Toilet Seal Question

One of the staff at my dealer told me that when I'm not going to be using my trailer for awhile that the best thing for the rubber seal on my toilet is to put a few ounces of brake fluid in the bowl while the trailer sets. Do any of you have a thoughts about that recommendation?

Haven't heard that one. I keep either water or antifreeze on the seal.

That's a good way to contaminate the waist water and I wouldn't do it. I just make sure that there's always about an inch or less of just good old water in it.

Never heard of using brake fluid ...., but a cup of RV antifreeze in the toilet and some in the tank has always worked for me in keeping the dump valves and seals functional.

There are some RV tank conditioner products on the market (Thetford, etc.) that contain lubricants for treating plumbing system valves and seals.

I would have to think the brake fluid would eat the rubber seal away,also any brake fluid that gets mixed into the tank cant be good either.I would rather use like a light cooking oil or something that isnt gonna be corrosive

Ok it's early in the morning and I'm sleep deprived but, when I saw this thread, my first thoughts were, why would anyone keep a seal in a toilet—wouldn't the seal be a bit crowded—and why would anyone keep a seal in water and antifreeze? The SPCA would have a field day with that.

My new rig has a sample packet of that Thetford lube seal with my packet. I used it several times and it seemed to help. Plumbers silicone would help also. I would not use brake fluid or any petroleum base product on the rubber.

Just keeping it clean and wet will prevent many problems.

I keep a can of Pledge furniture polish with moisturizer in the bathroom cabinet. After every trip, I give the seal a quick spray while closed. Keeps it nice and pliable.
