Boat Juice 2in1 Exterior Boat Cleaner & Protectant Spray combines cleaning and protection in a single step, making it a convenient choice for boat owners. It effectively removes mineral deposits and hard water spots, which are common challenges for aluminum boat surfaces. The inclusion of a SiO2 ceramic sealant helps leave your boat with a glossy, spot-free finish and some protection against future dirt and water marks.

The cleaner is easy to use with a spray-on, wipe-off application that works on both wet or dry boats, and it’s safe to use on various parts including gelcoat, chrome, glass, vinyl, and plastics. This versatility also extends to trailers, which is helpful if you want to keep all your boat equipment looking good. Another standout feature is its pleasant tropical scent, making the cleaning process more enjoyable compared to typical strong-smelling marine cleaners.

This product is effective and user-friendly, suited as a maintenance or light cleaning solution rather than a heavy-duty cleaner for serious grime beyond water spots and mineral deposits. Boat Juice offers a practical solution for those seeking an easy, pleasant-to-use cleaner that also protects, ideal for regular upkeep of aluminum boats and related surfaces.

This product provides long-lasting polymer protection, which includes UV protection to guard against sun damage, a crucial feature for boats exposed to harsh marine environments.

The wax leaves a dazzling shine, contributing to a well-maintained and visually appealing vessel. Applying the wax is straightforward: just dispense a small amount onto an applicator, spread it evenly, and remove it with a towel. This ease of use is a significant advantage for boat owners who prefer a hassle-free maintenance routine. Additionally, the product's versatility allows for both hand application and use with a dual-action polisher, catering to different user preferences.

However, it's worth noting that this product is specifically formulated for fiberglass and gel coat surfaces, so it may not be suitable for all boat materials, particularly aluminum.
