Homemade Fiberglass Boat Cleaner

There are various boat cleaners manufactured and sold commercially that can be used to get rid of tough stains or to give a glossy showroom shine to fiberglass surfaces. However, you can make your own effective boat cleaner as an alternative to the store-bought versions by using household items and ingredients. These cost-efficient cleaning solutions will not damage the protective gel coating on fiberglass boats and will leave boats sparkling.

Pour one pint of water into a clean bucket.

Use a measuring cup to add one cup of 70 percent isopropyl alcohol to the water.

Add one tablespoon of ammonia.

Mix the items thoroughly with a mixing stick.

Use a funnel to pour the mixture into a plastic spray bottle.

Spray the mixture onto the fiberglass boat and clean the boat with water and a clean rag.

Mix two tablespoons of cornstarch with one gallon of warm water in a bucket.

Add one half cup of ammonia and one half cup of white vinegar to the cornstarch and water.

Mix the ingredients thoroughly until they have dissolved into the water.

Use a funnel to pour the mixture into a plastic spray bottle (without spilling). Apply this mixture to the fiberglass boat surface and wipe off with a clean, damp rag for a showroom shine.

Add one half cup of baking soda to one gallon of warm water in a bucket.

Add one half cup of white vinegar to the mixture, as well as one cup of ammonia.

Use a mixing stick to mix the ingredients thoroughly.

Pour the mixture into a plastic spray bottle. Spray the boat cleaner on various boat surfaces, as well as fiberglass surfaces. Rinse with a clean, damp rag.
