I observed a post on RV.Net regarding an RV'er who dyed his motorhome carpet because of age and wear. Ten days ago, I did the same thing using RIT Dye (Royal Blue), a hand-operated plastic spray bottle and a soft bristle bush to work the dye "in." I, first vacuumed thoroughly and then rented a rug cleaner machine (Rug Doctor) from a Lowes Home Improvement store. On my hands and knees, I sprayed every inch of the carpet and worked the dye in with the bristle brush. The 1st day, I used 9 boxes of RIT Dye (mixed with hot water). Suggestion: if you have white sinks, don't work in your sink
. No matter how good you clean, there will be some residue that you will miss
. I found the outside hot water shower connection (with sprayhead removed) worked best
. I put the overhead fans on and let it dry for two days, actually, it takes only 24 hours, but I gave it the extra time. I then used another 7 boxes of dye making the rug darker and more "even" in color. Oh, gloves are highly recommended
. The only places that I masked off were the fabric / cloth areas. Everywhere else, wood trim, vinyl, tile, I wiped immediately with a wet paper towel or cloth and the dye came off clean. This rug dye "fix" may not be for everyone. The RIT people recommend not dying rugs. This product is for dyeing cloth, etc. and to be washed again afterward to get all remaining dye out. Another RV'er recommended to lightly shampoo your carpet after dyeing, I have not yet done this and may not, period. I am leaving on a 4 month trip shortly and will see how it dries and wears.
Right now, the wife and I are happy with the much improved appearance of our carpeting. Initially, I think we'll be careful to ensure our stepping out of the shower onto a shower rug and not onto the carpet, hence "blue" underside feet!
Stay tuned for an update "down the road a piece."
