Frequently Asked Questions (FAQ)

What is the best aluminum boat cleaner?

Over time, even the best-looking aluminum boats start to look a little dingy with oxidation. It will probably not be a huge surprise to you to know that this is caused by pollutants in the air. When these pollutants mix with water, it can take on a white or dirty appearing color.

If you like to keep your boat looking shiny and new, you will need a boat cleaner like the ones you will discover about in the review below. One of the best you will find is the Natural Base Boat Cleaner. It is a biodegradable cleaner that is salt and ammonia free and doesn’t require rinsing.

How do you remove oxidation from aluminum boat?

A: It depends on how deep the oxidation is. It is possible that in some cases the only way to completely remove it is with sandblasting. This is the action of blasting away layers of metal one at a time until the bare metal is revealed.

Other times a spray on replacemeant, such as Cquartz Finest Auto (p. 70) or CLQ1 (p. 93), may be enough. The key is finding a product that can treat and adhere to the highly porous and chemically reactive nature of aluminum.

I scoured the world looking for the best aluminum boat cleaners for this book, and this list represents the top ones. All of the products below are proven cleaners for aluminum boats.

What is the best aluminum brightener?

Star Brite is a popular and well-known brand of boating supplies and their aluminum tops and boats cleaner is no exception.

How do I remove hard water stains from my aluminum boat?

Scored surface can be effectively repaired by removing hardened deposits of calcium, lime, or iron with a combination of electrolysis and crocus cloth.

In a nutshell, an electrolysis bath uses electrolysis action to dissolve minerals from the surface of an aluminum alloy. The effect can be produced with an ordinary 12-volt battery with a 6-foot 2-conductor extension cord.

The 12-volt battery will be connected up across a network of fine lines of crocus cloth or emery cloth. When attached to the battery, electrolysis action will reduce the mineral deposits.

In essence, electrolysis action is the process of converting an ionic compound into an ion and electrons.

The electrolytic chemical reaction will be facilitated with a piece of aluminum turned into an anode and a chemical called a salt that attracts electrolytes as an electrolyte.
