Out Damn Spot!

I’ve gotten a number of questions about how to remove spots from the blue and white china that I bought last weekend.

Here’s what happens with china. As it’s used and it ages, it gets very small cracks in the glaze called crazing. There’s not a lot you can do about a piece that’s already crazed. Dirt, grease and other disgusting things get into the crazing and cause discolouration. The image above is from a planter, so it’s probably dirt. In my pieces, it’s probably grease.

There are a few things that you can do to try and get rid of the stains. My friend Reggie Darling has a long piece about using hydrogen peroxide to remove stains. It’s a lengthy process, involving submerging the piece in hydrogen peroxide (H2O2) for several days and then baking it for a few minutes in an ELECTRIC oven (as gas ovens could cause an explosion!). You can read about the process and Reggie’s results, here. They were dramatic. You can either get lots of smaller bottles of H2O2 at the drug store, or a larger bottle, which is a higher percentage, at a beauty supply store.

Another suggestion is to make a past of a cleanser like Comet®, or something that has some bleach in it, and spread it over the stains. You can leave it overnight and see what it does. Do not use bleach full-strength as that can damage the porcelain.

Since the old tureen I have is already pretty badly damaged, I put some Soft Scrub® on it and left it all day long. The process cleaned the dish up a bit, but some of the stains go all the way through the china.

The piece does date from the 1830’s, so that’s excuse enough for me to be a little worse for the wear.

Other suggestions for cleaning china are denture tablets, water softener with a Z code, and naval jelly, which is terribly caustic. Natural options include a paste of white vinegar and salt, baking soda and water, or a past of Oxyclean® and water.

What are your tips for cleaning china?

  1. I actually really like crazing and I look for it in old white or cream platters. Stains are not always so nice, so I'm going to try some of your remedies.

  2. A porcelain restorer I once knew used thick household bleach dipped into good quality toilet paper then laid onto the stain. She always maintained it had to be good quality paper and not the cheap stuff!

    1. That's pretty funny. Wonder if you could use paper towels?

  4. Hi Meg, I think that you have listed everything that I might suggest. Having been a collector of English blue and white, I began to love some of the old staining--gives the pieces history and a bit of mystery. I do love all of your finds.

    1. Sometimes the staining looks good, other times, not so much!

  5. Your friend RD has stepped away from blogging. Is there more to the story BTW We have not had a Conner update .... I have only recently discovered other blogs from fav bloggers and now find many are also hanging up the blogging hat. At least turn to Webstagram to keep the vibe for example that Eddie Ross seems to webstagram more than Blog as in blog.
