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.

How to fix electrolysis in aluminium boats

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.
