J.Racenstein X19 Glass Restorer

Oxalic Acid. One of the milder acidic cleaners. Not as strong as a Hydrochloric or Hydrofluoric Acid, which are found in One Restore and CC550.

X-19 Glass Cleaner & Restorer is recommended for glass surfaces that will not come clean with washing.

X-19 is an acidic blend of wetting agents and detergents specially formulated to restore surfaces.

Additionally, it removes hard water marks, stains caused by run-off from unsealed masonry, airborne pollution and acid rain haze that causes oxidation to glass.
