    If the product requires 1oz for 5 gallons to make a "ready to use" solution, how many ounces in a Hydroforce 5 quart jug with yellow tip metering at (1:8) Dilution?
    The product I am trying for the hydroforce is Prochem's "Dry Slurry"

    The dry slurry is asking for me to use 1/5 as much product as the cheaper Matrix Powder.
    I dont know if it works better or not yet. Still experimenting.

    Mathmatically it works out to 1.6 scoops ( I think!)
    So, 2 scoops would be ok?

    My current powder states roughly 1 oz per gallon finished product, so I put 8 scoops in the hydroforce. Which is diluting 1:8

    Richard, Dry Slurry is normally used as an extraction product. That is to be used in your rinse through your solution line. So it would not be applied with the HydroForce spryaer as a prespray.

    The Dry Slurry ends up being diluted at 400 to 1 when used as directed in your rinse. Great dilution for a rinse, but it would not give you much as a prespray.

    If you want to use it as a prespray, you may want to experiment to find the right amount or contact Prochem for their suggestions.

    I use Dry Slurry as a rinse. It says 3 cups to five gallons. I use half that and it works wonders with my prespray. I feel 3 cups is WAY to much.

    Dry Slurry is an extraction detergent powder. I understand they were designed to be used with the chemical feed in the truckmount, but I have issues with this, and prefer to rinse with clear, soft water. Using detergents in the chemical feed not only defeats the purpose of rinsing, but contributes to cloggage and buildup in your chemical feed system, hoses and nozzles. How can you rinse out soap with soap? This is why "rentals" do so poorly, they do the same thing.

    For the past several years I've been using Matrix Extraction detergent powder and it works great as a prespray, even with lower temperatures and a portable.
    I've used other brands of extraction detergent powder the same way, all with good results and properly rinsed carpet.

    I have found with a few products now, that extraction detergent powder makes a great prespray, far outperforming all of the "prespray" presprays.

    Nonetheless, it is still a PH 9.5-9.9 detergent spray when mixed properly and does break down and emulsify dirt quite nicely.


    Sooooo, does anyone know the right amount to put in the hydroforce?

    You are in uncharted territory.

    Since you are using a detergent as a prespray I would say you are going to have to try some different dilutions and see what works. Of course, the more you put in the more rinsing it's going to take. Try 2 scoops and see if it gives good results. If not, try 3 scoops. From what I've heard about dry slurry it's a good extraction detergent. I am wondering though why you don't use any kind of regular TLC, even a green, earth friendly one, or low VOC? I've used a lot of Matrix Finish First myself, but never as a TLC and I have serious doubts it would perform well in severe soil such as trashed out rentals, greasy restaurants, etc. Do you use other products in those situations?

    If you want to achieve the same dilution as when used for an extraction rinse, it would take 2.25 oz. in a 5 quart 8:1 sprayer. What everyone is saying (and I agree) is that to use it as a prespray you will want a much stronger mix. You will have to experiment to determine how much.

    Its easier for me to figure in quarts, since the Hydroforce is measured in quarts. The normal dilution is 1 oz per 5 gallons RTU. If you spray 5 gallons out of a Hydroforce (20 quarts) 17.78 of the quarts will come from the water supply :)8) and 2.22 quarts will come from the jug (1: ). So, you need 1 oz. of chemical for every 2.22 quarts in the jug. 5/2.22 = 2.25.

    Clear as mud?

    Oh, and to get a true 1 oz per gallon ratio on your current prespray would require 11.25 scoops per 5 quarts in the hydroforce. Think of it this way: in order to empty the jug (5 qt), you have to push 8 times as much water (8 * 5 = 40 qt) through the water supply. Thats a total of (40 + 5) 45 quarts of water sprayed, or 11.25 gallons, so you need 11.25 scoops of chem.

    All this assumes the Hydroforce really meters at 8:1 which is, of course, pure fantasy...

    I agree with your strategy, I was thinking three scoops for the hydroforce and see how it goes. With Matrix Im currently putting in 8 scoops, but I wonder IF I should back it off a bit. It's asking for around 1 scoop to a gallon if mixed in a pumpup.

    As for your other question, in extreme soil or staining conditions I use other stuff. Matrix prespray is boosted with a little Citrus Sol as well for degreasing properties. Under normal conditions it works fine, is practically odorless except for a slight lemony scent, and is reasonably safe for handling and breathing, skin contact, evironmental etc (see msds)

    Im having issues with regular presprays, they dont perform, they are generally fumy too. Soap free presprays work pretty good for me since I have good heat, but not the most cost effective and I like to "explore uncharted territory" as you put it. :)

    Trashed out rentals = Regular prespray with Citrus Sol, followed by Traffic Slam (Bridgepoint) for a second round in the stained areas.

    Restaraunts = Powdered Enzyme with Citrus Sol. I did some research, the Citrus Sol doesnt appear to harm the enzymes.
    Use scrubber if its real bad, clean twice to avoid streaking.

    LoL I agree... fantasy I have yet to try the bucket test, perhaps on a warm Saturday afternoon when I have no work and nothing else to do, which will be.. um... sometime.

    Wow 11+ scoops! I thought I was mixing it a bit strong already at 8 scoops! Too much powder in there and the stuff just gets "gunky" and slimes up and clogs everything. But if 11 scoops will give a closer "1 scoop per gallon" on the floor then I'll stick with 8 scoops if Im using matrix.

    Now, looking at your calculations for the 1:32 dilution of the dry slurry, assuming your correct, means I only need about 3 scoops max for the hydroforce, hence why I want to try dry slurry and see if it performs. I'll post later on what I think of it!

    The Matrix only costs about $20 for an 8lb container
    The Dry Slurry is more per keg, I dont know how much yet,
    havent got the bill, but the point is Im using less than half as
    much product so It should be more cost effective. PLUS I dont have to get it shipped over the border and will save brokerage and shipping costs.


    Side note for others reading this! I dont want to hear about how chems are only 2% of your expense to run the business and bla bla bla because for my business chems are a major expense and the whole theory about chems being cheap was cooked up by suppliers so they can feel justified raising the prices every three months.
