@kitten@theking generally the detergent and heat is just very not great
leather straps would fair the worst obv
nylon and fabric could survive it, but the heat could get them twisted or similar deformations, and the heat and detergent could also cause the color to fade
metal straps by themselves might be fine for some metals, but they may have a coating or similar that can't withstand it as easily, and it would cause it to be damaged
rubber would probs be mostly fine, or at least better than other materials, but over time it could still cause it to crack or lose elasticity etc
silicone should be mostly fine, and should not have any major issues, however color and finish may still change
either way, ur risking changing the finish, color, durability and so forth by putting them in there
