Glad to have you here in the Community, @Glue devil.

Currently, the option to completely delete inventory items still isn't available in QuickBooks. However, you can consider inactivating the items as mentioned by my colleague Jen_D above.

I know you've got a vast amount of undesired items in the inactive folder and want to delete them completely in QuickBooks. But I want to let you know that your voice matters and I'm submitting your feedback directly to our engineers. 

For now, you can visit our blog site so you'll be able to get the latest news about QuickBooks and what our Product Care Team is working on.  

Please feel free to post any other questions you have below. The Community and I are always here to help you out.
