The Mercedes-Benz R107 is a timeless classic, admired for its elegance, durability, and engineering excellence. However, to keep your SL-Class roadster or coupe in pristine condition, proper cleaning and care are essential. Exposure to road debris, harsh weather, salt, and pollutants can damage your paint, interior, and underbody if left unchecked.
This guide outlines Mercedes-Benz factory recommendations for keeping your R107 clean and well-maintained, ensuring it remains a head-turning classic for years to come.
Exterior Care: Protecting Your Paint and Body
Your R107’s paint and bodywork are continuously exposed to environmental contaminants like tar, tree sap, road salt, and bird droppings. Regular washing and maintenance will prevent corrosion and fading.
Washing Your R107
Use only mild car wash detergents, such as MB AutoShampoo. Never wash in direct sunlight or use hot water to prevent streaking. Thoroughly rinse your car with a gentle spray before washing. Use a soft sponge or microfiber cloth and rinse frequently to prevent scratches. Rinse with clear water and dry using a chamois or microfiber towel. Pay extra attention to wheel wells, undercarriage, and rocker panels, especially after winter driving.
Do not use harsh chemicals, gasoline, or paint thinners, as they can damage your finish.

Removing Tar Stains

Automatic Car Wash Warning
- If using an automatic car wash, be cautious, especially with an SL soft top. Some older car wash systems can trap moisture in taillight recesses, requiring additional drying.
Rust Prevention & Underbody Protection
Although the R107 was factory-treated with wax-based rustproofing, regular underbody washing and inspections are necessary to prevent corrosion.
Wash the undercarriage frequently, especially after exposure to road salt or coastal environments. Inspect for stone chips and touch them up immediately using an MB Touch-Up Stick to prevent rust. Reapply protective coatings to any damaged underbody areas.
Mercedes-Benz does not recommend aftermarket rustproofing, as it may be incompatible with factory coatings.
Glass & Trim Care: Keep Your Visibility Clear
Clean windows with a streak-free glass cleaner to remove dirt and grease. Use a detergent solution to clean windshield wipers and replace them twice a year (before and after winter). Do not use oil-based cleaners on plastic trim or rubber parts, as they can degrade the material.
Interior Care: Upholstery, Leather, and Dashboard Maintenance
The R107’s interior materials require gentle but effective cleaning to maintain their classic look and feel.
Seat Belts – Wash with mild soap and lukewarm water. Avoid bleach or dyes, which can weaken the fibers. Leather Seats – Wipe with a damp cloth, then treat with MB Leather Cleaner. Avoid excess moisture on perforated leather.
Fabric Upholstery – Prevent stains and discoloration by using proper seat covers or avoiding wet clothing. Dashboard & Instrument Cluster – Use a mild detergent solution and a soft cloth; avoid abrasive cleaners. Steering Wheel & Gear Selector – Clean with MB Leather Cleaner for a fresh look.

Wheel & Tire Maintenance
The R107’s alloy wheels are a key styling element, but they require regular care to prevent brake dust buildup and oxidation.
Use MB AutoShampoo for routine cleaning of alloy wheels. For stubborn grime, use MB Cleaner for Light Alloy Wheels. Clean once a week to prevent long-term buildup.
Engine Cleaning & Corrosion Protection
Keeping your R107’s engine bay clean helps with cooling, longevity, and preventing component wear.
Use MB Anti-Corrosion Wax after every engine cleaning to protect metal surfaces. Lubricate all control linkage bushings before applying protective coatings. Protect V-belts and pulleys from wax application.
