I'd take a dry brush to it, then put a tarp around the perimiter, get a bucket of soapy water and sponge it down. You might need to scrub it a bit or do a couple of passes. As long as you don't get the sponge dripping wet, the tarp should soak up any drips. And paint is another option but probably more work than you need at the moment.

I will try that. Thanks!

A hand held steam cleaner would probably work.

Never thought of that…thanks!

Simple Green diluted down, spray and wipe a sponge. Labor intensive but works well and won’t damage your finishes.

TSP mixed with water works well on painted surfaces. Use a microfibre cloth, then rinse well. Plastic or heavy towel in carpet to catch any drips. I used TSP recently before painting trim and doors, and I almost felt like I didn’t need to paint after. You can get powdered TSP in a hardware store. It is usually with the paint.

I have heard of TSP just never have used it yet
