Laundry: I despise the use of bleach, in general, mostly because 99% of my wardrobe is black, and I don't want anything with bleach anywhere near me, but...I do, occasionally, use it in the laundry to brighten up the whites. 1/2c should work, no more than a whole cup in a laundry load, with soap, on hot, will totally take care of your towels and sheets.
Work and nice clothes are inspected, pre-treated, and then washed on Cold and hung dry.Warm, dried on low, and folded.
Unless you're wearing some goofy designer undies and/or socks, that shit gets washed on Hot and dried on whatever the label says. Same thing for sheets and towels.
I use liquid fabric softener, because the sheet will coat your dryer, and not everything needs fabric softener. And, by the way, never put fabric softener in towels of any kind.
Wooden toilet seats: what kinda crud problem are you having? That sounds disgusting...!
