Any question answered...

Rub in some lemon juice, breadcrumbs and salt, leave to soak in warm water for 60 minutes. That should give you time to pop out to Primark to buy a new t-shirt. Throw away the old one on your return.

What’s the best way to remove rust stains from a white T-shirt?

Traditionally, oxalic acid. In modern times now that clothes are so cheap, I think @WillMelling is on the right track unless it's an unusually valuable t-shirt

Buy some decent azo dye that matches.

Toothpaste.

Bit of water to work it in.

Don't try to rub it, it'll mess up the cotton.

Rinse and repeat.

Boot polish. Rub it in thoroughly.

I think the Cloudflare protection that bossman uses as the 'front door' to the site blocks known bad IPs. Sadly, it's not smart enough to distinguish individual bad actors from large public networks used by bad actors. Thus, all access from some public WiFi services is blocked.

You would be suprised how well sunlight will bleach stains out of white cloth too

Is everyone just ignoring Will’s stated preference for not tagging them?
Why?

I see! Thanks for that.

I want to rent a villa, golf me, if I use a credit card to pay: what am I protected against ?

The supplier going bust or the villa not being as described - assuming you spend between £100 and £30000 on the card. You aren't covered under section 75 if you go through an intermediary though, eg if you book your villa through booking.com and not direct with the villa owner.

But you can't dissociate ferric oxide with UV until you get to a power level where the shirt would be vapourised before the stain was touched 🙂

UV is good (or bad, if you don't want things to fade) for breaking up colourful organics into colourless fragments, but useless against most inorganic salts

I have booked direct with owners many times. The only time there was a minor issue was when they sold the villa (we had booked about 9 months prior) they refunded all of the money paid and apologised for the inconvenience.
All of mine were either word of mouth or I had booked previously through Airbnb etc and subsequently went direct.

Is there an aquarium/fishkeeping thread on here somwhere?

..yes, it's here 👍

Umami strain removal?

In catching up on past achievements, I remembered to respond to you again.
Thanks, it worked a treat.
Ended up having to make a paste off the pellets because the solution wasn't strong enough, apply liberally with brush and have that fizz the anodising away over a couple of hours. Satisfying.

The crankarms are now much more shiny due to polishing effect of toe straps.
But yeah, thanks again for the tips!

It used to look like this:

This would perfectly! Thank you. I had tried some stain remover before the lemon juice/sea salt and it didn’t do much.

Enduro or NTN are what I am about to replace mine with

London-based place to re anodize chainrings?

I've broken a key off in a lock. What are my options?

This fucking day!

What type of lock? If it’s like a Yale lock on a door, you can try press in a flat head screwdriver to turn and unlock it. I managed to do this once, but replaced the lock as I couldn’t be bothered trying to get the broken key part out.

Edit - ah I couldn’t see that photo a minute ago. The right sized flat head screwdriver might work here
