Cleans Without Stripping Wax
Meguiar’s states that Shampoo Plus removes dirt and grime without stripping existing wax protection. That makes it suitable for regular maintenance washes on protected vehicles. meguiars.com
It can be used on properly maintained:
- Clear-coated paint
- Single-stage automotive paint
- Waxed vehicles
- Sealed paint
- Painted body panels
- Exterior glass
- Compatible chrome and trim
Always test specialty finishes, vinyl wraps, matte paint and paint-protection film according to their manufacturers’ care instructions.
Gloss-Enhancing Conditioning Agents
D111 does more than remove surface dirt. Its conditioning agents are designed to deepen gloss and leave the paint feeling smoother after rinsing.
This makes it a good maintenance shampoo for:
- Dark-colored vehicles
- Show cars
- Dealer inventory
- Daily drivers
- Customer vehicles
- Fleet maintenance
- Recently waxed paint
It is not a polish and will not remove oxidation, scratches or bonded contamination. If the paint still feels rough after washing, our guide explaining why washing is not enough covers the next decontamination step.
Water-Sheeting Rinse
The formula encourages water to sheet away from the surface during rinsing. This reduces the amount of standing water left for the drying towel and may help limit spotting when the vehicle is dried promptly.
Water sheeting does not eliminate the need to dry the vehicle. Hard-water minerals remain perfectly willing to decorate clean paint if allowed to evaporate.
Body-Shop-Safe Formula
Meguiar’s identifies Shampoo Plus as body-shop safe. This makes it suitable for professional environments where silicone-heavy products or wax-containing wash formulas may be undesirable.
Follow the refinisher’s curing and aftercare instructions before washing freshly painted panels. “Body-shop safe” does not mean fresh paint is ready for aggressive washing immediately after leaving the booth.
How to Use Meguiar’s D111 Shampoo Plus
- Park the vehicle in a shaded area.
- Allow hot paint and wheels to cool.
- Rinse away loose dirt.
- Mix one ounce of D111 per gallon of water.
- Use a clean microfiber wash mitt.
- Wash from the roof downward.
- Clean heavily contaminated lower panels last.
- Rinse the mitt frequently in a separate rinse bucket.
- Do not allow soap to dry on the surface.
- Rinse thoroughly and dry with a clean microfiber towel.
For heavily soiled vehicles, use a pre-rinse or pressure washer before contact washing. Adding excessive shampoo does not replace removing abrasive dirt first.
Bucket Washing vs. Foam Cannons
D111 is officially specified at 128:1 for washing and professional dispensing systems. Foam-cannon concentration varies by equipment, water pressure and orifice size.
When using it with a foam cannon:
- Begin with the equipment manufacturer’s recommended ratio.
- Adjust only enough to achieve useful coverage.
- Do not assume thicker foam cleans better.
- Complete the wash with safe contact-washing methods when necessary.
- Rinse the cannon after use.
