303 Marine Clear Vinyl Protective Cleaner – 32oz

Clear vinyl boat windows turn yellow and crack from sun exposure, and the wrong cleaner speeds that up. 303 Clear Vinyl Protective Cleaner is made for this exact job: it cleans and protects vinyl, clear vinyl, Strataglass and Eisenglass windows in one step.

• Cleans and protects against yellowing and cracking.
• Safe on Strataglass and Eisenglass.
• Leaves a streak-free finish with no residue.
• UV protection built in.
• 32 oz. Made in the USA.

Use it on the soft windows of a bimini, dodger or full enclosure. Clear vinyl scratches easily, so wipe with a clean, soft microfiber cloth and rinse off grit first instead of dry-wiping. We stock Presta and Collinite microfiber in our Cleaning & Detailing section.

This is a boat product. If you’re looking after a motorcycle, for vinyl seats and plastic trim reach for 303 Aerospace Protectant instead. And most motorcycle windshields are hard plastic, not clear vinyl, so check what yours is made of before you use this on it.

Storing the boat gear and the bike together over winter? Our Vehicle Storage Accessories section has moisture absorbers, mildew remover and fabric protectant for both.
