Frequently Asked Questions

How Often Should I Replace My Home Cleaning Products?

While all of the home cleaning products we produce are made from plant-based ingredients- nearly all of them have a shelf life of just over three years. Our products are made to last and stay effective and smelling great- so you don’t have to worry about constantly buying more. If you do end up using them all- and loving them- we highly recommend trying out our refill concentrates for the second time around. Save the plastic bottles from your first purchase (trust us, they’re sturdy) and add water to the concentrated formula. You’ll be saving the environment and a fair chunk of change.

What are The Most Common Ingredients in Sustainable Home Cleaning?

While each of our products have a specific formula designed The most common ingredient in Murchison-Hume cleaning products is Decyl Glucoside. This compound is completely derived from plants and is so mild that it’s commonly used in baby shampoo and personal care products for those with sensitive skin. While we hate to give away our secrets, we found out that it’s also quite the effective surface cleaner and doesn’t muck up surfaces. It’s also completely biodegradable so it’s good for both you and the planet. 

What Are The Most Important Ingredients To Avoid In Home Cleaners?

While there are almost too many creepy chemicals to count (much less try and pronounce), the big ones we try to avoid are bleach, ammonia, potassium hydroxide and sodium hydroxide. These chemicals are not only quite caustic, but you need to be extra careful about what you mix them with: you don’t want to accidentally create a cloud of noxious fumes. Unfortunately, this stuff is found in your everyday grocery store cleaners like Lysol and Clorox, which is why we do what we do.

What Is The Best Natural Cleaning Spray For Bathtubs?

We recommend our all natural Bathroom Cleaner, which comes in a spray bottle, as well as a concentrated formula if you prefer to use your own container and help reduce plastic use.

Our All-Purpose Cleaner is the ideal sidearm to start tackling a messy kitchen. It works great on all types of surfaces including countertops, stainless steel, and more.

Are Natural Fragrances Important In Cleaning Spray?

Natural cleaning sprays walk a fine line between being tough on dirt and grime, but gentle enough for the human body. While some natural fragrances work great with a sustainable cleaning formula, there are plenty of synthetic fragrances that are perfectly healthy to be around and smell incredible as well.

Can I Make Natural Cleaning Products At Home? How To Make Natural Cleaning Products?

Some swear by the classic combination of vinegar and baking soda, and while we love the enginuity, there’s one thing we just cannot live with- the lingering smell of vinegar all over our kitchens. Let’s save the vinegar for the salad dressing and your mother’s favorite baked chicken recipe. Cleaning products shouldn’t bring down the fragrance of your home, they should elevate it. We’re absolutely obsessed with our Original Fig and Australian White Grapefruit Scents, they have become a staple in our home fragrance lineup.
