CLR!

Dave Yates (PAH)

Be careful out there! CLR can hurt you if you're not careful. reading through the MSDS sheet and a CLR web site today & they said not to put CLR in a spray bottle! Guessing they've never seen a modcon SS HX that's in need of cleaning. Stuff does a great job, but it's tough on the mucus membranes.

Was told the use of a brass gas-grille brush was ok with ss.

Main reason for that is spray carryover. Lime Away comes in a spray bottle, but as its the same composition as CLR (phosphoric acid), should wear a face shield (not just goggles) when spraying it.

If the deposits aren't too bad and time isn't an issue, hot household white vinegar works nicely and is safer to use. Its slower to work than phosphoric or hydrochloric acids. Heat it up, spray it on liberally, let it soak, spray again and scrub. But only if the deposits are fairly light, time isn't an issue and safety is (kids and pets, forgot the PPE, yaddayadda...)
