Bulleit Rye bottle as a snazzy looking dish soap bottle.

  • I am conscious about what products I use and keep them as green as possible. I also use reusable cloths as much as possible.
