W4 Citrus Foam is a pH neutral formula that removes hard to shift grime, without damaging sealants, coatings or waxes.

It combines an effective citrus degreaser with a strong foaming agent making it tough on road grime and bug splatter, but kind to waxes and coatings.

It can be used at a dilution of up to 1:400 through a foam lance, or up to 1:25 through a pump sprayer.

Features & Benefits:

  • Removes road grime easily
  • Non-caustic formula
  • 100% biodegradable
  • pH Neutral

Storage and use:

  • Use in conjunction with a snow foam lance
  • Keep out of direct sunlight
  • For light dirt we recommend a 1:400 dilution, and 1:200 for heavier soiling
  • Foam Canon dilution of up to 10:1
  • Allow the foam to dwell on the surface for 5 minutes and then rinse thoroughly
  • W4 can also be used with a pump sprayer at a dilution of 1:20
  • Do not allow the product to dry on the surface

    This product makes cleaning a dirty and grimy car so much easier. It removes bugs and is perfect as a first foam before a contact wash. The product smells good and foams up great!

    Citrus Foam used for traveling

    I bought a pump sprayer and have been using it whilst on a roadtrip. Works amazing.

    Thick sticky foam

    This pre-wash performed great on my first use. Nice thick foam that lifted the dirt from my car. Smells great
