How do I remove turmeric stains from metal/plastic cookware?

Question

As much as I value tumeric for its rumoured cancer-battling qualities, I find its tendency to stain anything it comes into contact with (including 'stainless' steel) discouraging to the point that I use it much less than I would like.

In a previous question regarding a tumeric-stained marble mortar and pestle, it was recommended that bleach be used to remove the stain. Is this recommendation applicable across the board? Pots? Pans? Plastic colanders?

I hope there is some other way to remove these stains because I am starting to accrue tumeric stained clothing that I can't bleach, as recommended.

Answer 1

For hard, chemical-resistant surfaces such as marble, bleach or peroxide cleaners will help. On things like counters, pots and pans, a Magic Eraser will often take off the stain. Sometimes a harsher abrasive like Comet or Barkeep's Friend will be needed.

Softer or porous materials, including cloth and many plastics often CANNOT BE UNSTAINED. In my kitchen we treat turmeric like a dangerous chemical -- isolate, contain, and plan ahead to limit exposure. It's just that destructive.

You might as well tie-dye or bleach white any clothing you get turmeric on; it India it is used as a dye for saris because it will semi-permanently tint cloth. You can brush off the dry powder harmessly, but when it is moistened and allowed to sit for a moment, the color is pretty much permanent.

Edit: UV+peroxide: I saw a patent for removing turmeric stains from upholstery using UV light and hydrogen peroxide. You might try soaking fabrics in peroxide or Oxyclean (which uses peroxide) and leaving then out in the sun. Can't hurt right?

Edit: strategies to manage turmeric without making a mess

1. Plan ahead where you'll use it, and which utensils and vessels will hold it, so you don't mess up anything you don't need to.
2. Re-use already turmeric-stained items so you don't wreck anything new
3. Mortars and pestles, tupperware, wooden and soft plastic utensils are a lost cause. At least the stain is purely cosmetic?
4. ALWAYS ALWAYS ALWAYS wear an apron.
5. Keep spilt powder dry (it won't stain) and brush it off with a paper towel into the garbage. Brushing away promptly keeps you from inadvertently spilling liquid on it, or wiping it with a wet towel during cleanup. That is, unless you want a neon-green counter and towel?
6. Whenever you spill something containing turmeric, promptly wipe it off, to reduce staining.
7. Hard ceramic and porcelain are immune to staining unless the surface is rough. Try to use these for storage. Glass will stain. Stainless steel is resistant but not immune.

With these strategies, I find I can use turmeric regularly without problems.

Answer 2

Read this thread after trying a NYT recipe for roast pork, that turned out nicely, but left turmeric stains on a non-stick baking sheet. (The baking sheet had been in the oven under the roast.) In my case all sorts of products did NOT work, including chlorine beach. What finally did the trick was a spray solution of OxiClean applied to the cookware, with the cookware then placed in a 180 degree oven for an hour or so. Much, much more effective than OxiClean left at room temperature for days. Stain is gone completely, and the great thing is that the non-stick coating survived unscathed. Hope this helps someone else. My guess is that, for stained cloth, presoaking with OxiClean in near-boiling water would work.

Answer 3

try oxiclean - i swear by it. if it can remove red wine from whites, surely it can remove this. i am continually amazed at the stains i find it can remove where nothing else works.

Soaking in a solution of washing soda is often enough - the colour is mostly soluble in alkali. It can take time with a cold solution - overnight is good.

The bleach treatment works because it bleaches the colour, but also because bleach is strongly alkaline (it is stabilised with caustic soda). Washing soda is a milder option, and better for plastics.

Vanish can get rid of stains on clothes - you may find the stain is still there when washed, but expose the mark to sunlight on a washing line and it magically fades away.

Answer 5

We were making turmeric tea and we had to shred it. stained everything. "Ready to use oven & heavy duty cleaner" works for cleaning. This is the spray that domino's uses for cleaning greasy stoves. The turmeric turns copper red in an instant and is easily washed away! Amazing.

who told you that set in tumeric cant be removed? Just use tide to go!
