Hey, Rusty!
Is it a standard lamp that you have bought - or a table lamp?
We have wooden bedside lamps with which we have always been very pleased, but our standard lamps are metal (from Ikea!)
Now my cooker.......it is a bit of a downgrade from the previous one. This is of necessity rather than choice, as the dimensions were important, as the oven and grill had to fit into the built-in cavity (and even then some adjustment was needed, as I explained earlier!)
The previous oven was self - cleaning......the new one isn't; and, before, we had a timer on the oven......this again has had to be forfeited.
But this I can live without - the most important issue was to make sure that the appliance could fit into the built-in space under the work top.
To answer your question, I wiped down the internal surfaces with warm soapy water as recommended!
And washed the grill pan etc.
And a plus from the gas fitter....he is considering transferring in due course from being specifically a gas fitter, to becoming a general handyman!
Now, that indeed could be useful!
