Back in the 1960's, once carpet was first cleaned expertly, the only method available was shampooing. The guy would come in with his rotary scrubber, spray shampoo on the carpet, rinse it in and then leave. He left instructions to await until it was dry, then you certainly were to vacuum it. The PH of the shampoo used back then was high. PH refers to how acidic or alkaline a liquid is going to be. For example , water is 7, which is neutral. When the flooring dried and was cleaned, a lot of the shampoo would be in the carpet. This wash then acted as a magnetic and would quickly yank dirt to itself coming from foot traffic. Can you guess what happened? The carpet would get smudged fast! Even when hot water removal came out (steam cleaning), the cleaning solutions were also very alkaline and attracted dirt to the carpet quickly. Nowadays, the solutions that carpet cleaners apply (even the shampoos) TYPICALLY attract dirt. My maintenance company, like many, works with a solution that has a 7. your five PH, or close to that. It's slightly alkaline only because soil tends to be slightly acidic, thereby leaving a simple solution to dry out of the floor. But here's what still takes place now because of the old belief. You wait until your floor covering looks really dirty ahead of getting it cleaned for the first time. Well, the carpet is kind of like a wastebasket, except that this fills up with dirt from your top down, instead the bottom up. So if a professional cleaner can come in and tidy before the carpet is totally complete, a much higher percentage, in cases where not all, of the dirt can be taken off. But if you wait until the rugs is completely full of soil, afterward even the best cleaner near your vicinity (that's right, me again) can't get it all out. Although here's the trick-it'll GLANCE clean. However , since will be certainly still soil in the floor, guess what? The carpet gets full sooner, and generally seems to get dirty faster! In essence this myth becomes self-fulfilling.
