All my pots are now All-Clad stainless. I do not even bother with preheating. They are much better than teflon!

Get yourself some Bar Keeper's Friend to polish the cooking surface if it starts showing any marks or sticking.

Second the All-Clad. I started with a set, a few pans of which I do not use. Then I added as I needed. I could leave it to my kids if I had any. Stuff will last forever.

I switched to Dearborn Denim after searching for Levi's replacements. I vastly prefer the 100% cotton ones- 100% cotton 13oz denim sourced in Mexico. I have tried some of the stretch denim and it is just not my cup of tea.

I buy Fresh Clean Tees from their website. These are the best fitting t-shirts I have ever found, including many that were more expensive. A 5-pack of white tees is on sale for $80. They seem to last longer than others as well, but I did have one where the bottom seam came out. One out of about twenty.

I also pick up t-shirts at Target called Pair of Thieves. I have a few black ones and they seem good and long lasting. They have more of a soft synthetic feel.

The washing soda is the key ingredient. I had trouble with sheets and started doing all the things they tell you on the internet. As I experimented I was using multiple things, in the end it was detergent and Arm and Hammer Super Washing Soda that worked without other ingredients. The washing soda get rid of sweat stains.

I replaced all my 30 year old Revere Ware with All-Clad. I like them much better.

I have that same model of air purifier in my bedroom. I have a larger unit of the same brand in the main part of my home. I let a roomba type vacuum cleaner run in my bedroom twice a week. I dust weekly. I wash my sheets weekly. I bought new pillows and have covers on them under the pillowcases. This has helped a good bit. Dusting and vacuuming frequently will really help! If your computer is covered with dust by the fan, you are not doing enough, and you should clean that as well. You just have to proactive about your dust!

Pretty sure you can get an upholsterer to replace those. They know how to hide any seams and what foam and batting to use. My cushions are in amazing shape, and I sit or lay on mine all the time. They get abused and still hold their shape after 16 years.

I have a modern style Natuzzi leather sofa with very thick, black leather. It is 16 years old and looks like new. It survives German Shepards, Pit Bulls, and little dogs that like to dig. One little dog tried digging through it. A little black shoe polish later and I cannot tell where the dog did this and that dog passed away over 10 years ago.

You need full grain. You will pay more, but it will last.
