Hiya,

Quick question I understand that Hydrogen Peroxide is accelerated with Ammonia and Sodium Metabisulphite with Acetic Acid. 

My question is in the real world of stain removal what is the process of applying the accelerators to the stains.  i.e. do you apply the Hydrogen P and then add the Ammonia ore apply the hydrogen p, rinse then apply Ammonia.  The later does not seem right to me.

Any help greatly appreciated.

Any help with this please

Darren, the best accelerator for Hydrogen Peroxide is heat. Either a hot steam iron applied through a wet terry towel or better a hair dryer.
You can mix it with Ammonia but you need to be careful. If the concentration of Peroxide is too high you can get a lot of uncontrollable heat generated. Also Ammonia can Yellow Wool.
Not sure about using Acetic with Sodium Metabisulphite but again this can be accelerated by using a hot steam iron over a "wet" not damp terry towel.

Hi Darren,

You are right in your way of thinking.

Hey Colin

I see you have been eating too many sticky buns and drinking too much cappacino again sunshine 

About time you started cleaning a few 'real' carpets!

Cheers

Hi,

Acellarators / catalysts chemically change the bleach you are using.  Basically, you form some new more powerful bleach and therefore you should premix the solutions in appropriate quantities.  How much you use depends on concentration of stock solutions and often depends on pH.

As a rule you want to make a solution of peroxide pH > 7 and sulfates/ites <7.

Beware of playing with reducing bleaches though as they are tricky/nasty/smelly and hard to control.
