The short version
- Wipe with a soft cloth, mild dish soap and warm water. Rinse. Dry.
- Never use bleach, chlorine, toilet-bowl or tile cleaners, or anything abrasive.
- A rust spot is surface contamination, not the bar failing. Lift it with a mild cleanser, working with the grain.
- Twice a year: tug the bar hard, and look at the silicone where the flanges meet the wall. If either has changed, call us.
Everyday cleaning
Stainless steel stays clean the same way a good kitchen sink does. Once a week or whenever you clean the shower, wash the bar with a soft cloth or sponge, a little mild dish soap and warm water. Rinse with clean water and dry it with a towel — drying is the step people skip, and it's what prevents water spots and mineral film in DFW's hard water.
For fingerprints or a dull film, a stainless-steel cleaner or polish from the grocery store works well; follow the label and wipe along the grain of a brushed finish. Polished (mirror) bars show marks more readily and reward a quick dry after each shower.
Matte black, white and bronze bars have a powder-coat or plated finish over the steel. Treat them the same way — soap, water, soft cloth — and never use anything abrasive, which can wear through the finish.
What never to use on a grab bar
Chlorides are the enemy of stainless steel. Bleach and chlorine-based cleaners, and acidic bathroom products, break down the thin protective layer that keeps stainless from rusting. Most "rusty grab bar" calls we get trace back to a cleaner, not the bar.
- Bleach or anything "with bleach"
- Toilet-bowl cleaners and lime or scale removers (Lime-A-Way, CLR, Tilex and similar)
- Tile, grout and mildew cleaners with acid or chlorine
- Scouring powders and pads, steel wool, wire brushes — these scratch the surface and steel wool leaves iron particles that rust in place
- Abrasive "soft scrub" creams on powder-coated or plated finishes
If a harsh cleaner does land on the bar — spray drifting from the toilet, say — rinse it off with plenty of water straight away and dry it.
Knurled and peened bars
Textured bars grip better when hands are wet, and the texture can hold a little soap film. A soft nylon brush (an old toothbrush is perfect) with dish soap clears the pattern in a few seconds. Rinse and dry as usual. Nothing harsher is needed. More on the two textures in our knurled grab bar article.
Why a stainless bar can show a rust spot
The 304 stainless steel we install is highly rust-resistant, not rust-proof. It protects itself with an invisible chromium-oxide layer that reforms whenever the surface is clean and has air. Three things interfere with that:
- Chlorides — bleach, chlorine cleaners, and concentrated urine spray around a toilet-side bar.
- Iron contamination — a steel-wool scrub, a steel tool, or iron-rich water leaves particles on the surface that rust and stain the bar underneath them.
- Sitting wet under soap scum or mineral film for weeks, which starves the surface of air.
The result is usually a small tan or orange spot on the surface. It is cosmetic and removable. If it's ignored for a long time it can pit, so it's worth dealing with when you see it.
Removing a rust spot
- Wet a soft cotton cloth and the spot with clean water.
- Put a little mild, non-chloride cleanser on the cloth — Bon Ami or Bar Keepers Friend both work. Not a chlorinated powder.
- Rub gently in the direction of the grain until the spot lifts. For a stubborn spot use a non-metallic scrub pad (never steel wool) with the same cleanser.
- Rinse thoroughly and dry completely.
If a spot comes back in the same place after cleaning, something is still contaminating it — check what's being sprayed nearby. If a bar has real pitting or the finish is lifting, send us a photo; product finish defects are handled under the manufacturer's warranty and we'll help with the claim.
Two checks a season
- The pull test
- Grip the bar and pull hard, straight out from the wall and downward, the way you would in a fall. It should not move, flex or creak. If it does, stop using it and call us. Loosening caused by our workmanship is covered for one year under our installation warranty, and we want to know either way.
- The sealant
- Look at the silicone bead where each flange meets the wall in a shower or tub. It should be intact, with no gaps or peeling. Sealant is what keeps water out of the wall behind the bar. If it's cracked or missing, a bead of mildew-resistant bathroom silicone restores it; we're happy to do this during any visit.
That's the whole job. Mild soap, a dry towel, and two looks a year.
