Just done a quote from a leaflet drop some 7 weeks ago.
When i did a dye test, the colours ran i tried 4 different chemicals with the same result so i had to decline the carpet clean even though i havent much work Grrrrrrrrrrrrrrrrrr. Paul

I've sent you a PM

Paul
What chemicals did you use in your tests?
Derek
-
Derek I tried Promite , ultimate master and two chemicals from craftex even plain water made the dye run. The chap told me they were antique and cost £7000 . I feel not doing them was the best thing to do paul

Paul
Did you try an acidic cleaning agent?
Derek
-
Derek no i didnt try a acid cleaning agent The dye movement worried me Paul.
-
Paul,
Under the circumstances you did right to walk away.
However as Derek has intimated, an acidic cleaning agent may have been safe on these dyes.
I have frequently use an acid pre-spray as a dye stabiliser. This has enabled cleaning with a neutral or very mildly alkaline cleaner. The same dye stabiliser is then used as a post-spray to prevent dye bleed during the rapid-dry.
I would not have even considered Ultimate Master for these rugs.
-
Thanks for your comment, another lesson learnt, glad i walked away john why would you not consider ultimate master, Paul

Hi Paul
I believe like Big Brother John you may well have been able to clean this rug on the acid side...
Chemspec's 'Colorfast for rugs' followed by acidic rinse would have possibly done the trick...subject to testing that is... if colour movement is really severe then a prespray with an acidic rinse agent is another option.
I would stay away from any alkaline product on items with a potential colour problem even those which are said to self neutralise.

Would be interesting to see what the ph of your water is.
I tend to pass on rugs which run with water or acid rinse. May try the chemspec route.

Paul,
Though self-neutralising, the pH of the product in use is too high to be woolsafe, and it is the in-use pH that would affect the unstable dyes.
-
Isnt it the golden rule, that if theres a transfer with both the alciline and acid test....you run?...i would too
£7000...thats a lota dosh.

Hi Scott
If the colour bleed tests prove positive with acid and alkali solutions then you could always consider a dry clean method!
Where there's a will there's a way.... or it may just be me trying to be a hero!

Scott,
As 'The Wizard of Wigston' has suggested, lateral thinking can often come up with a solution.
I have even cleaned such a rug with alcohol in the past.
When being a hero, charge heroic prices.
-
This may not work in this case and i wouldnt touch the rug myself but would interesting to hear from the cleanitup gods if the idea may be viable.
Would it be possible to mix a ph neutral micro splitter (solutions number 4) with an acidic rinse and then dilute to stabilse die bleed and still benefit from the micro splitters cleaning properties???
Just a thought Paul
-
Paul,
This is not an approch that I would advise.
The best approach is to:
- First stabilise the dye.
Test with a cleaning agent.
If safe proceed with the clean.
Re-stabilise (lock) the dye.
Dye stabilisation is not always a simple matter of pH and some stabilisers require a dwell-time to achieve the effect. Mixing the cleaner with the stabiliser precludes this.
John.

Thanks John, I expected the idea to get shot down.So to initially stabilise the die would you (providing the die in question is not acid sensitive) do this with an acidic rinse and then test with a cleaning agent which presumably would be pH neutral or very close?? Lastly would you then extract with acidic rinse??
I personally havent had to clean anything with this problem and would unless totally confident avoid it, but it would be good to know whats best.
Thanks Paul

Hi Guys
Why mix a micro-spotter when you already have a Woolsafe approved acidic micro-splitter available.. I refer to One-Step Fineline
As John has said ...a little lateral thinking ;)
Derek
-
Didnt realise there was sush a thing ???
Until now!!
Thought Fine Line was pH neutral.
Paul
-
Paul,
There are many dye stabilisers that can be used - as I said the pH is not always the the critical factor at this stage though indeed most modern vagrant dyes will stabilise at the low end of the pH scale.
You have largely grasped the principal but the final stabiliser would normally be simply sprayed on. however I have cleaned items that required different stabilisers for different colours - in these cases the stabilisers would normally be applied before and after with a small stencil brush.
-
Thanks John, This type of work with very unstable dies on valuable items i think i'll continue to avoid as it sounds beyond me at the moment, i only take on work that i'm at least 99% sure of what i'm doing!
Although if you know of a training course which covers the techniques you have mentioned i would be keen on attending it.

As Big Brother has said the different colours react in different ways and tests should be carried out at points stages throughout the rug ... a good guide is the 'abrash' that can be seen on most hand made rugs
Abrash...colour shade changes due to a change of dyed yarn during the making of the rug
I have successfully cleaned a few real 'bleeders' in my time so much so that when colours have been tested post clean they have been less fugitive that beforehand.
Of course if you are unsure then you should walk away that is the correct thing to do...sometimes some of us like to live a little dangerously... if it goes wrong then you are in big trouble.
We are not just carpet cleaners ..WE ARE IN THE RISK BUSINESS
You recognise the risk, you minimise or remove the risk if this can't be done then walk...

Wise words :) I could do without any extra stress (got enough of that already :-[) so i'll leave this kind of thing to you guys living on the edge ;)
Thanks Paul
-
At our (my) age Derek, I find it ?? stimulating??, exciting??, to live life on the edge a bit.
What say you & John, oh, and Len??
Cheers,
Shorty.

Shorty,
I find that jumping out of planes or abseiling from great heights cannot match the adrenaline rush that comes from cleaning an antique tapestry - one drip away from disaster.
I suppose it's a bit like bomb disposal, except when they make a mistake nobody claims for a new bomb ;D
John.
