If you’ve ever spent way too much time scrubbing your shower glass, only to be left with streaks, smudges, and stubborn soap scum, you’re not alone. For many, tackling soap build-up feels like an endless chore. Soap scum clings to shower glass, turns once-clear surfaces cloudy, and refuses to budge no matter how hard you scrub.
Fortunately, a $14.49 product is changing the game, effortlessly restoring shower glass to a crystal-clear finish—and shoppers can’t get enough of it.
The product causing a stir is the $14.49 One Shot Thick at Bunnings, a concentrated acidic toilet bowl cleaner that can also be used on shower glass. Its ability to tackle calcium and soap scum buildup has made it a hot topic on social media platforms, where users are sharing their astonishing before-and-after results.
Professional cleaners and homemakers alike are singing the praises of the miracle cleaner for its effectiveness on even the most opaque shower screens. On social media, a local cleaning service demonstrated how the product starts dissolving grime in seconds, reducing the need for excessive scrubbing and promising a gleaming shower in under 10 minutes.

Their video captioned, ‘By using the right Chemicals, Tools and Equipment, you can achieve a perfectly crystal clear shower screen using just [one] product which is called… One Shot Thick,’ already went viral with over 1.2 million views.
Meanwhile, a different user shared her success with One Shot Thick on her rental’s shower glass, which had accumulated over eight years of hard water and soap scum.
‘Been renting this place for [five] years, I tried everything to no avail until now,’ her social media video’s text read, with the caption, ‘Definitely the best thing I ever tried on shower glass.’
The visual transformation is evident from the start of the clip, showcasing a clear distinction between the previously cleaned side panel and the main door. Although a slight residue remained on the door’s edge, the user celebrated the ‘major improvement.’

If the “dirt” is what most screens have it’s actually etched into the glass, no amount of a liquid product will remove that. Needs a glass polish to actually grind the glass smooth again.
I have discovered OzKleen Descaler Power. It is absolutely brilliant. I live in a hard water area and nothing else I tried would remove the lime scale from my shower screen. With OzKleen you just squirt it on, leave for 30-60 seconds and then rinse off. You might have to do a few patches where it’s missed, but generally it is an excellent product.
Where can I buy this in a bricks and mortar shop?
