The Irish company, Yellow Dolphin, makes cleaning agents for yachts. Grunt! is a remedy that promises to remove the stubborn yellow deposits on gelcoat or painted surfaces without scrubbing. Simply apply, let it soak for 30-60 minutes and rinse. There are more products that can make this happen, only Grunt is based on phosphoric acid instead of oxalic acid that cleans surfaces. For our test on a winter day, we try a part of a somewhat yellowed Gibsea 76 sailing yacht outside. After we have shaken the bottle well, we apply the jelly-like substance with a brush. Because it is only 8 degrees outside and therefore colder than the recommended minimum 18 ° C for a 30-minute treatment, it is recommended to extend the exposure time and so we do.

There are more products that can make this happen, only Grunt is based on phosphoric acid instead of oxalic acid that cleans surfaces. For our test on a winter day, we try a part of a somewhat yellowed Gibsea 76 sailing yacht outside. After we have shaken the bottle well, we apply the jelly-like substance with a brush. Because it is only 8 degrees outside and therefore colder than the recommended minimum 18 ° C for a 30- minute treatment, it is recommended to extend the exposure time and so we do. We leave it on our test zone for an hour. The packaging states that the product is non-toxic and completely biodegradable. What exactly is in it is not mentioned but on the site it says that it complies with the strict MARPOL (Marine Pollution) rules. After an hour we rinse the hull with water with a good result. Scrubbing is not necessary and the yellow area is really gone. Because we have only covered and treated part of the hull, the difference with the rest of the hull is clearly visible. The diesel stain around the water outlet of the engine is not completely gone. These stubborn stains remain visible even after a second treatment. The product thus appears to concentrate completely on the yellow areas, a problem that many yacht owners struggle with, so that is good news. Our 100ml test bottle was sufficient for about 3 m2. The product is available per 500ml or per liter bottle. Conclusion: Grunt! is a very good way to remove yellow stains from gelcoat and painted surfaces. Only brushing on, letting it work and and rinsing with water is indeed sufficient. So the product does what it promises. Moreover, it is completely biodegradable and has an excellent price-quality ratio. Price:. € 23.20 (1 Liter) @credits: text Erik van den Berg Minitest: Grunt!
