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.

Good boat wash. Smells good and cleans well

Works really well on our boat.

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.

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.

Good wash for boat

Works great

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
