Made the s#!tty job less s#!tty!

Purchased both the toilet fizz & wee fizz. Both absolutely fantastic!!!! They not only smell amazing and mask the usual feral toilet rv odours but actually pleasantly surprised us too at how amazing they actually work in breaking down the organic matter too. Made the s#!tty job less s#!tty!!! Fantastic product will be purchasing more. Regards, 2x Happy Campers 😊

Great product ! Smells awesome and does the job

Great product for our cassette toilet in van. No nasty smells and does breakdown the icky stuff. Have been using only this for a year now and our new van arrives next month so we will continue to use .

Bernadette Heath

Extremely impressed, we are now using the citrus twist toilet fizz and no more yuck chemical (or other ) smells, and surprised just how well everything gets broken down. Just ordered another bag, wont be going back to chemicals again, and citrus smell is quite nice. Just bought the grey water tank cleaner too, thanks

My second order arrived today.
I am so glad I gave this Wee Fizz a go. Game changer for me as I am so sensitive to chemical smells. I am beyond happy. The smell of this product is so much nicer than the chemical products. Thank you so much for a great product .
If you are thinking about giving it a go jump in.

Bought two of the small Van Fizzers for the cassette toilet to trial, as I hate the chemical smell of all the others. It has surprised me with how well it works, no chemical smell & the toilet didn't smell.
Bonus that it is a small Australian-owned & made business. Prefer to buy Australian-made/owned products.
