Removing Pitting from Aluminum Boats

Alu­minum boats are known for their dura­bil­i­ty and longevi­ty, but they can be prone to cor­ro­sion. Pit­ting is a com­mon prob­lem that can occur on alu­minum boats, and it can be very unsight­ly. For­tu­nate­ly, there are a few ways to remove pit­ting from alu­minum boats and restore them to their orig­i­nal con­di­tion.

How to Remove Pitting from Aluminum Boats

Remov­ing pit­ting from alu­minum boats can be done in a few steps. Scrub the affect­ed area with a soft brush and a mix­ture of bak­ing soda and water. Be sure to use a scrub brush that won’t scratch the alu­minum. 

1. Iden­ti­fy the Pit­ting: First things first, make sure what you’re deal­ing with is actu­al­ly pit­ting. These are usu­al­ly small, shal­low holes in the sur­face of the alu­minum. It often looks a bit like the sur­face of the moon if you squint a bit.

2. Clean the Sur­face: Get your boat nice and clean. Use a mild deter­gent and water to remove dirt and grime. Rine­ly thor­ough­ly and let it dry.

3. Pre­pare a Clean­ing Solu­tion: Now, onto the fun part. Mix a solu­tion of equal parts water and white vine­gar. This acidic solu­tion will help to clean and bright­en the alu­minum.

4. Apply the Solu­tion: Soak a cloth in the vine­gar solu­tion and apply it to the pit­ted areas. Let it sit for about 15–30 min­utes. If it’s a hot day, you might need to reap­ply the solu­tion to pre­vent it from dry­ing out.

5. Scrub the Sur­face: After the vine­gar has had time to work its mag­ic, use a soft brush or sponge to scrub the pit­ted areas. Be gen­tle – you don’t want to scratch the alu­minum.

6. Rinse and Dry: Rinse off the vine­gar solu­tion with plen­ty of water. Then, dry the sur­face to pre­vent any water spots from form­ing.

7. Pol­ish the Alu­minum: Using a met­al pol­ish designed for alu­minum, apply it accord­ing to the man­u­fac­tur­er’s instruc­tions. This will help to smooth out any remain­ing pits and bring back the shine.

8. Seal and Pro­tect: As a final step, con­sid­er using an alu­minum seal­er or wax. This will help to pro­tect the sur­face and keep that new­ly pol­ished shine look­ing fresh for longer.

Make sure to thor­ough­ly clean the area after pol­ish­ing and wax it to pro­tect the alu­minum and keep it look­ing shiny. You may want to con­sid­er apply­ing a clear coat to the area to make sure it is ful­ly sealed and pro­tect­ed from fur­ther dam­age. Fol­low the instruc­tions on the prod­uct to make sure it is applied cor­rect­ly. With these steps, you can restore your alu­minum boat and keep it look­ing great for years to come.

Pit­ting is a type of cor­ro­sion that can occur on met­al sur­faces, includ­ing alu­minum boats. Pit­ting is caused by expo­sure to salt water and oth­er cor­ro­sive mate­ri­als, and it can cause the sur­face of the boat to become rough and irreg­u­lar. Pit­ting can also reduce the lifes­pan of an alu­minum boat and make it more sus­cep­ti­ble to fur­ther dam­age.

Preventing Pitting on Aluminum Boats

Pre­vent­ing pit­ting on alu­minum boats requires reg­u­lar care and main­te­nance. The most impor­tant step in pre­vent­ing pit­ting is keep­ing the boat clean. Boat own­ers should wash the boat with a mild soap and water, then rinse it thor­ough­ly. It’s also impor­tant to inspect the boat often for signs of cor­ro­sion, and to address any issues that are found prompt­ly. They might use a pro­tec­tive coat­ing on the boat, such as a wax or pol­ish, to help pro­tect it from the ele­ments. They have to  make sure to dry the boat com­plete­ly after each use, and to store the boat in a cov­ered area when it’s not in use. Tak­ing these steps can help pre­vent pit­ting on alu­minum boats.

