Hands down my best seller by far! These mildly fizzy, Rosalina toilet cleaning tablets are hand made in small batches and not only smell great, but are also made from all natural, organic ingredients in home compostable packaging. These are not bath bombs and will not fizz like them. Lil'Bit Rosalina Toilet Cleaning tablets are made to clean loos and kill off that bacteria. When the tablet is dropped into the loo, the citric acid will fizz slightly BUT you may not be able to see what's going on from above, but as you can see in the video here, there is plenty happening beneath. The tablet will collapse leaving a white powder in the bottom of the bowl which acts as an abrasive when swished around the bowl with your brush. Rosalina is also referred to as the Lavender tea tree and is an Australian Native oil packed with antibacterial properties. Its scent is slightly woody, camphoraceous and floral with rosy undertone. You can also use them as a kettle descaler!
