Ask a carpet cleaner what actually moves the needle on a soiled traffic lane and the answer is almost never the wand. It is what went down before the wand, and how long it was left to work. Suspend is a concentrated preconditioner built for that job: it goes down on the heavy lanes, breaks the greasy binder holding soil to the fiber, and hands the extractor a much easier problem. It is Carpet and Rug Institute certified as a premium carpet preconditioner, and it is sold here as a case of four one-gallon bottles.
Built for
- Residential carpet cleaners working kitchens, hallways, and stair traffic lanes.
- Apartment turn crews facing heavily soiled units on a tight schedule.
- Commercial route work in offices, corridors, and food service areas.
- Restoration crews preconditioning before a deep extraction pass.
- Owner-operators who want one prespray that covers most synthetic carpet calls.
How it works on real soil
Suspend combines softeners, grease lifters, and surfactants, which is why it handles the mixed soil load that shows up in the real world rather than just one category. Animal, vegetable, and petroleum oils, cooking residue, and food soils all release rather than smear. It is low foaming and easy rinsing, which matters if you are running a truckmount and do not want foam in the recovery tank or residue left behind to re-soil in three weeks. The finished traffic areas carry a mint fragrance.
Dwell time is the part professionals argue about and the part that decides the result. The working consensus among production cleaners is that a prespray needs roughly ten minutes of contact time, that ten to fifteen minutes is the productive window, and that going much beyond that adds little except the risk of the prespray drying on the fiber. The efficient rhythm is to prespray in sections and come back to extract, so the chemistry is always working while you are moving. Cleaners who do this consistently report the same thing: soil emulsifies so thoroughly that the carpet looks better and the wand pulls easier.
Dilution and coverage
Suspend dilutes at 1:45, which works out to roughly 2 and three-quarter ounces of concentrate per gallon of warm to hot water in a pump-up or power sprayer. At that rate a single gallon makes on the order of 45 gallons of ready-to-use solution, so a four-gallon case covers a great deal of route work. Diluted pH is 9.2. That alkalinity is what makes it effective on greasy traffic lane soil, and it is also why wool and delicate natural fibers should be cleaned with a dedicated wool-safe preconditioner instead. Suspend meets specifications for use on stain-resistant carpets. Always test in an inconspicuous area first.

Frequently asked questions
How do I dilute Suspend?
Suspend dilutes at 1:45, which is roughly 2 and three-quarter ounces of concentrate per gallon of warm to hot water in a pump-up or power sprayer.
How long should I let it dwell?
Around ten minutes of contact time is the usual target, with ten to fifteen minutes being the productive window. Prespray in sections and return to extract so the product is always working.
Is it safe on stain-resistant carpet?
Yes. Suspend meets specifications for use on stain-resistant carpets. Test an inconspicuous area first as you would with any preconditioner.
Can I use it on wool?
Diluted pH is 9.2, which is more alkaline than wool and delicate natural fibers tolerate well. Use a dedicated wool-safe preconditioner for those fibers.
How much ready-to-use solution does a case make?
At the 1:45 dilution, each gallon yields on the order of 45 gallons of ready-to-use solution, so a four-gallon case goes a long way on route work.
Will it foam in my truckmount recovery tank?
It is formulated to be low foaming and easy rinsing, which is why it is commonly run with truckmount and portable extraction systems.
