Steve,
I have yet to go back to a job to post vac, when surveying i stress to the custy of the importance of this part of the process , i ask on what regularity the floors are normally vacuumed and by whom, usually they will have in house cleaners and if it is not on their schedule to vac every day they will make a point of ensuring it is done the next day, although a pre vac is often done before i get there ,I do prevac myself.
I would suggest sticking to cimex encap solution, but do wish others were available dilution rate 16 -1
often a good idea to add a water softner tablet if in hard water area. the optimum results are achieved by creating a thin even layer of foam , this is achieved by pushing forward realisng the fluid and pulling back over the area just covered at a slow walking pace, to slow and to much foam is created, on area,s not badly soiled you can release the solution in bursts pulling the trigger on and off there fore saving solution and money, this is not cutting corners it is recommended by cimex , in badly stained areas do not be tempted to add more solution, simply go over the area with dry passses and for bad spots etc cimex do have an encap spotting solution, pretty good too.
normaly the carpet is ready for a vac the next day, this gives the chance for the chrytalisation and encapsulation to work.
Hope this helps
geoff
