GRP is a natural product, so it can be cleaned in the same way as other wooden surfaces. However, some products may contain chemicals that should be treated with caution when cleaning.
The easiest way to clean GRP is by using a soft cloth and warm water. Do not use detergents or abrasives as they will damage the finish on your boat.
If you want to remove stains from GRP, then you can use household cleaners such as bleach and ammonia. These products are generally safe to use on wooden boats, but they should be avoided if you have children or pets in the area. The GRP is a very popular material, but it can be damaged by the sun, rain, and the elements. Therefore, we recommend that you clean your GRP every 3-4 months.
The first step in cleaning GRP is to make sure that the surface is completely dry. If it’s not, you will need to use a solvent based cleaner, such as acetone, to remove any water stains or mildew that has developed on the surface.
Next, you will need to remove any loose dirt or grime using a soft damp cloth. Make sure that you do this gently as you don’t want to scratch the surface of your GRP. Use a soft brush or cloth to clean off any dirt particles on the surface of the GRP. You can also use a wire brush to remove dirt deep down into the gaps between your boat and its support system. Be careful not to scratch or damage the paint underneath as this could lead to rusting over time.
Once you have removed all of the loose dirt and grime from your GRP, you will need to give it a good clean with warm water and some detergent. This should be done in small amounts at a time so that the GRP doesn’t become too saturated.
Once the cleaning process is complete, rinse off all remaining detergent using clean water and then wipe down with a soft dry cloth or sponge to get rid of any excess moisture before drying off with paper towels or a towel.
GRP is a marine grade resin and is extremely durable. As with any composite product, it is important to maintain the integrity of the boat by keeping it clean and free of algae and fungi. There are several ways to achieve this, including:
Regular cleaning with a high pressure hose nozzle and biocide solution. This can be done at the end of each season and will remove any surface mould or algae growth, as well as removing dirt, dust or any other foreign matter that has built up on the surface of the boat over the winter months.
Once this has been completed, if necessary use an ultraviolet light to kill off any remaining mould spores or algae growing on the surface of your boat.
Regularly check for signs of corrosion after cleaning with a high pressure hose nozzle and biocide solution. Corrosion may occur in areas such as underneath railings and around hardware items like anchor windlasses etc., which should be removed before further damage occurs during normal use.
