Titanium scratch marks on porcelain

+++

Q. I recently bought a titanium watch and now have discovered that it is the culprit that is marking my bathroom sink with small black 'scratches' which I cannot get off. I would like to know what does this and how I can clean up my sink.

Q. Hi Colin, Just wondering if you ever found a solution to removing those titanium marks. I have the same problem. Purchased a titanium watch for my husband a year ago and now both of our sinks have those black marks.

I tried Lime-A-Way [linked by editor to product info at Amazon] (suggested at another site to remove marks left by metal) but it didn't do a thing. I have also tried baking soda and a 3m green scrubby to no avail. I'm surprised I haven't removed the glaze from the porcelain!

Please tell me if you have discovered a way to remove them. Thanks,

Q. How can I find the answer to removing Titanium scratching on porcelain. It's a brand new white porcelain sink and pot marks have left these same little scratches as described in this other letter. Thanks.

Q. I, too am having the problem with my pots and pans leaving grey "scratches" on my new porcelain sink. I have been told that the sink will need to be "re-glazed", which I looked into and is very expensive and done by a professional. If anyone has an easier solution, please tell me!

Q. I've been using bleach with chlorine, which definitely takes out the black scratches but it lessens the glaze and you end up having to use it almost daily. I didn't find ANYTHING else that worked!

Like a former poster, Debbie B. of Florida, I too, am looking for something to bring back the shine on my porcelain sink? Does this require a professional or can the homeowner successfully do this? What product to use?
Thanks,

I have bought a "Pumice Stone"(who does not specified it will scratch toilet bowl) to remove Calcium,Lime and black water ring deposit into some off my boss bathroom toilet bowls in the house..The 2 white bowls came out clean after some soft rubbing and "elbow oil" then I did the same thing to our Black toilet bowl..Was fine when wet, but once it dry out it show so white scratch all over the bowl..Does anyone know how to get rid of these scratches, as I'm about to loose my job or buy a new $1500 toilet bowl.

I have tried everything to get the marks left behind in my porcelain sink and nothing worked. I finally tried some of my husband's Gojo. It worked great! All of the marks are gone.

A nasty dark scratch appeared on my less than 12 month old bathroom sink over the weekend. Funnily enough, my boyfriend was staying over and he was wearing a titanium ring (hmmmm....could this be the culprit of the aforementioned scratch?) I think it could well be after reading the previous posts.

I just had a scout around in the ol cleaning cupboard and tried Hob Brite - it worked a treat, so there's another one to add to the list :)

I also had those nasty black marks on my porcelain sink. went to the dollar store and purchased those rubber mat liners that you put underneath, so that you won't slide. cut off a piece and rub it on the marks....COMES RIGHT OFF IN SECONDS. :))))).

I noticed a dark scratch mark on my new porcelain sink. I don't know where it came from - yes, I do have a titanium watch, but I don't usually wear it when washing! Anyway, I tried 1200 grit wet/dry paper; came off in about 30 seconds with quite gentle rubbing.

We had this problem with my son's razor. After seeing the other replies I thought I need a paste that has abrasive particles in it. Answer toothpaste. A sheet of loo paper and a small blob of toothpaste was all it took. 2 minutes later it was perfect again.

I was wondering how to get marks out from a ring or watch etc and I was thinking T-cut would do it, Nope.. But because I was a valeter I did not give up so I tried another polish....

Worked perfectly and all are completely gone! Work it in and it will go, even using one finger and no cloth.

This solution may or may not work with titanium, but it is magic for those who have marked up their toilet bowl with an auger. Get Jobmaster Bathroom and Bowl cleaner (usually from Costco) or any strong bathroom cleaner with phosphoric acid. The Jobmaster stuff is pink with a slight cherry syrup smell. Flush the toilet twice (to make sure you have no other chemicals in there), then pour about one to two cups of the Jobmaster in the bowl. Come back in a couple of hours and the bowl will be spotless, no scrubbing needed! I never thought it would work so well. It removed every scratch, even in the area where you wouldn't be able to scrub unless you had very tiny hands. I figure that the scratch marks is iron oxide from the auger. Most acids should be able to dissolve iron oxide, but phosphoric acid is especially good at it (remember Naval Jelly?)

We too have a bore water supply to the toilet that leaves a mineral deposit in the bowl - the only effective way I have found to remove it is using a coarse sand mix and a damp cloth - form a pad with the cloth, dip it in the sand and use as a scourer on the pan - a bit physical, but it works and no chemicals involved.

i just moved into a new home and found grey marks in my porcelain sink.
probably from oven racks.
i looked here and followed advice for the glass stove top cleaner .
i popped it into the search engine and low and behold there is a homemade version.
i did think initially "yeah this wont work" but to my surprise it did.

White vinegar
Baking soda
i just gently poured the vinegar onto stain, sprinkled some baking soda on and drizzled a bit more vinegar on for good measure. left it to bubble for 15 mins and then scrubbed it.

it works almost 100%, I'd say about 96%, but not bad for things already in the kitchen

After reading most of the advice to remove metal scratch marks from ceramic, I tried a ceramic hob cream "Hob Bright" with a soft sponge and plenty of elbow grease and all 8 marks are completely gone and sink is like new once more.....Thanks for the advice

Toothpaste and elbow grease worked great!! The black marks are mostly gone and sink looks very clean, however there are teeny tiny scratches in the finish ... any idea how to refinish those?

I have tried many of the mentioned "cures" but never really got my sink mark free. I looked for the Cramer Plumbers Rubber, but unless I ordered online, it's not available locally. I have a pumice stone and was afraid to us it on my enamel sink so... as I was making a shopping list I noticed my pumice stone for pedicures. It is a lot smoother and finer than any other. In about 2 minutes I had 8 years of marks gone! I am spreading the word, it worked wonderfully! The easiest and cheapest "cure" yet!
