Cap the spray bottle tightly and shake it gently to blend the water, vinegar, and soap into a uniform solution. Before applying it to the entire shower, it is wise to test the mixture on a small, hidden corner of the fiberglass to ensure the surface tolerates the acid without any adverse reaction, though standard fiberglass generally responds very well to diluted vinegar.

Remove all personal items, bottles, soaps, loofahs, shampoo racks, and bath mats from the stall or tub enclosure. Clearing the area completely ensures you have unobstructed access to every square inch of the fiberglass surfaces, preventing cleaning solutions from contaminating your personal care products and allowing you to work efficiently without awkward maneuvering.

If you have a shower curtain, take it down or pull it completely out of the way. If you have glass doors enclosing the shower, slide them open fully so you can reach the tracks and the edges where the fiberglass meets the frame.

Take a moment to sweep or rinse away any loose hair, dust, or large debris from the shower floor. Rinsing the area beforehand prevents loose dirt from turning into mud when you apply your liquid cleaner, which can make the scrubbing process more difficult and potentially drag abrasive particles across the delicate fiberglass finish.

Apply the Vinegar Mixture

Once the entire shower is thoroughly misted, step away and let the solution sit undisturbed. This resting period is crucial because it allows the acidic properties of the vinegar to penetrate and loosen the hardened soap scum and mineral scale. Depending on how heavy the buildup is, leaving the spray on the surfaces for about fifteen to twenty minutes is usually sufficient. Do not let the vinegar dry completely onto the fiberglass, so keep an eye on the time and reapply a light mist if the room is particularly warm or drafty.

Scrub the Fiberglass Surfaces

Select a non-abrasive scrubbing pad or a soft-bristled brush designed specifically for bathroom surfaces. Avoid steel wool, stiff metal brushes, or coarse scouring powders, as these will permanently scratch, gouge, and ruin the glossy gel-coat finish of the fiberglass.

Starting again from the top and working your way down, gently move the scrubber in circular motions across the walls. The combination of the vinegar breaking down the grime and the mechanical action of the pad will lift the soap scum away from the material. Focus extra attention on corners and textured floor areas where dirt tends to lodge tightly.

If you encounter stubborn spots or ring stains around the base of the shower, apply a little extra spray directly to those specific areas and gently work the pad over them until the residue begins to lift and dissolve into a light foam.

Rinse the Residue Away

Fill a clean bucket with warm water, or use a handheld showerhead if your enclosure is equipped with one. Rinse every surface systematically from the top down, making sure to wash all loosened soap scum, dirt, and residual vinegar down the drain.

Take care to inspect the corners, ledges, and floor edges where soapy water likes to pool and dry. If any vinegar or soap residue is left behind, it can dry into a hazy film, counteracting your cleaning efforts. Rinse until the water running down the drain is completely clear and the surfaces no longer feel slick or soapy to the touch.

Take a clean, dry microfiber cloth or a soft cotton towel and wipe down all the wet fiberglass surfaces. Drying the shower manually prevents water spots and mineral rings from forming as the remaining moisture evaporates.

Using a squeegee on the walls and floor is another efficient way to push excess water toward the drain before following up with a cloth. Once the fiberglass is completely dry, inspect your work under the bathroom lights. The surfaces should look clean, bright, and free of the dull film that was present before you started. You can now return your shampoo bottles, soaps, and mats to their proper places, leaving the shower ready for its next use.
