Cleaning a sink

21 years ago

I'm new to this forum and I need some help with my kitchen sink. It's made of reconstituted black granite. Over time, it's got a pale haze on the surface that I can't get rid of. I've tried everything I can think of to clean it. Any ideas?

on anything else, I'd say it was a calcium deposit, and that if vinegar didn't work, CLR (Calcium, lime, rust remover) would...but I've never worked with 'rock dust in aspic' before, and about all I know about them is that you're not supposed to use acidic cleaners on them.

drat- I hate not having an answer!

Thank you for trying!
I've been told to try lemon juice, dishwasher powder and vinegar but no use!

A paste of hydrogen peroxide and cream of tartar really leaves a white sink sparkly clean without scratching. I hate using abrasives on porcelain and I would think your type of sink you would have to be very careful. Contact the company that sells this type of sink for what is safe or not. Good luck.

They suggested the dishwashing powder which did nothing :(

I would contact a granite fabricator company and/or someone that sells or installs granite. Absolutely stay away from anything with concentrated sodium hypochlorite (bleach) or acids like lemon or vinegar. They will permanently etch the sink. If it is dull, it may already be etched, in which case I wonder if a granite specialist can re-hone it for you.

You may also want to post over at the tile setting forum at www.johnbridge.com - the guys over there are in the trades and specialize in installing tile, granite, and other stone floors and counters. Especially Mario B. He would be able to advise you, if you can clearly explain the situation.

why not try a little murphy's oil soap in a small area,, maybe the oil in the product would remove the haze. or try a little mineral oil.

Y'know- I think Dragonfly might be on the right track- since it IS reconstituted, it's in a acrylic base, and while one simply does not 'scratch' granite, it's VERY possible to scratch the acrylic with scrubby pads or even the grit from rinsing spinach, over time...

if the oil works- give it a good scrubbing, let it dry overnight, and try a sealant meant for stone countertops (usually billed as 'marble' sealant)

I always try baking soda on something. Can't do any damage and does clean LOTS of things.
