Limescale on quartz worktop

[BatshitCrazyWoman]

I moved into a house with quartz worktops in the kitchen (I wouldn't have chosen it). I also have an undermounted sink (again, I wouldn't have chosen it!). I live in a hard water area, and the quartz around the sink, draining area and taps has lots of limescale on it, which has made it dull. I clean the rest of the worktops with a damp cloth and buff dry, and they are fine. But the area round the sink looks awful! Can I use Viakal? Or is there something better.

Really missing my beautiful Corian worktops in my previous house 🙁

My worktop is Labradorite and I do occasionally use viakal around the taps and use the cloth over the surface. It works for me but obviously a risk. Would be a good idea to test somewhere not too noticeable first. I did get a quote for a refurb, around £600.

I might try it somewhere hidden first. I kind of feel like it can't look worse, to be honest. Thanks!

If I could replace the sink with a surface mounted one with a draining board, it would be better, but I'm not sure it's possible (or who I would get in to do that! Might do some research ...).

I have black quartz in a hard water area (not my choice - moved into it) and I feel you. I use white vinegar and a brisk rub with a microfibre cloth. This works. Viakal would probably work too (and quartz is pretty bombproof) but white vinegar maybe less harsh, and smells better to my senses. Method for marble/quartz afterwards brings up a shine. But black is pretty unforgiving of marks and smudges - at least I know now, and can go for a pale colour if/when we redo the kitchen!

Thanks @BigSkies2022 The Viakal made no difference 🙁 I have some white vinegar, so will tackle it again at the weekend. If I can't get it off I'm going to contact one of those companies that restore quartz. It doesn't help that the sink area is the first thing you see when you walk into the kitchen.

I don't envy you with black quartz! Mine is white ...

Ecover limescale remover is actually brilliant, you don't need something as harsh as viakal. Also citric acid is great but perhaps check its OK on Quartz.

I have an inherited black granite worktop and the only thing that's worked for me around the sink is using a Stanley window scraper to scrape off the limestone followed by a polish with extra fine steel wool 0000 grade. The steel wool works really well in the draining board grooves and around the sink.

Limescale remover, lemon juice vinegar and bleach are a risk on stone surfaces they can't differentiate between the limescale and the stone surface and will dissolve both.
