Meguiar's M43 Marine/RV Boat Wash, pH-Balanced Boat/RV Wash for Protecting Fiberglass and Gel Coat, Streak-Free Shine that Keeps Surfaces Clean and Protected, 64 Oz

This was excellent wash I used it on my RV which as a fiberglass shell and it removed the dirt and black streaks better than any of the other car washes I've used, even worked better than the wash "Made Exclusively" for removing those streaks by another manufacturer.

Wow. It actually got all the the winters nasty gunk off the seats. We were impressed

Love, Love, Love Meguire products. This is great boat wash for our 44ft Carver MY. Suds up well, don't need much, so will last. Easy to use. Smells great, leaves boat looking new and shiny. Highly recommend.

Price is very fair vs other boat soap and thats why I love it. Also, it smells amazing off the bat. Is it the best boat soap? No, not even close. But it does well with making the boat shine and cutting through light stains (tougher stains and grime need some elbow grease). If not rinsed quickly, it will leave spots/streaks on windshields and cowlings. My one issue with this soap is that the suds don't stay well. It has great foaming action initially, but after a 15-20 min, they start to fade, and fade fast. Then you are left with a milky water will little foam. It still cleans, but not as well. To me, there is nothing like that first mitt dunk and slap onto the gelcoat with suds spraying everywhere, that's what I would like after 1/2 hour but I may be asking to much. I clean my boat harder and better then everyone at the dock and I get many compliments and I use this soap so ... make what you want from it.

Good boat wash. Smells good and cleans well

Good wash for boat

I bought this because my boat was looking like it had been marinating in swamp juice and bad decisions. I’m talking full “found at the bottom of a lake in a horror movie” vibes. One wash with M43 and suddenly my boat looked like it pays taxes and has a LinkedIn. First of all, this stuff foams up like it’s training for a bubble bath commercial. I hit the hull with it and the grime started sliding off like it didn’t want the smoke. Bird poop? Gone. Mystery lake slime? Evicted. That weird brown streak that’s been judging me for three summers? Sent to another dimension. It smells way better than it has any right to. I was fully prepared for “industrial chemical that dissolves fingerprints,” but instead it smells like responsibility and a fresh start. What I love most is that it actually cleans without stripping everything like you just power washed it with regret. My gel coat still beads water like it’s flexing. No chalky nonsense, no sad faded look. Just clean, shiny, and mildly threatening to the next seagull that tries something. Used it on my buddy’s RV too because he said, “It’s fine.” It was not fine. It looked like it had driven through three states of pollen and one biblical plague. M43 handled it like a champ. Now he thinks I detail professionally. I do not. I just read the back of a bottle and commit. Is it dramatic to say this soap restored my relationship with my boat? Maybe. But I’ve spent more on worse decisions that didn’t make my hull this glossy. 10 out of 10. If this soap had a fan club, I’d be treasurer.

Used recently to wash my fiberglass casita. I used a soft brush and this solution kept its suds throughout the wash. I'm am very happy with how clean my trailer became with no too much effor

The boats wash is great but the service was even better! Had a minor hiccup however it was all sorted very quickly 10/10 service keep up the great service

Alors, moi je n'y croyais pas. La notice indique un pourcentage (qu'on traduit en litre car c'est indiqué en galon) extrêmement faible. Mais si, c'est bien de l'ultra concentré. Il suffit d'en diluer très peu pour être efficace. Je recommande!

Does what it says and does it well
