cooking pots going black

hoseman

I have a gas hob ,every time i use it the pots end up getting a sooty blackness on them,what is the cause?have gas hobs to be adjusted ?the pots are stainless .

Poor Uncle Tom

Impurities burning in the gas, with gas cooking this is unavoidable. Avoid putting the pots in the dishwasher and wash them separately with rough sponge water and dish liquid.

stop using this immediatly - wrong jets to wrong gas

usually happens when a natural gas hob is being used on lpg or bottle gas hob or vice versa

extremly dangerous

gas is a clean burning fuel ,once set up correctly. there is a problem here that was avoidable .

if any gas appliance burns black always switch it off and call someone in who knows what they are doing

Any marks on my pots are removed using a sponge and wash liquid in water, as I said. I have my cooker checked and serviced regularly and regardless of how clean the gas is I have found that there will always be marks.

Regardless of whether there are marks or not it is always wise to have your cooker checked and serviced regularly.

One of the things I've found with gas hobs is if the flame is set too high it licks around the sides, all that heat is wasted.

Simplest way is to reduce the heat until the flame remains under the pan, any extra heat is just wasted as well as blackening the sides of the pans.

if you read the post they said soot - any gas appliance that produces soot needs to be shut down immediatly and the cause found . i am an rgi and deal with it all the time , usually down to being misinstalled ,or in older applaiances gas pressure fluctuations up or down .that hob is producing huge levels of co2 which in turn will/can reburn to create carbon monoxide .

if your own cooker produces soot i would be questioning whoever 'services' it for you .

to be 100 % clear on this

heat marks are ok but if soot appears shut it down

if you can rub your finger on a pot and black soot comes off you have a problem

For peace of mind lets ask the OP to discontinue use of the appliance and also when it was serviced/checked last? and maybe even a picture of one of the pots if it's not too much trouble.

I am very happy with the person who services my appliances, not only is he a professional but he is a very experienced one.

that you might be ,maybe you could ask his opinion on soot on pots .

i am talking from experience doing this job a long time so you will forgive me for coming across as annoyed when i see a moderator giving out advice about using soap and water to clean soot off pots ,when i know what the cause is and what the potential outcome could be .
there is freephone numbers you or the op can ring to bord gias or rgi . they will give you the same advice shut it down

Gas Safety

1. Do not use any gas appliances that you think may have a fault
2. Ensure that all gas appliances are serviced at least once a year by a member of
RGII: www.rgii.ie
3. Ensure that all ventilation grilles and outside flues are never covered or blocked.
4. Fit a Carbon Monoxide Detector
5. Be aware of the position of your gas meter and mains valve.
6. Ensure that the 24Hr Emergency Line number is in a visible place.
Carbon Monoxide

If any of your gas appliances are faulty they may produce Carbon Monoxide. This is a dangerous by product of natural gas. It is colourless and odourless.
Gas flames should be blue. If your appliances are burning orange or yellow there could be Carbon Monoxide present. If in doubt you should have the appliances checked by a member of RGII: www.rgii.ie.
For further information on Carbon Monoxide or to arrange a safety inspection please call: 1850 79 79 79. The Carbon Monoxide phone line is open Monday - Friday, 8am-9pm and Saturday 9am-5pm.

You are making assumptions here that may not be right.

I use LPG which doesn't burn as clean as natural gas and does mark the pots. If you check you will notice I don't mention soot once.
Most of your post is based on Natural gas, which may or may not be the case, we don't know.

I mention how I get rid of the marks on my pots which will tell you what I assume the OP is talking about. It is also clear that a sponge, soap and water will not remove soot, which also indicates the marks I am referring to.

With your years of experience, surely you can see that! As an added precaution you will see the message in my last post in case I mis-understood the OP.

It will be interesting to see if the OP has any pictures.

Has to be the jets, double check that they are the correct ones

What cooker and what gas, this sounds like an incorrect set up, soot indicates poor combustion which in turn indicates the production of carbon monoxide.
Do not use.

wytch

Pots going black, is DEAD DANGEROUS. Somebody could end up dying. Stop using the appliance and get a registered gas installer to check it out.

It's called gas safety and paranoia keeps people alive, the idea of advising washing away black marks after a clear warning was given is fool hardy as it can lead to confusion and people disregarding important safety advice, incomplete combustion can have a effect on a persons health and well being.

This is a country where DIY cooker/hob installs are common place, soot/black marks is one of the first indications of incomplete combustion as well posted and should never be ignored, it is not acceptable for any appliance to produce soot/black marks and there is always a reason for it that would need to be identified.

That is very clear as is every warning on this thread which the OP should get when logging back in again.

And as a Mod on this board maybe you'd do well to remember the advice before arguing something you clearly have little knowledge of when it comes up in the future.

Please don't argue on thread, it is a breach of the charter, which you should read before posting again. Infraction given.

Billy Bunting

It was advice, but apparently you decide if thats the case.

That's unfortunate, when it comes to gas safety RGI's can get a bit grumpy:eek:

DGOBS

+1, the advice (not arguements) that seasoned gas professionals are giving here should be listened to, and an infraction given IMHO should be revoked with an apology. This type of advice SAVES LIVES

Soot is a primary indicator of carbon monoxide production, and all the soapy water in the world won't protect the OP

Your assumption that LPG burns dirty is also incorrect, I service many LPG cookers, jobs, fires, boilers etc and all burn clean

Duty Of Care, we all need to play our part.

Billy Bunting

I hope your not arguing chaps

hoseman

thanks for all the advice .i will get somebody who is a registered gas installer to check it out before using it again

Thanks for getting back OP, Time to rest this thread!
