Effortless GRP cleaning
I am very satisfied with the product. Enables effortless cleaning of the entire upper deck. Used it for winter storage. Top. I can only recommend. Removes normal dirt that has accumulated during the season. I now use several Yachtikon products because they just work.

The boat was very clean. The dirt was removed very easily, especially below the waterline. The engine and upper hull were particularly dirty and are now very clean again.

Don't remove everything
For stubborn dirt, I like to mix it with polish and household cleaner; then it works without endless scrubbing.

In my opinion, the best cleaner for heavily soiled GRP surfaces.

for cleaning the hull, every year before the winter storage after disembarking

You can save yourself.
If you apply the stuff pure, as stated, you have to wash it off with plenty of water and a sponge after it has worked so that you can remove it from the hull without leaving any residue. I didn't notice any particular cleaning effect. Normal boat wash does the same.
