Pillow cover got some discolored spots over night

This is where it was easiest to take a picture but it used to be a greenish yellow and you can see how it's darker in the middle. Anyone got any ideas?

Gunk in dishwasher please help!

The temperature knob doesn't turn anymore. Help?

The one on the left does temperature but it's stuck in position while the one on the right is to turn the shower off and on and works fine. My theory is the hard water in my area has gunked up the tap into a stuck position since we don't change the temperature much. What would be a good way to descale it? I have Oust liquid descaler, Viakal spray, white vinegar, etc. but don't know how to get it to the mechanism.

How do I remove the gunk? I’m going insane.

This has been sitting in my sink for months because I can’t figure out how to get the gunk out of the sides

Removing spot from T-shirt

It might be a goner. This blue spot appeared on the back my cotton T-shirt. No idea what it is. Maybe marker since I work with kids and was in a school that day. Any tips, tricks, or ideas on how to get this out? Or maybe it’s done for? TIA!

Just moved into a new place

Is this something that can be cleaned with something like the pink stuff, or is this damage to the glass? Thanks in advance!

Water stains on metal table

I have this outdoor “metal” table as the manufacturer (PHI) states. It is not aluminum because it rusts, but this is not the problem. The issue is the water stains on the top that I can’t remove. Any advice on how to clean it? PS. It is paint coated. Thank you

Foundation stains on white dress from over two years ago. Still possible to remove?

I wore this dress once, never washed it. Some foundation drops got on it and I think I may have tried removing it with water only and just forgot about it. Is it worth trying to remove? The dress unfortunately has no tags to say what kind of material it is; it feels cottony, but could be a polyster blend. Only has a tag that says "Do not bleach. Steam iron. Dry cleaning only. Do not tumble dry." I saw some posts about dawn dish soap and then baking soda. Worth trying? Or will I damage the dress?

Water stain on table

I suspect that this stain was caused by a cup of hot coffee. It's my wife's table, possibly lacquered teakwood. She asked me to find out how to get rid of it and so I turn to the greatest source of competence on the internets that I know! Any tips greatly welcome l.

Is there a way to remove deodorant stains from clothing?

Probably 90% of the shirts my boyfriend owns are all stained from his deodorant. He gets super sweaty easily so he can’t cut back on the amount of deodorant he uses lol.
