Wickback after bonneting
« on: September 30, 2011, 07:53:29 am »
Hi
Did an office low profile where there had been a leak from the roof. Carpet came up fine but the flood mark came back after a week. Went back and recleaned. Again removed the stain but worried it might come back again. Used Surround free and heavy duty pads. Was worried about HWEing it with the possibility of wickback but as I said the circular marks came back anyway!!
I think they are going to reposition the tiles under desks if the stains come back again but obviously this is a hassle and would prefer to sort the problem out for them.
Any ideas on how to prevent the wickback after bonneting?
Cheers John.

Water staining from leaks are very difficult to remove. It is not wickback just a general issue with this type of stain. Its the same on ceilings. You have a big brown circle which is bone dry but if you just paint over it it will return within days. You need to put a stain blocker on it. Obviously you can't do this to the carpet. Rotobrite 2 can be succesfull in these situations but not always.

We used to have a contract with a water cooler company to go and clean up leaks and spills from their coolers in commercial premises and hotels and seemed like the easiest job in the world

Until we realised hardly any of the stains would come out,  had to visit one place 7 times once as the stain just kept coming back,  they always seem to disappear with cleaning but are back again in a few days.

I tried hwe  t/m and portable, l/m,  dry granules and getting on my knees and scrubbing even dry cleaning solvent and nothing  ???

I did some research at the time and it was suggested it was residue from the backing of tiles or the adhesive that was causing the stain which was obvioulsy mobile when it was flooded then dried back on the tile.

whether this is the case or not im not sure, but i do know they are a devil to do anything with and it makes it harder as the customer will normally think its just a water mark that should come out easily.

I steer well clear of these now ( and water cooler companies ) but if i have to will tell them straight its probably impossible to remove.

Saying that some are sometimes just water marks  ;D

Quite often it's more to do with the type of commercial carpet rather than the stain itself. You get to recognise the ones that are no hopers and the ones that look awful but clean up easy. ;D

Try misting with an encap then agitate with a pad. Then put a blower on it. As has been said always say you don't hold out much hope and then any result is a miracle. 8)
It's not expensive, you just can't afford it.

This is a situation where you hot water extract to remove as many of the contamiments as possible they bonnet to dry the area to eliminate the reappearance of the stains.
It is quite simple why this type of stain will reappear but would be a lenthly post and do not have the time.

Peter,

it would be extremely helpful if you did elaborate a bit  :)

As the stains i dealt with were far from simple, and i understand the whole hwe and bonnet to dry thing etc

With water ingress it is not the water itself that causes the stain but the salts and contaminents etc that have  been disolved in the water.
When it dries out the salts normally concentrate to the edge of the wet patches, as it dries from the perimeter of the wet area the moisture wicks from the centre of the area to the outside as the water evaporates the salts are left in the carpet.
You need to disolve the salts again and extract them to remove them from the equation. Drying the area with a bonnet with stop them from reappearing. Although many on here cannot understand it you are removing very little soil from a carpet by bonneting alone. Ok you can improve the appearance but actually removing very little soilin the process.

ok fine,

but thats just general advice regarding general water marks on low profile carpet,

There are situations that go far beyond the salts deposited on the carpet when real damaged has occured and no amount of cleaning will rectify it.

This isnt general wick back but a semi permanent stain, its good to know the difference as it can be a right pain going back thinking you can do something when in reality its not possible,

Hi Guys

I agree with Peter and have been experimenting with a fairly radical approach which I will post on when I am more certain.

Cheers

Or you can explain all that to the client, and cheat and lift a tile or 2 from a cupboard or under a filing cabinet ;)

I did say that I did not have time to answer and I did not because a lot of factors come into play here. With water extraction on a tile it is different to dealing with the majority of carpets as you do not get airflow through the product itself. With the majority of carpets that you clean you are able to get airflow through the backing of the carpet so that you are not washing dirt to the base of the pile.
On a tile the airflow that is created from the wand sucks air from around the fibre that you are cleaning so this will take soil down before it is sucked back out. Ths also adds to the problem of stains wicking back because unless you thoroughly rinse the stains will wick back through the pile whilst drying.  As well as bonneting after extraction I also use oxidisers a lot of the time, good results can be achieved but it all gets better with practice. Knowing what is achievable and what you promise the customer is important. on a large job it is nothing to add £150 to a job to return a few days later to apply an oxidiser to any marks or walkways that need any extra attention. (when I say a large job I mean 750 sq mtrs +).
As regards really bad stains the majority of commercial tile are polyprop or nylon Just put lots of oxidisers in your solution. You have to weigh up every job as long as you arte not dealing with a wool content tile they are incredibly resilient things......................
