The Fix-It Playbook — How to Clean & Reseal Tile Grout | 5-Page PDF | 2026 Edition

Dingy, stained grout makes a whole bathroom look tired — and unsealed grout drinks up water and grows mold. Cleaning and sealing brings the tile back to life for a few dollars.

Inside: Why grout is the thing that ages a bathroom · The honest cost comparison · Step 1: What sealing actually does · Step 2: Clean it first, the right way · When to stop and call a pro instead · What you'll need · Troubleshooting · What the repair tech won't tell you.

Doing it yourself: grout cleaner and a bottle of sealer run about $15–25, and a brush you may own. Calling a pro: $200–400 to deep-clean and seal a bathroom's grout.

5 pages of labeled diagrams, parts lists and real numbers — no filler, no 40-minute video. Instant PDF download: print it for the garage or follow it on your phone with the parts in hand. Yours to keep, no subscription.
