I have two older scutts that the inside lids are getting bad enough that small chunks and bits of junk mess up items on top shelf too often

I've already flipped them both so that is no longer option.

I was going to sand them down and I wondered if after I sand them if I should kiln wash the inside face.

Any thoughts?

I just discovered in my googling

Paragon Kiln Coating (brick/lid seal)
A permanent high-temperature liquid refractory coating for all types of firebrick kilns. Apply to the inside of the lid and the top rim of brick walls. Makes a hard surface. Prevents brick from dusting down into the kiln.

Looks like that may be just what I needed

Yes you answered your own question. I never kiln wash the top of the kiln as I would always have flaking onto the pots. When it get to the pint that it is questionable-I replace it. In the long run continued firings with less kiln integrity costs too much in energy consumption, and there is always the risk that I would lose that really fine piece that may have been a show stopper, ha ha !

Since your question was answered I thought I would ask you one. I am getting ready to flip my lid and was wondering if your lid had a silver finish on top, the Skutt tech told me that it would change to off white when it was fired. Is it a silver a paint that burns off and creates a lot of smoke, I have had this kiln for at least 30 years and it was used when I bought it. Any info on this subject would be very helpful. Denice

@ Denice... it sort of looks grayish but it's not a finish really

It smells a bit after flipping and does burn off after one firing and it worked fine for a few years until now.

@Pres... I use our new kiln for the show stoppers currently and the older ones only when needed for time sensitive jobs that need to get done which happens a lot more with the upcoming holidays so I'd like to get at least one of my oldies upgraded.

Since I'm adding a new vent I was taking it apart and thought I may as well fix some bricks lid, elements, thermocouple while I'm at it.

I think I'll look into lid pricing too before I decide fully what path I'm taking.

I didn't know if you have a ceramic supplier near you, some times you can buy a used lid, I started out trying to buy a good used lid, he had just sold one and said it would be a while before he got another one, but he had a floor I could use for a lid. I bought the floor for 35.00 and told me that a good used lid was 75.00, since I'm now flipping my lid I'm replacing my floor with the new ventilation system installation. Thanks for your info on the lid, I think mine must be painted because it's metallic silver, I'll fire it on a nice day with a lot of ventilation. Denice
