## Overview

3-IN-ONE RVcare Rubber Seal Conditioner is a premium 11 oz spray designed to protect and extend the life of rubber seals on RVs, boats, cars, and more. Featuring UV inhibitors and a water-resistant formula, it prevents cracking, fading, and friction damage. The innovative Smart Straw allows precise application with two spray options, ensuring easy maintenance of slide-outs, windows, doors, and compartments. Highly rated and trusted by thousands, it’s the essential solution for professional-grade seal care.

## Description

Poorly maintained rubber slide-out seals or gaskets can cause deterioration and cracking that allows water, dirt, wind, and even rodents to enter RVs. Contains UV inhibitors which help prevent cracking and fading. Long lasting water resistant formula reduces friction and wear. Extends the life of rubber slid-out and other seals when used regularly. Also works to protect other RV rubber seals including those on windows, doors, compartments and hatches. Great for conditioning rubber seals on RVs, boats, cars, and other vehicles. Safe to use on rubber, metal, vinyl and plastic.

Review: Great on house windows too. - I don’t have a RV, I use this on my house windows. It works great. Squeaky hard to open and close windows fixed. Spray on wipe clean and spray again. Do not wipe clean the second time.
Review: Lubes great, straw keeps your windows clean - All my RV windows were hard to open. Used this lube on the tracks and now the full-size horizontal window opens smoothly with about a quarter of the effort. The straw nozzle made it easy to reach past the shades to lube the upper track with very little overspray. (I made the mistake of lubing the screen channel as well, and now the screen follows the window every time I open it -- oops!) Our vertical windows saw more limited improvement, but the design of their locks and grips is super poor to start with. This product is a keeper.

### ⭐⭐⭐⭐⭐ RV window slide oil to help windows slide and not collect dust.
*by K***E on January 10, 2026*

I bought this to use on my recreational vehicle. First time to use a dry lube. Works great and doesn't collect the dust and dirt like oil lube does.
