Display MoreThe underside of my hood was looking nasty so decided to clean it. Used an old method for cleaning plastic on my ATVs, foaming tire cleaner.
1. Opened the hood and used a tarp to cover the engine and headlights.
2. Spray the entire underside of the hood with Armorall tire foam (use whatever brand you have) and let it work for 10 minutes.
3. Spray with soapy water and touch all the surfaces with a soft brissle brush. I used a pump up garden sprayer with water and dish washing liquid.
4. After brushing spray with soapy water again then rinse with a hose.
5. Blow dry. Several spots will hold a lot of water but a circuiteer or leaf blower will get it all.
I have done a little different a few times. First off understand that I have never used a water hose on my SS, with one exception and that was a pressure washer to get rid of the Georgia clay. Now , understand that under my hood is black and I have seen some that were body color. I cover the engine and the front with a small tarp. Then I spray under the hood with the Lucas tire treatment and let sit overnight, the next morning it looks just like it was brand new. NO SCRUBBING AND NO WATER HOSE Oh! and no hurting back
