Mike , is it possible your results are a bit dull because of the MS. So people don't get back to u . Perhaps some good chemicals, more repeats, you won't have to go leafleting .
John You might be right
Ned your post show you definitely are not a chemist and using the washing machine example shows a very limited understanding of cleaning chemistry, you will use the ‘washing your hair’ analogy next
Let’s start at the beginning and answer the question at the very beginning of this post, why not use a formula90 (a detergent) as a Pre-spray.
What is the basic difference between a pre-spray and a detergent? One is designed to be left on a carpet the other is designed to be removed.
A pre-spray has chemicals within its make up that cannot be left on a carpet, pre-sprays are meant to be rinsed off the carpet because of this they can contain more active, aggressive chemicals. They should when used correctly not come in contact with the homeowner.
Detergents are the opposite, they are designed to be harmless and because we never recover 100% of the solution we use they will be left on the carpet and come into contact with whoever uses the carpet ( the homeowners, small children, pets etc..etc) this is why detergents will never be as effective as dedicated pre-sprays they cannot contain anything that is harmful or causes the carpet to re-soil quicker.
So detergent is ok to be left on the carpet pre-sprays have to be removedcan anyone tell me that they remove 100% of the pre-spray they put on the carpet? And if so how do they know? Do people think that going across a carpet with a wand spraying an acid rinse or formula 90 actually removes all the pre-spray they put down? I’ve seen carpet cleaners using a Hydraforce putting massive amounts of pre-spray on a carpet no way are they rinsing it all out. So most carpet cleaners leave a massive cocktail of chemicals on the customers carpet not only pre-spray but they spray a load of detergent on as well
leaving the carpet a virtual cesspit of carcinogenic chemicals! So what if you use a pre-spray that is perfectly harmless if doesn’t get completely removed, that is perfectly safe to leave on the carpet? Would this not be better?
Now imagine if during the in-house quote you explain to a potential homeowner what I have just typed above asking them what they would prefer.
