303 Products — Make Your Cover Outlast the Sun

Hot tub covers rarely wear out from the inside — the sun kills them. 303 Aerospace Protectant® puts a UV barrier on vinyl covers, headrest pillows, and cabinet surfaces that keeps them from fading, hardening, and cracking. 303 Multi-Surface Cleaner preps the surface without the harsh solvents that strip vinyl, and 303 Mold & Mildew Cleaner clears the growth that takes hold on damp cover undersides. A replacement cover runs hundreds of dollars; a season of 303 costs a fraction of that.

Clean the cover first, then apply about once a month during the season — more often in strong sun. Regular treatment is the single best way to stretch a vinyl cover’s life.

Yes — wipe it on the cover and cabinet surfaces, not into the water. Apply with a cloth rather than overspraying, and any incidental contact won’t harm your water chemistry.
