Reply To: Getting years of crust off

[JOSEPH BRINCAT]

There is basically two kinds of “crud” , The more common stuff is oil/ grease based, this responds to alkaline cleaning agents. The other is mineral based, like lime / hard water stain, this responds to acidic cleaners. A little heat will help both.

Most if what we encounter is oil based… my go procedure for heavy baked on crud is… spray it down with oven cleaner then pressure wash at the car wash.  Don’t let the strong alkaline cleaners linger too long on aluminum and say goodby to paint and decals. Use caution and appropriate PPE.
