I've been doing this for almost 40 years now. At one time we didn't prespray, just used an emulsifier. Then presprays appeared and we did both. Then we just water rinsed, then we acid rinsed. All the time manufacturers were changing their formulas to meet the needs of the carpet manufacturers. I have seen the difference in all of these methods and for my money, the best combo is a prespray designed for the job at hand followed by an alkaline rinsed. The biggest problem with water rinsing is if the carpet is not coming clean enough, you have to stop what you are doing, re prespray the area and cleaning it again. If you had a good alkaline detergent metered through the truck, you usually need to hit again or more slowly and it will come out. I used to work for a company that water rinsed and hated it.for what its worth, heres my take.
1. Dilution ratios for presprays from the manufacturer dont take into account using a CRB or other mechanical agitation. That being said, it is perfectly logical that you can dilute prespray even further IF you use a CRB (not to save money - you just dont need it). Yes, on rat nasties you can boost it as needed, but for most cleaning a reduced dilution works just fine.
2. if you arent using that much cleaning agent, your rinse is much more effective.
based on the above 2 assumptions (im not a chemist) although reluctant, I did try rinsing with water only about 10 years back. Not only did I find that the carpet came just as clean with water only as with a rinse but (and much more important) when I came back for future cleanings the carpet was not as dirty as it normally was. Most of my customers clean at regular intervals so this was easy to see but again not scientific.
I was so convinced that when it came time to replace a water pump, I never even added the chem pump to it because I preferred using water rinse only (softener required)
Cheap assOn a group text.
These guys are stuck on the old "alkaline prespray, acid rinse" rule of thumb on their synthetic carpet, they're scared to use just water. They'd rather waste money on chemicals not needed and have that piece of mind thinking that the carpet won't be stiff. I'm sure they're lurking on here, so someone tell them that just rinsing properly with hot water will make that carpet come out just as soft and clean as using an acid rinse.
Keep in mind, they're using a ph product of around 10.5 I think, and they are out west, so I'm sure a water softener is needed. So I'm just saying that normal water, preferrably soft on their dirt, will do just fine and save chemical cost. And won't wick back if it's fully rinsed. It can possibly wick back if it's down in the pad, but using a acid rinse or plain water won't make any difference.
I'm blowing this out of proportion, but if bugs the s*** out of me, because they're trying to make me look like a moron.
So fellow 1-3%er Mikeyboarders...show your knowledge.
My main argument was them telling me I was a dumbass because I told him that his acid rinse was not needed on that situation and water was just as good and alkaline rinse was better.Pre spray what works best for the carpet your cleaning, rinse with last step. It super
however...the fact remains that you are STILL a dumbass........yor lik a windmil....whichever the wind blows...there goes Matt Wood!!!My main argument was them telling me I was a dumbass because I told him that his acid rinse was not needed on that situation and water was just as good and alkaline rinse was better.
My point on wasting money was the fact that he was wasting it on the acid rinse. I have both my rinse jugs (alkaline, and acid) used regularly, and I use plain water when I feel they're not needed.
Me no cheapskate
Funny how it goes differently for different folks......... although reluctant, I did try rinsing with water only about 10 years back. Not only did I find that the carpet came just as clean with water only as with a rinse but (and much more important) when I came back for future cleanings the carpet was not as dirty as it normally was.
