YBP-0305 Serious Multipurpose Cleaner for Black Streaks on Fiberglass, Vinyl, Non-Skid Decks & Graphics, Boat and RV Surface Cleaner - 32 oz.

If you get spider droppings on your vinyl boat seats, this is the only product that takes off the stain. I have been using for years and will not purchase anything else.

One of the best all around marine cleaners I have used. The best part about it is you only need one bottle on the boat. You can use it on paint ad gel coated surfaces, glass, electronics, wood, Formica, vinyl, metal. One cleaner for all surfaces! Even in the engine room. We had an exhaust leak and when we got back in and to cleaning up the engine room everyone was telling us how hard it was going to be to get the diesel soot off of everything. I mixed up an extra strong batch of SMC and sprayed down the engine room, let it sit a couple of minutes and for the most part just rinsed everything off. A few spots need a second application and some light scrubbing with a brush but it made extremely quick work of cleaning up a very dirty mess.

Great product. As many are aware sun tan lotion is a nightmare to remove. With this cleaner and some elbow grease (deep scrubbing) it got it out! Use as directed, but let it soak in a little longer and scrub out, i did a few times to get it out completely

While it cleans well, I found that it's not "spray on / hose off" as described on the bottle. I tried a garden sprayer with 1 to 4 ratio as directed. Sprayed the some of the boat bottom, waited a minute the sprayed off with a hose. Nada. Still stained and dirty (but just a film. Not like it was years of accumulation) so spraying on / hosing off won't get the job done. When I switched to a bucket and bristle broom grime started coming off fast. So, took a star off because the directions are incorrect. Still, I'll be purchasing more when I run out so I DO RECOMMEND.

I had suntan lotion on my boat seats and nothing was able to take it off. This was the first product that took it off without harming the seats.

By far the best all around cleaning/detail product for ALL marine surface (final, glass, fiberglass, plastic, brushed aluminum, etc.) I have ever used, and I have tried most and consider myself a detail freak.

Didn’t work at all

This cleaner works as advertised. It is great. I have a 10 meter 1988 Trojan International Express Cruiser and this is the only cleaner that I use on the exterior of the boat. Be sure to follow the mixing instructions of 1 part cleaner to 4 parts water and follow the instructions on how to use it.. It is a strong concentrate. Much cheaper to buy the concentrate and mix it yourself than to buy the smaller spray bottles of premixed cleaner.
