can any one help, last week i cleaned a just off white, loop pile wool carpet, (nearly new) and ordinary HWE process just would touch the dark traffic lane coming out of kitchen,

i was thinking , cus i going back to clean another room today, of using oxibrite,

is this wise? will it do the job?

i not used it before and understand it is 'controlled bleaching' so am concerned it may do strange things

Craig would not advise you to use this on wool as it is not a bleaching agent and could actually burn the yarn (dependant on wool type) and make it brown.
To make it look white again you would have to use Hydrogen Peroxide and this is quite a difficult task as you could make some parts of the carpet whiter than others.

Basically dirt discolours yarns and flock to make them shaded.
The collar on a white shirt will become dark after a few months of constant wear and even after thouough washing the dark shade it still in the collar even though all the dirt has been wased out.
This is known as shading and the same happens to walk areas on carpets.
All you can do is explain this to your customer and tell them that even though the dirt will be removed on the cleaning process there will be some shading afterwards.
When wet some types of white carpet walk ares will look quite dark but then lighten on drying.
The first company that comes up with a chemical that can completley remove all dirt from light carpets in cluding the particles that cause the shading will make millions.
Till then just qualify the shading to your customer before you start your clean and then you will get no come backs afterwards.

Hi Craig,

We have had this problem on a white wool berber in an office (who buys a carpet like that for an office!!).  On the first clean, it didnt really come up that well.  We looked at our kirby and found the beater bar wasnt rotating freely, so we fixed this, returned and treated the whole carpet with max strength pre-spray gold.  After 10 minutes agitation, we resprayed it then extracted using very slow wand passes.  The carpet looked much better and the client was happy with it. 

Oxibrite is a peroxy carbonate, akin to 25%+ hydrogen peroxide.  We have used it on white wool rugs (as a last ditched attempt to remove staining, but never on an entire carpet.  On the rugs, you can see the fibre beginning to pill in the areas treated with oxibrite, so unless there was no other option, i wouldnt recommend using it.

Others might have a recipe for cleaning manky white wool berbers, but ours is vac, vac, vac, vac, and then prespray gold.

Hope this helps

Graeme totally agree I think the most important part is the dry extraction so like you I also spend a long time vaccing before the wet clean.It makes a big difference on the lighter colour carpets as it helps stop the wickback.

thanks for the help guys, when i went back i did use it but only as an additive in the solution tank and did whole hall carpet, it did improve slightly.

ive used it a few times with great results but it takes a while for anything to happen more than 30 mins so probably packed up and left by the time it starts to work but try going back and having a look you would prob be supprised
