It is the crazing that has allowed the oil and grease to penetrate the glaze and discolor in the first place.

When items have survived 100 to 125 years, there is nothing wrong with allowing items to age gracefully When unsure about the process to use ,it is best just to leave the piece alone.

But it has large darkened areas of brown both inside and out. I plunged it into bleach and then decided to do a google search on cleaning antique porcelain :( I have since plucked the sugar bowl from the bleach! And I am wondering if I can still use the peroxide now. Help! Hello Maggie,

It doesn't work quite as well on porcelain in my experience. My technique is slightly different and quicker but still using 40 vol hydrogen peroxide obtained from hairdressers or their wholesalers. I soak cotton-wool in peroxide and apply it to the stained areas. I then apply clingfilm over it to keep it in place and prevent evaporation. Then I put the item in my kitchen oven at around 50 to 80 degrees centigrade for a few hours, maybe even overnight. The higher the temperature the less time is needed. Let the item cool slightly before removing the film and cotton and wash thoroughly with warm water and detergent to remove any fatty deposits on the item. The cotton wool will be yellow or brown with fat and grime. One disadvantage is that it removes the paint from some restoration so I wouldn't recommend it if you think your item might have been restored I have used peroxide several times to clean crazed pottery with good results.

I suspect that the serving pieces were freshly washed and still were not completely dry when the bubble wrap was placed on them. There must have been moisture that had seeped into the crazed areas. I believe this is what caused the discoloration along with old grease. Follow the steps and they should be back to normal and ready for your Thanksgiving table before you know it! Thank you for using WorthPoint. Maggie Michelle,

They had crazing when I packed them. When I unwrapped them they were so gross. The crazing is very dark now and there are dsrk random stains. Could the plastic bubble wrap have caused the discoloration? I will get 40% peroxide and try it. Sure hope it works, I love these dishes!.

Do I use the peroxide alone or do I dilute with water. Will it remove stains from hairline cracks. The peroxide I have brought says 40 vol 12% is that ok. thanks so much julie Hi Maggie, I am trying to get stains out of an old shelley dinner set.

I had success and it soaked for a couple of months because the stains were so bad. Believe it or not there was no change to the color of the gold trim. It is always a risk to use chemicals on antiques. Why don't you try soaking some paper towels in the Peroxide and lay them on the areas that are still stained. Put the plate in a sealed plastic bag and make sure they remain moist. It may take a long time to work. With patience hopefully this will work for you. Good luck!

However, what to do when one has old (c.1840s) gilded china? I'm not brave enough to submit them to the peroxide. I think it will just irreparably tarnish the metallic color. tried soaking same in strong solution of boraxo in water (c0vered). this did work but, only up to a point.

If there is grease residue after soaking the item, put the it into a cold electric oven and raise temp only to 175 degrees for up to 30 min. Use warm water with mild detergent to remove the grease. Can be repeated if necessary. Important….do not use a gas oven to remove the peroxide from the dish as hydrogen peroxide is volatal.

I wish I had seen this a few weeks ago when I found an entire set of crazed china in boxes that appeared ruined because of dirty crazing. But I wish the article had mentioned whether the porcelain is food safe after this treatment. Obviously, you would hopefully not eat off dishes with dirty crazing, but what if it becomes clean again?
