If you have a suede piece that is ready to be thrown out because it`s been faded or stained,
then it can`t hurt to try to dye it.
I did this yesterday with a 1960s suede coat I inherited from my great-aunt.
It had been lavender but had faded so that parts of it looked grey-green.
Having nothing to lose but $12.00 for three bottles of Rit Dye,
I soaked the coat in water until it was thoroughly wet.
Then I placed a large plastic storage bin in the bathtub,
added three bottles of Rit Dye and enough hot water to cover the coat.
I mixed the dye and water well,
and then added the coat.
The dye will take immediately but move it around in the water with gloved hands for as long as a hour.
I probably should have left it in longer than 15 minutes but it turned out a lovely dark shade of red-violet,
The only downside it that it is messy and takes a long time to rinse out.
If I had a backyard,
I`d do it there and use a hose to rinse.
The odd thing is that last summer,
when I washed the coat,
it shrunk up to where it was almost unwearable.
I removed the lining.
When the coat dried,
I found that it had returned to its normal size,
and maybe even a little larger.
I think the dye relaxed the suede.
Note that it will stiffen up when it dried,
so you`ll want to rub the suede between your hands to relax it.
Note that some tubs can be permanently dyed so be careful where you do it and use a cleaner with bleach for cleanup (I used Ajax with bleach and it took care of it in a minute or two).
I also used the same tub of dye to dye a 1930s silk velvet dress and that came out beautifully,
so Rit is very versatile.
