I have old fashion teat cups. (I'm not sure if that's the right name.) I'm talking about the part that is stainless steel on the outside and black rubber on the inside. They seem heavy. Is the weight an issue on teat health? Can I remove the middle rubber section from the outer stainless part? I've given it a tug, but am afraid of damaging it. Although I rinse my hoses after each use, I am noticing some small spots of mold. Can I soak the hoses in bleach water? Any other suggestions? I bought a wagon to pull my surge bucket to and from the barn. That thing is so heavy even b4 the milk is in it. Do any of you do that or something similar? Thanx for the input; even if it's about something I didn't mention.
