If there is half a chance, do it in the bathroom rather than the kitchen. Practically all of the darkroom chemistry is toxic, and that doesn't go too well with the food handled in the kitchen. You may do as much cleaning as you can, you can't fully avoid contamination of surfaces which might later get in touch with your food. You might consider covering everything with plastic sheets, but the necessary cleaning and clearing up will then take a lot of time, time not available for darkroom work.(posted 8892 days ago)
