for those of you who clean cars professionally, such as myself, one thing you might use occasionally is carpet and fabric dyes. now the aerosol cans of various brands tend to get the job done but they are not very cheap ($7-12 a can). I learned years ago that you can buy a box of the powdered RIT dye, most people use it for tie-dyeing, and mix it with water to make LOTS of dye for less than $3. on their website they sell many different colors, similar to the aerosol dyes. browns, greys, blues, reds, and obviously black is easy to match or at least make look a whole lot better. so, when you cant get the carpet cleaned as well as you would like just spray a bit over the top and it all blends in . also, occasionally we get vehicles in that have had bleach spilled on the floor and you can really work miracles with the RIT on those jobs. just a thought.
Many years ago, I used to do business with a Wax Factory on 38th Place near Ashland Ave in Chicago called Nu Look.
Of the too numerous to list products they manufactured, one was a combination Carpet Dye and Shampoo Product. They made it in a variety of colors.
At the time, I owned a 1968 SS396 Camaro, Lemans Blue, with Black and Houndstooth Interior.
While the person I bought the car from said the Carpet was recently replaced, otherwise all original interior, the Carpet, and the Seat Belts were both a bit faded.
I discussed the issue with the owner of Nu Look, and he right then and there mixed me a qt bottle of the product. What was in it, I have no idea, and I did not get to see what went into this product? All I know, was the qt bottle was quite hot.
He assured me no bleeding, that it was permanent, and told me how to use it.
Out of some aprehension I only did the carpeting first. Apply with a damp sponge wearing rubber gloves, let dry, vacuum. There was no bleed, so I did proceed to do the Seat Belts, avoiding the stitched on White Seatbelt Tags. Both the Belts, and the Carpets had a like new look, not dulled, or chaulky looking at all.
Now whether this product was simply a Rit Dye, added to a Carpet-Upholstery Shampoo Mixture I honestly cannot say?
This might be interesting to further investigate, if there are products-dyes that are of an industrial grade, that would not have a tendency to ever bleed-come off?
