To clean a fiberglass shower with vinegar, mix equal parts of white vinegar and water in a spray bottle, apply the solution to the surfaces, let it sit to break down soap scum and mineral deposits, and then wipe and rinse clean. Vinegar is a mild acid that cuts through the alkaline residue left behind by hard water and soap without scratching the delicate resin surface of a fiberglass unit.

Fiberglass requires a gentle touch. Unlike porcelain or ceramic tile, fiberglass can scratch easily, and harsh chemical abrasives will dull its finish over time, making it prone to absorbing even more dirt.

Collect the items you will need for the job. You will need plain white vinegar, liquid dish soap, warm water, a clean spray bottle, a soft-skinned sponge or microfiber cloth, and a dry towel. Avoid steel wool, stiff-bristled brushes, or abrasive scouring pads, as these will permanently scratch and ruin the fiberglass surface. If you are sensitive to the strong aroma of vinegar, ensure the bathroom window is open or the exhaust fan is running to keep the air moving.

Mix the Cleaning Solution

Prepare the primary cleaning spray by combining equal parts white vinegar and warm water inside the spray bottle. Ensure the water is warm rather than boiling, as extreme heat can warp plastic spray bottles or create an overly pungent vapor when mixed with the acid.

For areas with heavy soap scum accumulation or stubborn grime along the lower walls and tub floor, you can enhance the cleaning power by adding a small squirt of liquid dish soap to the vinegar and water mixture. The dish soap acts as a surfactant, helping the liquid cling to vertical walls longer and breaking down oily body oils more effectively. Gently swirl the bottle to combine the ingredients without creating excessive suds.

Apply the Solution and Wait

Generously mist the entire interior of the shower, starting from the top walls and working your way down to the base. Ensure that every surface, including the faucet fixtures, soap dishes, and the floor, is thoroughly dampened by the spray. Pay special attention to corners and crevices where mildew and pink residue tend to accumulate.

Once the surfaces are coated, let the mixture sit undisturbed. Vinegar needs time to chemically react with and dissolve hard water scale and soap film. Depending on how much buildup is present, leaving the solution alone for fifteen to thirty minutes is usually sufficient. Do not allow the vinegar to dry completely onto the fiberglass during this waiting period. If you notice the walls drying out in certain spots, mist them lightly again to keep the active solution working.

For stubborn spots or textured flooring that traps dirt, you can apply a tiny amount of baking soda directly onto your damp sponge to create a very mild, non-scratch paste. Gently rub the paste over the problem areas. The combination of vinegar and baking soda will create a mild fizzing reaction that helps loosen trapped debris, but be sure not to scrub aggressively. Fiberglass is essentially a hardened plastic layer over glass reinforcement, and vigorous scrubbing with abrasive powders will wear away the glossy topcoat.
