Caravan toilet chemicals are simply chemicals that you need to put inside your caravan toilet in order to keep it fresh and clean, but also to maintain your toilet. The difference between caravan toilet chemicals and regular toilet cleaners is that caravan toilet cleaners are specially formulated to help the break down of waste which makes the disposal of waste a lot easier to handle. Since you don’t need to manually empty waste from you toilet at home, regular toilet cleaners don’t focus on the break down of waste, and instead focus on removing germs and leaving a fresh scent in your home.

Whether you get liquid or dry toilet chemicals for your caravan toilet, there are two different types of chemicals, blue and pink. Below is an explanation of the difference between these two colours and what they can be used for:

Blue caravan toilet chemical

The blue toilet chemical is often the most popular among caravan owners as it takes care of the biological breakdown of waste. It is used to ensure that all the waste is completely broken down and easier to dispose of. To use this caravan toilet chemical, it needs to be poured into your waste tank and works to keep bad smells and build-up of gas under control. All you have to do is pour it in your tank and let it do it’s magic.

Although the blue chemical is the most popular, some people prefer to use the lesser known green toilet chemical due to its environmentally friendly nature. The green chemical does the same job as the blue but contains chemicals that are not as harsh fro the environment.

Pink caravan toilet chemical

The pink toilet chemical is perfect for maintaining your bowl and making sure it smells good, and works with the flushing water. This one works just like the toilet cleaners at home and once poured, it coats the bowl with a protective layer that helps to prevent lime scale. It works to remove grime, odours and bacteria while keeping your caravan toilet fresh and clean.

Liquid vs dry chemicals

As well as choosing between the blue and pink toilet chemicals, you also need to decide whether your toilet would need liquid or dry chemicals. Liquid chemicals come in the form of concentrated fluids and dry chemical come in the form of tabs or sachets.

Liquid Chemicals

Liquid toilet chemicals are know for offering both cleanliness and efficiency as they are the easier to put inside your toilet. Since it is similar to use as regular toilet cleaner you use at home, many people prefer this over the dry chemicals. Despite being newly introduced compared to the dry chemicals, they are are very quickly becoming a favourite in many caravans.

This popularity may also have something to do with the fact that they are generally more environmentally friendly as well. as previously mentioned, the green chemical is very similar to the blue one in terms of how it works, however due to less chemical usage it is more environmentally friendly. In addition to this, since liquid chemical are concentrated, less product needs to be used, meaning that it will be creating less plastic waste, and retailers can save fuel and air miles as they can now can ship more product in one load.

Dry Chemicals

You can also get dry pre-dosed tablets and sachets for you caravan toilets. An advantage that this chemical has over the liquid chemical is that you can save yourself a lot of space and weight in your caravan as dry chemicals come in small light and compact designs when compared t the 2L bottles of liquid cleaner.

These tabs and sachets are also great for people how make a mess when pouring liquid cleaners, or those people who never know how much cleaner they need to be pouring into the toilet as it comes in an easy pre-dosed tab or sachet, meaning no mess.
