While nobody likes to talk about toilets, we all have them in our homes and use them.
As a result, toilets get dirty and old toilets are often plagued by unsightly stains. However, a clever mum has discovered a Scalex Bunnings hack that could be the answer to all your toilet woes.
KEY TAKEAWAYS
- Scalex is a Hillmark heavy-duty descaler that removes calcium, lime, rust and mineral stains from toilets and tiles
- Available at Bunnings, Coles, eBay and Amazon
- Pour into the toilet bowl, leave overnight, scrub lightly and flush — repeat if stains persist
What is Scalex?
Scalex is a heavy-duty home descaler by Hillmark that removes calcium, lime and rust. It can also be used to descale home appliances, clean white or pale-coloured tiles or grout, and apparently your toilet too. As well as Bunnings, Scalex can be bought at stores like Coles or online through eBay, Amazon and other stores.
With this hack, the mum revealed her discovery in the Facebook group Mums Who Clean, and said she was having issues removing stains from the bottom of the toilet caused by mineral deposits in the water over time.

All you have to do is pour Scalex into the toilet bowl, leave overnight, give a quick clean with toilet brush and then flush. You’re left with a sparkling white toilet, with no effort at all! You can see the results below.
According to the Mums Who Clean page, if at first you don’t succeed with Scalex, try again a few more times.

And it isn’t just this one group of mums who are impressed with the product. Product Review Australia features reviews from customers who have bought and tested the product themselves.
“I have had black and brown stains in my toilet for years, and I have tried EVERY single product available to clean it, even home remedies didn’t work,” one reviewer said.
“I dissolved Scalex in boiling hot water and waited for it to cool slightly, as boiling water can crack porcelain. Emptied the water in the loo, added the dissolved Scalex, sprinkled a bit more and left overnight. Next morning I only slightly scrubbed and everything disappeared instantly! It looks brand new.”
So, if you have toilet-cleaning troubles at home, Scalex might just be the answer. But you could also try citric acid for another low-cost hack people have raved about.
