The Homeowner’s Guide to Caring for Fiberglass and Steel Doors

Fiberglass and steel doors are built to handle busy households and tough weather. With a little routine care, they keep their good looks, seal out drafts, and work smoothly for years. Use this fiberglass door maintenance checklist and steel door care guide to keep your entry looking new with simple, DIY steps.

Start With Routine Cleaning

Dirt, salt, and pollen wear on finishes over time. A quick monthly clean goes a long way.

• Mix a few drops of mild dish soap in warm water.
• Wipe the slab, jamb, and sidelights with a soft microfiber cloth.
• Rinse with clean water and dry to prevent spotting.

How to clean fiberglass doors: skip abrasive pads and harsh solvents. For scuffs, try a non-abrasive plastic-safe cleaner or diluted vinegar, then rinse. Caring for steel entry doors is similar, but dry thoroughly and spot-treat any paint chips right away.

Protect the Finish And Color

Sun and moisture are the two big threats to exterior finishes.

• Fiberglass: if your door is stained, refresh the topcoat every 2 to 3 years or as the manufacturer recommends. For painted fiberglass, touch up nicks promptly.
• Steel: touch up chips with color-matched exterior paint and a rust-inhibiting primer. This simple step helps prevent rust on steel doors.
• Glass: clean with a non-ammonia glass cleaner to protect grilles and finishes.

When in doubt, test new cleaners on a hidden spot first. Stick with best cleaners for fiberglass doors that are pH neutral and non-abrasive.

Keep Hardware And Weatherstripping Healthy

Smooth hardware and tight seals are the secret to comfort and quiet.

• Hinges and locks: once each spring and fall, add a small amount of silicone or Teflon lubricant to moving parts. Wipe away extra to avoid residue.
• Weatherstripping: inspect for cracks or flattened sections. Clean with mild soap and water. Replace pieces that no longer spring back.
• Threshold: vacuum debris from tracks and adjust the sill so the sweep just kisses the threshold.

Seasonal Maintenance Guide For Exterior Doors

A little seasonal attention keeps everything on track.

• Spring: deep clean, check caulk lines, and tighten hinge screws.
• Summer: shade where possible, verify topcoat condition, and confirm the latch engages cleanly as humidity rises.
• Fall: lubricate hardware, replace worn sweeps, and confirm the door seals before the first cold snap.
• Winter: wipe away road salt and condensation and watch for drafts that signal it is time to adjust the strike or weatherstripping.

Spot Issues Early

Catching small problems early pays off.

• Fiberglass: chalky patches, fading, or hairline scratches tell you the topcoat needs attention.
• Steel: bubbling paint or orange specks are early rust signs. Sand lightly, prime with a rust inhibitor, and repaint.
• Operation: if the door drags or the latch sticks, tighten hinge screws and check that the house settling hasn’t shifted the opening.

FAQs

You had questions. Here are the quick hits, in plain language. If we missed yours, tell us and we will add it.

How often should I clean my door?

A light monthly clean is enough for most homes. If your door faces a busy street or the lake breeze, bump it to every two weeks during peak seasons.

Can I pressure wash my door?

Skip the pressure washer. High pressure can force water behind seals. A gentle hand wash is safer for finishes and hardware.

What paint works on steel?

Use an exterior acrylic or alkyd enamel with a rust-inhibiting primer. Sand glossy surfaces lightly before painting.

Do I need to reseal a fiberglass door?

Stained fiberglass doors need a UV-protective clear coat every few years. Painted fiberglass needs touch ups when you see chips or wear.

How do I maintain steel front doors in winter?

Keep them clean and dry, lube the latch, and touch up chips right away to block rust. Check the bottom sweep for a tight seal.
