Will my clothes shrink at 40 degrees? Generally, at 40°F, most fabrics or weaves don't shrink. At 40°C many fabrics or weaves are at risk of losing integrity. Most washing machines agitate too harshly on hot for loose weaves and many “natural” (non-petroleum-based) fabrics.

Is 40 degrees too hot for clothes?

A warmer wash is better at removing tougher, heavier stains that are harder to get rid of. Generally 40°C and above can be classed as a warm wash and most clothing can be washed at these temperatures.

What temperature will shrink clothes?
