Is Vinegar Safe For Fiberglass Boats?

Yes. Vinegar is safe for fiberglass boats, but it only has the potential to remove water spots and tannins from fiberglass. Washing with vinegar will help eliminate light water spots on the surface. Bigger water droplets will not wipe off. In addition, vinegar will not corrode metal on your boat as some cleaners can do.

Vinegar does not remove algae or calcium buildup on fiberglass, so if you see mold or a greenish color discoloring your boat, it may need more than just a vinegar bath to clean it up fully.

Vinegar cannot remove acrylics or gel coats from the boat, so it is more likely a problem with your gel coat if you are seeing this.

To dispose of those pesky water spots, you will need to use a mild detergent and warm water, then scrub with a soft cloth.

If you have dark water spots, invest in some calcium strips from an auto parts store to build up the calcium in the fiberglass and allow it to clean itself.

A vinegar solution will remove the tannins from the fiberglass but does not cause the same reaction on the surface as an alkaline solution. Alkaline solutions can help make your fiberglass look new.

Can You Use A Pressure Washer On Boat Seats?

You can use pressure washers to clean items that get dirty easily. This includes durable items such as boats, yachts, and tiles. These items are often costly and need to look nice and in good condition.

However, the issue with using a pressure washer on boat seats is that pressure washers might damage items.

Most pressure washers can heat quickly and cause the boat seats’ material to warp or melt away from the surface. It’s not something you want to bet with when it comes to your best investment.

Pressure Washer Cleaning Boat Seats

The preferable way to clean your boat seats is to use a steam cleaner. Steam cleaners work by heating water and then putting it through a strong air stream.

The hot steam from the steam cleaner then leaves behind that hard-to-clean dirt stuck on the seats.

The issue with using a steam cleaner on soft furnishings is that it can damage them. However, you can use specific steam cleaners on boat seats.

Can You Power Wash A Fiberglass Boat?

Yes. It may seem like fiberglass boats are too tough for cleaning, but using the right power washers can help make the job much easier.

Please note that there are many types of power washers, and your results will vary according to what type of fiberglass boat you have.

Some power washing machines build up pressure while others use air pressure, so you need to make sure that any cleaner you buy is compatible with whatever model boat you have before buying it.

The key is to find a washer that has a high-water flow rate, is of good quality, and has a strong detergent.

A machine with these features will be powerful enough to remove dirt, grime, oil, and other contaminants from your boat without damaging it.

Another key factor when power washing your boat is to ensure you have the right accessories.

You will need a good high-pressure nozzle and a scrubbing wand with a long handle. High pressure can damage some drain lines, so ensure you use the correct hose attachments, such as gun-type fittings.

You will also need to ensure that you do not use too much water. It’s preferable to apply only enough water to get rid of the dirt and grime, but not so much that your boat becomes soaked.

Ask your dealer whether you will need special chemicals to clean your fiberglass boat.

Some dealers sell power washers that have detergents built into them, but others may recommend that you buy your cleaner. You can make yours or buy it at a nearby marina or a hardware store.

How Do You Remove Algae From Boat Canvas?

There are three ways to remove algae from boat canvas, and there are some pros/cons to each.

You can either use a pressure washer, scrub the algae off with a brush or sponge, or use dish soap to create and dispense suds.

The first method is the most time-intensive way to remove algae from canvas because it requires at least 5 minutes of washing for every square foot of canvas cleaned.

This is often not feasible if you have a big boat using gallons of water per minute.

The second method of scrubbing algae off with a brush or sponge is the most labor-intensive way to clean canvas, but it requires the smallest amount of time per square foot.

It also requires a bit of elbow grease and can frustrate since algae tend to stick to canvas as you scrub.

The last method is the most effective way to remove algae from canvas and takes only about 1 minute per square foot but requires a bucket of suds.

Algae on canvas results from sunlight and water acting together to create a hardy, green layer of filmy matter that protects the underlying layer of fabric from UV radiation, which is the major cause of color fading.

The algae can also move around on the canvas, destroying the colorfastness you paid a lot of money for. If you ever see it growing on your boat canvas.

How Do You Remove Mold And Mildew From A Boat Cover?

Cleaning mold and mildew from a boat cover are easy, but you must take proper steps to ensure that no mold or mildew will return to your boat cover.

Using a soft bristle brush, you will need to gently brush the mold and mildew off the boat cover. Avoid using rough brushes as damaged fibers may weaken the canvas.

Use a mild enzyme cleaner or neutral detergent if you use a rough brush.

Note: This method will not remove the mildew from the fiberglass hull.

You can also spray the mold and mildew with a mild enzyme cleaner.

If you have access to an automatic washing machine, you can wash the cover in an automatic washing machine with a laundry detergent and warm water.

Again, check out your owner’s manual for extra information on washing your cover properly.

Important: If you are washing a canvas cover, use laundry detergent and warm water, not bleach.

If you are washing a synthetic cover, you can use bleach to clean the mildew from the cover. Do not mix bleach with laundry detergent when washing synthetic covers.

After cleaning, hang your boat cover to dry in a shady place.

Note: For a long-lasting clean, use a mild enzyme skin cleaner to remove excess dirt and sweat from the boat cover after use.

This will help repel and prevent mold and mildew from returning to your boat cover.

A Boater’s Guide To Less-Toxic Cleaning- Guide

There are many less-toxic cleaning methods that boaters can use today. Many of them are easy to implement, requiring only a few simple steps and materials.

This guide will gradually help you make your boat more earth-friendly, whether on a sailing vessel or a powerboat.

1. Do not use bleach or any form of brand-name disinfectant, such as Stri-DEX 8. These chemicals are very strong and will damage paint and vinyl on your boat and hands.

2. When cleaning the bilge with bleach (or any disinfectant), rinse the vessel and clean rags well before using it again.

3. Use a good-quality, biodegradable dish soap and warm water to wash dishes on board; the warm water will save energy, too.

Why Does My Boat Have Two Steering Cables?

4. Boats must have clean drinking water and sanitary sewage systems. Filtered or bottled drinking water is best for human consumption.

Use an onboard desalinator to convert seawater into drinking water. UV sterilizers will neutralize microorganisms in the bilge and other boat areas.

5. The best way to dispose of wastewater is by using a macerator pump and a holding tank.

6. Use a marine air purifier that uses ultraviolet light to destroy dust and purify the air.


Vinegar will remove mold, mildew, and algae from the fiberglass hull of fiberglass boats and fiberglass travel trailers. It will also remove mildew from a covered boat if used under the canvas.
