Hi all

I was rung today from a woman I did a job for midweek. It seems a meter section of her carpet I cleaned successfully had developed a brown like stain.

Although I am going to see it on Wednesday it was definitely not there when I cleaned the carpet. I have some Debrowning in the van but have never used it before.

Does it sound like that? If it is browning I would have thought that would have effected the whole carpet? Right or wrong?

Please let me hear your comments on this as in over 3 years I have never had this problem 

Thanks

Sky need more info such as

carpet fibre type

cleaning method used eg pre vac

chemicals etc

Could just be wick back.

Hi

Yes pre vaced and used hot water extraction (Extracta Excell). Not sure of carpet type but was a light cream colour.

Hope that helps

If your cleaning a light cream wool carpet, keep the ph to mid range or lower.
If it needs degreasing or it's heavily soiled, there are many wool safe products on the market.
Could be you used a high ph  prespray which could have caused the browning.

Try recleaning and use your debrowning as instructions.

Yes thx for the comments. Ill sure use the debrowning powder at a lowish temperature (as the container instructs). Hopefully that will sort her problem out.

Ill also take some pics to be sure to show you guys if there are any further probs. Thanks for the help

Sky you need to do a fibre test and check construction before completion this time as it may no be CB but just wick back and a low moisture acidic rinse extraction or bonnet may be suffice.

What are the principles of doing a fibre test? What should I do? Ive never needed to do any of this before? Thanks

If your not sure to what the yarn is of the carpet your about to clean you need to do a burn test ( basic trainning courses teach you this). The Cel browning will only have happened if it is wool or has a wool mix and this would have been done by you over wetting or using a chem with  high ph.
If it is a synthetic yarn eg nylon,polyprop etc it will not be Celbrowning but just wick back, this could be due to not enough prevaccing or not enough rinising on final extraction.

Thanks Paul. So when I go back would you recommend I do a thorough vac, debrowning solution + cleaning powder and warm water & rinse the problem area of the carpet? Do you think that should do the trick?

Im pretty sure it is wool due to the sheep smell that came out of it (even though I put some Flourosan in to compensate the smell).

Thanks for the advice

Thorough pre vac
Spray be browning solution
give it the relevent dwell time
extract with warm water with an acidic rinse /or a weak solution of debrown in rinse tank.
do plenty of dry passes and use turbo if you have one.

Dont add a bacterial deodoriser when you have finished.

Most wool carpets give off a musty smell when wet it is Lanolin which is naturally present in wool and sometimes can be very strong smelling,this will go when the carpet dries,just qualify this to the customer before the clean so she knows what the smell is.

If it is a heavy gramme wool it will take several hours to fully dry

Have a look at this http://www.ditzyprints.com/dpburnchart.html

This will give you the info to help distinquish different fibres. This should be carried out before cleaning anything if you aren't sure what it is. In time you can tell just by looking, sometimes.
For testing carpets, take a few tufts from the edge, around radiators is a good place.
Carry a lighter, small pair of scissors and a pair of tweezers in a small tin along with a copy of the burn chart.

Did job this morning, carpet seemed ok but hard to tell when it was damp. Hopefully that will be the end of it 

[conallon]

The problem youve had as been caused by the application of clensan,(which is a animicrobial not a de-odoriser) it as soaked through to the backing
There is no need to mask the damp dog smell of wool
Tell the customer the smell is a sign of an  exspensive carpet and will disappear as it drys

I'm impressed by how "grown up" carpet cleaners are.

If you mentioned "browning" someone's carpet to the window cleaners you'd never get a serious reply.

Yes I used to play snooker and was always leaving brown on the bottom cushion!
