Can anyone give an example of washing powder with oxygen bleach?

[Ihavethebestdogs]

I feel like I'm being a bit dim but in the user manual for our new washing machine (Bosch), it's saying before first use (with clothing) we should run a drum clean with washing powder containing oxygen bleach. I googled and of course 20 billion products came up...
I saw Daz fits the bill, according to Google, but I reacted to this years ago and don't want to buy some just for cleaning the drum.
I called Bosch, waited an age and then the agent couldn't hear me. I called back and was cut off due to high demand. Then Live Chat but no agents were available!

Can anyone suggest what to buy?

Thanks!

Just run a hot wash with soap, don't over think it!

Just use any washing powder that isn't for colours. Daz is now for whites and colours and doesn't contain bleaches.

@Ihavethebestdogs
Sodium per carbonate is another name for it , if that helps.
Vanish / stain remover products contain it as an "active" ingredient

What detergent do you usually use?
Even non bio powders will usually contain bleaches e.g. fairy does

You're getting caught up on the wrong thing, here. They just want you to run a wash with some strong powder to clean out any factory dust etc. Just run it with some normal powder, you'll be fine. I used Morrisons own brand bio to do mine two months ago because I'm not buying new powder for one wash, and it's running perfectly.

Just use normal washing powder and a scoop of oxy whitening powder (cheap £1 versions work just as well)

Add a scoop of a random preferably cheap oxi action powder
