What is the best way to dye a red sofa cover brown at home?

Answer 1

The best way is to first weigh your sofa into managable batches that will fit into your washing machine. Ideally each batch the same weight. Try not to have your drum more than half full to avoid patchy results.

I would recommend stripping the red colour out with a dye striping agent (not bleach this will rot the fabric). This will not only prepare the colour base but will help remove any finishes or stains that may interfere with the dye uptake.

when it comes to the dyeing, weight the dye for each part out so that you have the same % of dye to weight for each batch.

Dylon supply the dyes and dye stripping agents also there are companies that specialise in doing this just google sofa cover dyers.
