Heavy duty boat bottom cleaner



Redihans WSI Boat Bottom Cleaner is a heavy duty boat bottom cleaner that instantly removes exhaust, rust and stains caused by algae from fiberglass / gel-coat boat hulls on contact.

This product is much safer and much easier to use than traditional acid based hull and boat bottom cleaners yet works better.

There are no odors or fumes (VOC’s) and will not burn your clothes like the acid cleaners. Strong fumes and ruined clothing are the top two complaints when using acid based hull cleaners. WSI Boat Bottom Cleaner is made with an “acid replacement” which is just like it sounds, a safer version of the acid cleaners.

Performance WSI Boat Bottom Cleaner is every bit as good if not better than the acid cleaners.
