What to Use on Car Seals – A Practical Guide
Rubber seals in cars prevent moisture, air, and noise from entering through gaps around doors, windows, sunroofs, and boot lids. They create a tight barrier that keeps the vehicle’s interior dry and protected from the elements. Regular maintenance ensures long-term performance and durability.
Why It’s Important to Maintain Rubber Seals
Over time, cold temperatures and UV exposure can cause rubber to lose flexibility, become brittle, and eventually crack or break down. Frequent opening and closing of doors also leads to wear and tear. Proper care keeps rubber seals soft, elastic, and effective, preventing premature damage.
Poorly maintained seals may result in window fogging, air leaks, and moisture inside the vehicle, which promotes mould, bacteria, and rust.
When Rubber Seals Need Replacing
Replacing seals is necessary when:
-
The rubber appears flattened, deformed or hardened
-
There is a noticeable decrease in soundproofing – you hear a metal-on-metal sound when closing doors
-
Water leaks in through the doors
-
You notice wind noise while driving
What to Use to Lubricate Car Seals
The most recommended products are silicone spray and technical petroleum jelly. Both are effective for preserving rubber and extending seal lifespan.
Silicone Spray
Silicone spray is ideal for those looking for an easy, effective solution:
-
Odourless and non-toxic
-
Highly water-resistant and temperature-stable
-
Prevents rubber from freezing in winter
-
Helps protect against corrosion and rust
-
Suitable for use on door seals, boot edges, window guides and even electrical connectors
-
Shields plastic and metal from UV damage
-
Simple to apply and reaches tight spaces
It leaves behind a thin, invisible film that nourishes rubber without leaving stains or residue.
Application:
Spray evenly on clean, dry rubber from 25–30 cm away. Wipe off excess with a clean cloth.
Technical Petroleum Jelly
A thicker alternative, petroleum jelly is ideal for winter protection:
-
Odourless and offers excellent lubrication
-
Prevents rubber from freezing and sticking
-
UV-resistant and protects rubber from cracking and discolouration
-
Can also be used on leather and plastic components
How to Maintain Car Seals – Step by Step
-
Clean the seals – Remove all dust, dirt, and moisture.
-
Apply the product – Use your chosen lubricant evenly across the surface.
-
Wait and wipe – Let the product absorb, then remove excess with a clean cloth.
For best results, repeat after each car wash.
Preventing Frozen Seals in Winter
Frozen seals often make doors difficult to open. Forcing them can damage the rubber or the door itself. Avoid DIY fixes like hot water – these can crack windows or worsen the issue.
Instead, apply silicone spray or petroleum jelly regularly. This prevents seals from sticking, protects against moisture, and keeps them flexible even in sub-zero temperatures.
