Review on 🧼 303 Tonneau Cover and Convertible Top Cleaner - Vinyl and Fabric Top Cleaner - Powerful Cleaning Action - Eliminates Stubborn Stains - Leaves No Residue - 16 fl. oz. (30571CSR) by Ramesh Eastep

303 is the only product I have used so I have no comparison. I haven't had any water seepage through the canvas so I assume this works. My Miata is garaged or upgraded but I have noticed that the dents on the convertible frame are now getting darker and cannot be removed after using a cleaner. The most frustrating aspect of using a "set" is the heavy leakage from atomizers. no problem when using the cleaner and active car and hood wash, but leakage and overspray on the paintwork and windows, you have to remove it with difficulty, otherwise streaks and stains will appear. I've used newspaper and cloth towels to cover these areas (haven't tried plastic curtains yet), but since the leak from your sprayer is a droplet-sized blob, and you're constantly moving to evenly apply those blobs, throw them outside the Curtains. , can only be discovered after drying. I now put the protectant in a professional ZEP spray bottle that I bought at the hardware store.
