F90 is the best selling detergent!
It has several dilution ratios, one being wool safe

[Simon Gerrard]

We use SPM on the vast majority of domestics and rarely agitate it. I think this agitation, dwell time thing is a bit of a myth with ms's.

[john martin]

is it simular to prochem crystal green or more advanced than that?

F90 would be similar to crystal green .

They both contain  ... washing soda ( sodium carbonate )
                                   Alcohol Ethoxylates
                                   EDTA

F90 has some orange oil  ( d-limonene )  also .


Steve . I mostly use the Chemspec range as its easy for me to get .

Crystal green is a pre-spray.

[Simon Gerrard]

We use twin vac portables on certain jobs, some of them mingers in high rises and get great results every time without agitation. Warm / hot presprays do just as good a job at breaking up the soil.

No it's not, it's a rinse agent.

I think most of these products can be both unless its a very high ph product that might not be suitable as a rince .

Probably should distinguish the rince purpose .
A cleaning rince i think the OP refers too  , thats up to the user  , personally i prespray and  stick a bit in the tank  .

As distinct from a specific rince product like an acid rince or something like liquid high heat that has some surfactant , acid and anti soiling polymers .

F90 might not be woolsafe approved but i think its fine at high dilution ratios .

[jim mca]

If formula 90 powder was safe for wool then chemspec would have paid for the endorsement the same as they have with the liquid version

[Carpet Dawg]

wool safe or not wool safe its a load of old cobblers.

I've been doing this thing for over 13 years and been using formula90 almost from day one. Never had a problem, knackard carpet or other wise. 1000s of carpets cleaned in that time.

I did turn a stain green once using "spray and go", apart from that everything has been golden.

[Carpet Dawg]

Its well known that the wool safe organisation has given Vanish the seal of approval.

what ever prespray you are using it is a big benefit to agitate it can only break down soil that they come into contact with, so need to be dispersed throughout the pile.  Prespraying carpets is not a new thing it is something that I learnt on my first training course over 30 years ago.
There are still people operating out there without the knowledge of their existence.
Training is important. I know from experience that it takes no longer and will probably save time in the long run. The results are much better and for anybody using a truckmount you are going to use a lot less fuel if you use a battery sprayer.
If you do not agitate then go out with somebody that does and compare the results.
If you have nothing to compare something with it is very easy to convince yourself that you are getting the best results.

i do like spm but i have noticed that after a decent dwell and agitation,any sortof black grease based spots dont seem to move,i tend to give them a blast of multi pro ,brushed in then extract with my tm
multi pro doesnt seem to get much attentiom on this forum ,i used it for 25 years,its simply brilliant  !!!!
in my humble

It may come as a shock to some people but chemicals don't stand still . I have seen products described as old fashioned. What garbage. The main suppliers are continually re-formulating the range. We have monthly updates with changes to msds as the products change and update.

[ian harper]

detergents are far more advanced and have lots of additives, with the different types amphoteric, cationic, non-ionic, anionic. each dealing with different situations.

Totally agree with you John but there are also a lot of new kids on the block that try to convince they have invented the wheel.
