The best soap for menstrual cups

asan one-drop cleanser

Have you been using soap on your menstrual cup? Or are you trying to figure out how to clean your menstrual cup?

Then this article has all the information you need about the best soap for menstrual cups!

first things first – what is a menstrual cup and how do you clean it?

A menstrual cup is a reusable period product, usually made from silicone. It is inserted into the vagina and collects your flow.

As it is being reused over and over, it’s super important to know how to keep your menstrual cup clean and sterilised.

There are two simple steps for cleaning a menstrual cup:

  1. Boil the cup between periods to completely sterilise: Let your cup sit in a pot of boiling water for 5-10 minutes to completely sanitise it. This should be done before you first use it, and between periods

  2. Wash with clean water during periods: During your period, wash your cup thoroughly with clean running water each time you take it out and empty it

do I really need to boil the cup between periods?

To completely sterilise your cup and make sure you kill 100% of the bacteria on it, the safest thing to do is to boil your cup between periods. 

Make sure you fill the pot with plenty of water and don’t boil for too long – as the cup can get burnt if all the water evaporates. (Seriously, it’s happened to one many happy Asan cup users who have left their cup boiling for too long!)

We understand that not everyone wants to take their menstrual cup into their kitchen to boil it. If this is the case, we recommend you soak the cup in a mug of recently boiled (i.e. very hot) water. Put a lid over the mug to retain the heat.

can i use regular soap with my menstrual cup?

No, please don’t use regular soap for menstrual cups! This can be harmful in multiple ways and is really not a good idea.

Firstly, regular soap can contain harsh chemicals which can damage the silicone of your menstrual cup. Even if you are using a fragrance-free soap, it can still contain harmful chemicals.

Secondly, using soap for menstrual cups can leave residue on your cup - and these chemicals can irritate the inside of your vagina when you insert the cup. This can upset the delicate pH of your vaginal flora and lead to itching and discomfort.

Asan has developed a special soap for your menstrual cup called OneDrop Cleanser, which is made from natural ingredients (lavender extract) and is formulated by scientists to be gentle on your cup and your body. 

The Asan cleanser is better than soap for cleaning menstrual cups. If you would like a special soap, then we suggest using our cleanser rather than any other cleaning solution.

can i use dish soap on my menstrual cup?

No, absolutely not. Dish soap is full of strong chemicals that will harm the cup’s silicone and your body. Please don’t use dish soap on your menstrual cup.

can i use dettol on my menstrual cup?

Again, the answer is no. Please don’t use dettol soap for your menstrual cup. Although dettol is a disinfectant, it hasn’t been designed to be compatible with silicone, and it certainly was not designed to go anywhere near the inside of your vagina!

Even a small residue of dettol left on the cup can irritate your vagina. If you would like to have a special disinfectant, please use our OneDrop cleanser which will kill 99% of bacteria.

which menstrual cup wash is best?

The best soap for menstrual cups is Asan’s Natural Menstrual Cup wash. Here are a few reasons why:

  1. It was formulated by scientists to be gentle on the cup and your body
  2. It kills 99% of bacteria
  3. It’s made from natural ingredients, including lavender extract
  4. It is an unscented, oil free soap 
  5. It comes in a portable bottle that easily fits in your handbag
  6. It’s a concentrated solution – you only need one drop, which means it will last much longer than regular soap, and is more sustainable!

    how do i wash my menstrual cup with a cleanser?

    This is super simple.

    Just squeeze one drop of Asan’s fragrance-free cleanser into your menstrual cup and dilute it with clean water. Spread the liquid and wash your menstrual cup thoroughly. You can then immediately re-insert it.

    is it compulsory to wash a menstrual cup with soap?

    No, a cleanser on your menstrual cup is optional. It’s perfectly safe to wash your cup thoroughly with clean running water – and this is definitely preferable to commercial soaps that can harm the cup!

    The Asan cleanser is great for those of you who want extra reassurance. It means that your cup will smell great and it does help maintain your menstrual cup over time and stops it from discolouring.