Cleaning

Clean­ing the boat reg­u­lar­ly is one of the best ways to pre­vent pit­ting. It is impor­tant to remove any dirt, debris, or salt water from the boat, as these can all con­tribute to cor­ro­sion. It is also impor­tant to use a mild deter­gent and soft cloth when clean­ing the boat.

Waxing

Wax­ing the boat can help to pro­tect it from cor­ro­sion. Wax cre­ates a bar­ri­er on the boat’s sur­face that helps to pre­vent salt water and oth­er cor­ro­sive mate­ri­als from stick­ing to the boat. It is impor­tant to use a wax specif­i­cal­ly designed for alu­minum boats.

Coating

Apply­ing a pro­tec­tive coat­ing to the boat can also help to pre­vent pit­ting. There are many types of coat­ings avail­able for alu­minum boats, and it is impor­tant to choose one that is specif­i­cal­ly designed for alu­minum. Apply­ing a coat­ing can also help to increase the lifes­pan of the boat and pro­tect it from fur­ther dam­age.

Storage

Stor­ing the boat in a dry and shel­tered place can help to pre­vent pit­ting. It is impor­tant to avoid stor­ing the boat in areas that are exposed to salt water or oth­er cor­ro­sive mate­ri­als, as these can cause cor­ro­sion. It is also impor­tant to cov­er the boat when it is not in use to pro­tect it from the ele­ments.

How to fix electrolysis in aluminium boats

Elec­trol­y­sis in alu­minum boats is caused by a chem­i­cal reac­tion between water and the met­al, result­ing in cor­ro­sion. To fix elec­trol­y­sis in alu­minum boats, you will need to address the source of the cor­ro­sion.

1. Inspect the boat for signs of cor­ro­sion, and if found, repair the affect­ed areas. This may involve sand­ing and paint­ing, or replac­ing cor­rod­ed parts.
2. Increase the elec­tri­cal ground­ing of the boat by con­nect­ing the boat’s met­al com­po­nents to the neg­a­tive ter­mi­nal of the bat­tery. If a ded­i­cat­ed ground­ing sys­tem is not avail­able, use ground­ing plates or anodes.
3. Make sure the anodes are made of a more reac­tive met­al than the boat, such as zinc or mag­ne­sium. Replace the anodes reg­u­lar­ly to ensure they are work­ing cor­rect­ly.
4. Install gal­van­ic iso­la­tors to reduce the cur­rent between the water and the boat.
5. Install a cathod­ic pro­tec­tion sys­tem to reduce the cor­ro­sion of the boat’s met­al com­po­nents. This sys­tem will attach a sac­ri­fi­cial anode to the boat, which will cor­rode in place of the boat’s met­al com­po­nents.

Address­ing the source of the elec­trol­y­sis and prop­er­ly installing pro­tec­tion sys­tems can help to reduce and pre­vent fur­ther cor­ro­sion in alu­minum boats.

How to remove pitting from anodized aluminum

To remove pit­ting from anodized alu­minum, you will need to sand the affect­ed area using a fine grit sand­pa­per. Start by sand­ing with a coarse grit, then move to a fin­er grit as the pit­ting begins to lessen. Once you’ve fin­ished sand­ing, use a soft cloth or brush to remove any dust or residue and rinse the area with warm water. Apply a met­al pol­ish to the area and buff it out, restor­ing the shine of the anodized alu­minum.

If the pit­ting is deep and the sand­ing process is not suf­fi­cient to remove it, you may need to use a spe­cial­ized chem­i­cal etch­ing solu­tion to fur­ther remove the pit­ting. Fol­low the instruc­tions pro­vid­ed by the man­u­fac­tur­er care­ful­ly, as etch­ing solu­tions can be dan­ger­ous. After the etch­ing process is com­plete, use the same sand­ing and pol­ish­ing tech­niques as before to fin­ish the job.
