Hello
I have an American Standard (home depot brand) kitchen faucet from 2011. The hot and cold water supply line hoses are falling apart. The outside silver/grey layer has turned brown and flakes off. In the attached picture you can see the underneath whitengut of the hose, which looks ready to burst.
I'm trying to figure out what caused that, and I can only think that it was caused by vapors of chemicals stored in that same cabinet. Under the sink we have the usual stuff
- Dish detergent,
- CLR,
- Potatoes and onions in a bin,
- Windex
This can't be caused by the water itself; you can see the supply line to the removable faucet is perfectly fine in the picture (silver). Why didnt that one turn brown and peel off?
I have a replacement faucet coming and the supply line to the dishwasher is starting to brown out. Does anyone have any thoughts as to what may have caused hoses 3 years old to look like they are 30 years old?

Might not be, but looks like, effects of sulfur out-gassing from drywall.
See https://en.wikipedia.org/wiki/Chinese_drywall or Google 'Knauf Plasterboard Tianjin Co.'. Drywall commonly emits sulfur gas, however some of the lots from China were apparently really bad. The bad drywall was widely distributed, including at Home Depot.
Note: A lot of Home Depot Quality 'stainless steel' is not very stainless. But your picture shows a situation well beyond that. Everything under that sink looks 50 years old: note the corrosion on the pipes and valves as well.
