Title: Formula 90
Post by: paul searle on February 22, 2013, 06:48:49 pm

I've been trying out different chemicals & manufacturers lately & just had a question about chemspec formula 90. Basically if this is a rinse detergent how can it have a ph level of 10-11 surely this will leave the carpet a high alkaline.

Have I missed something here, advise please

When you dilute liquid formula 90 it lowers the ph level

Paul

Are you talking about Formula 90 liquid or powder?

Its buffered so its self neutralizing once its drys.

Have always used the liquid are they any big difference using the powder was thinking about trying the powder with the truckmount.

As above, it is buffered so it self neautralizes once dry.

all chemicals self neutralise when dry as 'dry' does not have a Ph value but what would happen if you got out of the bath & walked across the carpet with bare wet feet would the wetness reactivate the residue and PH ? :o :o :o

How much chemical is actually left in the carpet once you've finished???

With Formula 90 crystallizing I always advise a thorough vacuum once the carpet is dry to hopefully remove what is left.

I could be wrong here but I always thought Formula 90 was buffered so that it maintains its ph through different dilutions.

Thats right Karl, Non buffered chemicals dont hold there PH value but buffered do! most of chemspec products including formula 90 are christaline when dry and are vacumes away
Only formula 90 liquid is different, the more you dilute the lower the ph hence if you dilute at nearly 1000 to 1 it becomes woolsafe

I've found this to be different, when I dilute f90 powder less the ph does lower.

Dont know what you are using Shaun, but Chemspec did a demo not long ago at a woolsafe training day showing you couldn't dilute ph on formula 90 powder

I dilute it at approx a quarter of suggested ration and when I checked the ph it was lower than stated on the tub, I haven't done it for some time so I can't remember what ph is was but definitely lower.

Maybe it has somthing to do with your chemical meetering ? ie truckmount!
