My favorite combo for canvas tops are:

303 Fabric Cleaner - Clean up existing stains and prep the surface for the protectant. This product has many benefits. 1) It's a concentrated formula, so you can dillute it to the ratio that is needed to remove the stain. 2) It's a amazing all purpose cleaner for leather, vinyl, rubber, carpets, engine degreaser, and plastic. We usually use a 6:1 (water:303) mixture for most instances so that will make 6 x 32oz bottles = 192oz of cleaning solution.

303 High Tech Fabric Guard - This will help bead water and prevent stains from penetrating into the convertible top. Also works well on carpets and floor mats to prevent future staining.

Hope this helps, if you have any other questions, please do not hesitate to ask.

Sincerely,
