Alright

After Boracol was practically discontinued, I looked for an alternative.

My primary goal was to remove the winter stains, black spots, and green growth.

I used a neutral cleaner from Frosch for pre-cleaning.

Applying the NANOPROTECT Wood Degreyer is a bit time-consuming. I rinsed it off with a pressure washer, but that's not exactly readily available in a harbor.

The result, however, was worth the effort. The product not only removed the black mold stains and the graying, but also noticeably improved the surface texture of the wood.

OK.

Used for cleaning teak, but it should be specified that it is very dangerous, and to use adequate protections
GLOVES, BOOTS AND ADEQUATE EYE PROTECTION.

It is not a 'mild' or delicate product and is very acidic.

I got a drop in my hand that I rubbed with the other hand, in 5 minutes I started to feel tingling on my hands and the skin had become completely white, a bad burn.
Also if you walk barefoot while cleaning teak, the product is also released during rinsing (in addition to the vapors during application).
Basically it is a nitric acid solution so be careful that it is not a 'delicate' stain remover or cleaner but ACID.

Now I am using burn creams on my hands and feet.

Would I buy it again? YES, BUT ONLY TO HAVE MY MOTHER-IN-LAW APPLY IT.
