Toilet seal lube?

I use silicone.

Years ago a parts guy at Camping World told me regular Vaseline was the best. It has worked well for me on a few occasions.

Vaseline is a petroleum product. NO petroleum product should be used on the seal. Try Plumbers Silicone lube or just plain olive oil.

Go to any regular hardware, Lowes or the such and buy something called Plumbers Grease. It is a little packet and costs less than $10.00 here. Apply it to the toilet seal liberally and it should work fine. We had a seal that didn’t work, so we applied the lube and kept that little bit of water in the bowl that you need to keep the seal moist and it held good all last season, will make this a regular part of each seasons startup.

Be careful when purchasing "Plumbers Grease or Lubricant". Not all of them are silicone based.

I've used silicone grease. No leaky seal since.

Do a search for "Dometic 310 series porcelain toilet seal replacement" and there are several options for replacement seals.

Has anyone tried this

Since it's petroleum free and silicone based I bet it would work fine.
