303 Automotive Tonneau Cover & Convertible Top Cleaner, Blue

It cleaned mould off the seams on convertible roof instantly.

Really like the product it goes on well that gives a durable natural shine that's easy to use and gives a waterproof longevity at good value for money .

Used this on my daughters soft top. Liberally sprayed on, left for 20 minutes, then used a drill brush to agitate. The roof came up better, but still didn't get rid of some stubborn marks which I reagitated over and over. Not as good as I thought it would be, and will probably try Fairly Liquid next time.

Excellent product , easy to use and just follow the instructions . It brought back a tan hood from very discoloured to as new condition. Very pleased and would recommend highly.

Works well on my convertible hood. You don't need to use much. Just wet the hood with some water then put about three squirts of this across the roof, use a wet brush or something to work into a foam across the roof before rinsing off. Shifts the bird droppings and any green mould.

Really easy to use and brought my roof up a treat!

Made sure you get any green off first

Excellent product. Glad that I can purchase it in the UK.

Stuff works great. Used it on my convertible top and it got very clean. Very bright looking clean.

Works great, cleans the top, and apparently adds some UV protection

303 is a solid performer. I use it on the dash board and other car parts. I also spray and wipe it on the sky light, vents, and vent covers on my RV. It prevents aging and yellowing on the RV parts, which are exposed to constant sunlight. Good product. Toss your Armor All.

I like this product, but because I retired from Napa my cost thru them was much less.

I read a lot of reviews about the 303 products s ok I thought I would give them a shot. I followed the instructions, sprayed the roof, let it sit for a while then agitated it with a brush, rinsed the roof off and it was spotless! Very easy to use and did a great job!
