Washing Polyester at 40c instread of 30c

[RPB83]

Hi All,

If I washed the pictured items at 40 degrees rather than the 30 degrees it says in the label would the item loose the glossy shine it has (or have any other issues)?

I have never washed it before.

It is 100% polyester.

Unfortunately my washing machine only has a 40 degree option.

It will be fine, 40 degrees is not hot, it's just above body temperature.
I would turn them inside out because of the logo and do a short/delicate wash.
