Out of curiosity some of us who use bed bags under the wheelchair etc .... Sediment seems to sort of build a whitish crust inside the clear plastic hoses

This is not a gunk or uti
It is more a mineral whitish particulate is the best way to describe it .
I use a fresh bag weekly to avoid this but it is just mind boggling as to how these gritty things stick inside these pvc hoses
( I think the plastic hose is PVC)

I flush clean the bag every day and still some form of whitish calcification will stick inside somewhere .
What type of tips / tricks do other folk here utilize because these bags are fairly costly when you look at the overall picture .

Topic wise I know this has been mentioned before but lately it seems that more people have been noticing sediment / stuff in their bed bag hoses .

Anyway everyone have a good weekend and thank you
