Acer white grubs

Hi, I'm new to the forum but I can't see anything similar to my query.
We have a lovely 10 year old potted acer and this year is the first time it's turned a beautiful crimson, but, it's also covered in white things which at first I thought was deposits from sparrows ???? however more have appeared and I can't find out what they are. They look like grub shells..
Would love to know what they are and if they can be treated
A species of scale insect, pulvinaria (forget which one). I just wash them off because they're rarely in large numbers. Perhaps a mild detergent will clean the leaves and young stems and remove any honeydew they have exuded.
Many thanks H-C I was worried they might be destructive. There are quite a lot of them but the picture doesn't show it.
