303 Products 30571CSR Tonneau Cover and Convertible Top Cleaner - Vinyl and Fabric Top Cleaner - Ultimate Cleaning Power - Helps Remove Tough Stains - Rinses Residue Free - 16 fl. oz. Packaging May Vary

Excellent product. Removed stains from sap from my vinyl convertible top that I thought would be impossible to remove.

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

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

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.

Used it with a 303 Brush. Sprayed it on, brushed it, it foamed, rinsed it off. Top is looking good and I feel better using a product made for and safe for convertible tops.

I got some bird dung on my Mercedes convertible, and used water and a paper towel to try to remove it. However, this resulted in a light-yellow stain that I couldn't seem to get out. So I did some research and found the 303 brand. Lots of good reviews, but in addition to that, they produce their own special brush for convertible tops so that you don't damage the top with an abrasive brush. I received the cleaner and the brush, followed the instructions on the bottle, and it did a great job. Took away the stain completely. The brush was soft, but was exactly what was needed to distribute the solution. It's good to know that there are products out there such as 303 that take everything into consideration, so that you not only clean the stains on convertible tops, but do this without damaging the expensive top.

This returned a 20 year old jeep soft top, stored in a barn, streaked and stained, to looking nearly new. First pass 1) I rinsed it (you should vacuum it first), 2) washed it using car-wash detergent and a super soft car wash brush, and 3) then used 303 on it without letting it soak in and without using the recommended soft bristled nylon brush (I used the super soft carwash brush). This process got the top to 80% of the final clean but was still streaky and had two bird poop spots that remained somewhat visible. I redid the bird poop spots, this time letting the 303 soak in for 5 min (not the recommended 10-20 min because it appeared to be drying) and used a soft, but stiffer nylon brush. Those two spots came out so well I redid the entire top one last time using the 5 min soak and stiffer brush process. I couldn't be happier with the outcome.

I had doubts that this would even work in my top. I followed the directions and like magic, I have a brand new top! This is an amazing product!! I have a khaki top, and it was covered with black streaks !! Amazing product! 10/10!!

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!

It cleaned mould off the seams on convertible roof instantly.

I used this product and 303 Tonneau Protectant to clean & water-proof my summer car's convertible top. Following the provided directions, I generously cleaned & then applied the water-proofing to my canvas top. That was two years ago (though I know I should do this once/year). Last week I had to take a 600 km highway trip, where I drove through rain storms plus it rained on the parked car for much of the night. The next morning to my surprise & delight I saw the water on my top was still beading and rolling off with no indication of any soak through. 303 products are great product which do an awesome job cleaning & protecting convertible car tops, tents and probably most any porous material you don't want water to penetrate. Based on my first application, the bottle appears to hold enough liquid for two water-proofing applications. I'll definitely purchase more 303 Tonneau product to have on hand for all my water-proofing needs.

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 .

Did the job very good
