Limescale builds up fast in bathrooms and is hard to clean. It can stay on taps and shower heads.

It can also be in hidden areas like water pipes. This can look bad and cause problems.

Cleaning limescale is hard and needs a lot of work. I saw a lot of limescale on my taps, so I tested two cleaners.

Viakal says it's the best against limescale, so I compared it to Flash cleaner, which removes grease and limescale.

There was a lot of limescale to clean.

Some limescale stayed after using Viakal.

I bought Viakal for £2.65 and used it on my taps as the instructions said. I used one spray on each tap.

The instructions said to spray and wait three minutes. The spray was easy to use.

After three minutes, I rinsed and scrubbed the tap. But a lot of limescale was still there.

I could remove some limescale, but not all. I didn't use the spray again for a fair test.

I had limescale on my taps.

I liked the results from Flash.

Flash was £2.44 and had similar instructions. I left it on for five minutes.

The Flash spray didn't cover as much as Viakal. Then I wiped and rinsed the tap.

Most of the limescale was gone after using Flash and scrubbing.

I followed the instructions for the time.

Both products were easy to use and worked fast. But Flash was better at removing limescale.

I didn't need to use Flash again, and it's cheaper. It also removes soap scum and kills bacteria.

Flash can remove limescale, soap scum, and kill bacteria. It worked better and is cheaper, so I would choose it again.
