Never seen anything like this before, his wife had flooded the bath, he has recently moved back into the house after renting it out for 6 or so years, my guess was whoever lived there in that time had a bit of an addiction to shake and vac, or possibly some other type of supposed carpet cleaning powder ?
Have said I will accept no responsibility if it does return and he was happy with that, the entire house was like this..

Looks to me like water marks from a flood.

Well she did flood the bathroom, but the entire house was like it to a degree

[Kinver_Clean]

A good example of flood tide marks. With any luck it should come out. I would rinse with plain water first to see what happens, there may be a high concentration of residue from a bothched clean.

[M.Acorn]

It did all come out, but was just concerned it may reappear , gave it a good flushing out, so we will see

Did you put an airmover on it?

Forcing the drying process would help any wick back / reappearing problems.

To me it looks like someone has been on thier hands and knees and tried to clean it using 1001 or some other crap from the supermarket. Looks like soapy tide marks. Seen similar problems before and this was the cause.

Forcing the drying process would 95% of the time garantee it not to reappear.

Where's the evidence to back this claim up? Why by using an air mover/s will it guarantee the non return of whatever this is or any other stain?

The white marks in the carpet are the salts or contominants that were in the water that flooded the carpet. As a wet patch dries from the perimeter in,  the contaminants wick to the perimeter and concentrate there.
Using air movers to dry the area quickly stops any contaminants from concentrating into a particular area.
I would l recommend some training if you are not aware of these situations.

      Strange white marks all over carpets

Could it be a powder that contains a bleach, (not familiar with your brands over there), has been sprinkled onto the carpet. ?

Otherwise I would go with a cellulosic browning stain if your carpet is jute backed, although the white colour and the grainy type pattern is not consistent with water damage, in my opinion.



Shorty.

Maybe she was using bath salts. And she may have puts some in the bath too.

Arh, now you've edited your post it makes more sense and negates my question.

It could be that the carpet is layed on a concrete sub floor and its effloresence  coming up through the wet concrete into the carpet 

[M.Acorn]

Was in a 3 story house, only the ground floor was concrete, other rooms have wooden floors, it was powdery I gave the worst area on the top floor a rub and powder was evident.
The only area that was not really bad were the parts of the stairs where the powder did not stick

Hi Guys

I would be 99% sure these are sodium salts, primarily carbonate deposited due to water.

They can be quite insolouble but hot water should do the trick.

An advanced solution if a line persists is to use some hydrochloric acid but you must know what you are doing and test to see if the carpet is colour fast first, this is a solution only for those with good chemistry knowledge and practice, gloves etc.

I think when someone writes this then carpet cleaning is getting silly. Clean the carpet as normal, dry it if possible & if it comes back the customer will just have to replace. Putting Hydrochloric acid in a carpet, I've heard it all, really for heavens sake. You could do more damage by using that stuff than anything else and not only to the carpet....  oh, we're carpet cleaner's not industrial scientists!!

What do you think is in rust removers?

[Doug Holloway]

Hi Guys

I did think hard about introducing a bit more chemistry than usual but did stress it was only for those with a good grasp and technique.

There are quite a few carpet cleaners who understand chemistry, some of us even worked as one

A few days ago a thread was running on 'Professional or Trade'

This gives  a pretty good example that the two catagories exist and both are represented on this forum.
