Top-loading washing machines are much easier to use for dyeing, because the lid can be opened at any time during the cycle, and dyes or auxiliaries can be added at will. Front-loading washing machines are much more frugal with water, however. Some front-loading washing machines, particularly in Europe, have heaters which allow fabric to be dyed or washed at temperatures much higher than tap water can reach. The best front-loaders for washing have dispensers through which dye and auxiliaries (such as salt and soda ash) can be added, taking care of the major problem of not being able to open the front door during a wash cycle. If your front-loading washing machine lacks these dispensers, try Dylan Machine Dye, if you can get it, as the instructions for its use do not require them. The ideal small dyeing studio should have both a top-loading washing machine, for use in dyeing, and a front-loading washing machine, for use in washing out dye. If you have a top-loading machine that still works, but wish to replace it with a front loader, consider keeping the top-loader, and stacking a new front-loader on top of your dryer, or underneath it.
