Pre-Spray vs. Detergent in Tank

Presray the entire room.
commercial - I use a Hydroforce sprayer with hot prespray.
residential - good pump-up sprayer with hot prespray. If it is a large open area, then I use the Hydroforce.

I rinse commercial with 9.5 ph mix, then fabset.
I rinse residential with emulsifier/low ph rinse to bring carpet to neutral ph. If the carpet is berber or conditions won't allow it to dry fast enough, I fab set.

You have to rember that a chemical injection sprayer will not syphon with tempratures over 60 c

Wow ! We hydroforce using Energiser, Attack or Enzal w/deoderizer then rinse with Performance CBS.
After reading this might start using just water to rinse. Curious how much money we would save in the course of lets say one month.
If you think about it I am sure it has happened to everyone here where you forgot to turn the chemical back on after the prespray and was still impressed by your performance.

I use my Hydro Force and pre spray all the carpet. If you heat your pre spray it makes the soap molecules more active. Their used to be a rule of 18. Once you hit 118 degrees the ability of the soap to cleans doubles for every 18 degrees hotter.If you use a slightly acidic water rinse it will leave the carpets softer and keep you from having PH browning. It was a long time ago when I heard that, probably twenty years or so.

i switched to pro-max for my emulsifier and it still leaves the carpet soft and I never have browning. I meter it according to the job difficulty and have been very pleased ever since. A little pricey, but a great product.
