I am stocked up but still adding more.
I have two storage 10x20 where I store stuff I don’t room for and a section in both that is strictly for prep. They are 50 miles apart, so I should be able to reach at least one if have to.
I am stocked for 3 months to support 4 people at my office.
At home I have somewhere between 9 months and a year worth of everything except TP, though we have plenty of that and cut shop towels into wipe sizes. Just need to setup a system for disposal and cleaning of them if that time comes but, I grew in the diaper age and know what to do.
Part of anyone’s prep should be bathroom gloves. Not those cheap yellow ones, though I admit I have about 30 pair, but the strudy blue ones that don’t rip and tear so easily.
I have 15 pair of those and about 100 green scrub pads, which I get Home Depot.
For sponges I buy the 10 pack at Home Depot and have 5 packs of those. Comes in handy when guests are coming and I don’t want them to see an overused sponge.
I just toss the used one and pull out a nice clean one before they come over.
