-This person told me that chlorine is used to give brightness to the colors.It's correct?They are used both in the finishing washing of new rugs to tone down color and to control/correct dye migration during a normal wash. It is normal practice throughout the industry to use both sodium hydrosulfite and chlorine bleach.
Fantastic!Hydrosulfite can be used alone however chlorine bleach is neutralized by the hydrosulfite (among other possible neutralizers). So if you are using chlorine bleach you can follow up with hydrosulfite once desired results are reached to stop the chlorine bleaching effect. Hydrosulfite is neutralized by cold water and rinsing.
Hydrosulfite can be mixed at many dilutions however a good starting point is roughly .5oz to 1 gallon of hot water. Baking soda can be added to lessen the strong odor, usually 1/3 of how much hydrosulfite was used will do the trick. Working with hydrosulfite without baking soda is almost unbearable, be sure to have plenty of ventilation during and after use.
For bleach generally a starting point is a cup of 6% available chlorine bleach to 5 gallons of warm water, followed by a dilution of hydrosulfite to stop the reaction.
We find that a light hydrosulfite strip can brighten colors, we do not use very much chlorine bleach so I cannot speak to it's uses in this way.
Others may chime in to fill in the gaps in my explanations here, this is just as I understand it.
GREAT!Dwell time depends how much color you have to remove vs how much adverse effects you're ok with. This is less science and more art at this point. Try it out on some scraps you own first. It can take a while to get the hang of how these chemicals work.
There's nothing mystical about trial and error, how do you think it was learned originally? Buy some crappy rugs and play with it, find the limits and take notes along the way. I'd be weary of a rug washer that isn't willing to figure out how to use these chemicals, there's a much higher chance they're the ones ruining the rugs.They would learn the process from experienced rug washers not on their own. Knowledge is passed on from one generation to another. I am not sure how many rugs you would ruin before you had learned the proper procedures along with the chemistry. Be wary of trying this on your own!!
No they are not.Google helps me. ahah
These 2 chemical products are samething?
Probably not. I don't think they're silly enough to believe that as "pet parents" their pets should be treated like pampered children.I wonder if rug washers on the other side of the pond have to deal with as much pet pee as we do?
