cleaning undercarriage

[jpc]

OK How do you guys clean under a car ?? Do you rinse than degrease and
rinse again ?? What do you use ?? I am trying to clean the underside of my
car. I used p21s tac seemed to do a good job. Will have to make it part of
my routine. I noticied that you can get spray on products that leave a shine
on the bottom of the car. Has anybody used them ?? Thanks in advance.
I have been told that I am anal about my car . Well they are right.

Wheel Wells

Periodically remove the wheels (one at a time utilizing a car jack and / or axle stands) to enable cleaning the back of the wheel, callipers and give better access to the wheel wells. Ensure that the vehicle body is secure by placing on axle stands.
?Rinse wheel well thoroughly with water.
?Use a 1:1 solution of P21 Total Auto Wash a d-limonene (citrus) based cleaner and water in a spray bottle, spray the wheel wells and let the solution dwell for 3-5 min
?Agitate and brush the road dirt / grime the wheel well and suspension parts, brake callipers, etc
?Spray the area thoroughly with a high pressure water spray
?Remove any road asphalt with a safe solvent (Stoners Tarminator)
?Repeat if necessary
?Use P21S Polishing Soap on all metal parts (taking care to avoid the brakes)
?Rinse using a high pressure hose / nozzle to remove soap residue
?I recommended wearing rubber gloves, once finished, rinse the wheel wells and dry them with an old terry towel.
?Once they have thoroughly dried spray them with 1z einszett Tiefenpfleger -Vinyl-Rubber Care and Protectant, Adam?s Undercarriage Detailer or Chemical Guys Bare Bones (avoid spraying the brake rotor) which leaves a matt finished look without grease and also provides a protection for the plastic

Undercarriage
After removing dirt, road grime, and etc neutralise the effects of the acidic road salt on the suspension / undercarriage (See also Salt and Road salt)
Methodology
?Thoroughly spray an undiluted citrus cleaner (P2IS Total Auto Wash) and let it soak in; remove by thoroughly rinsing with water. If you have a pressure washer available, fill tank with citrus cleaner and spray undercarriage (do not use excess pressure as water may penetrate crevices and seams where it cannot drain, causing corrosion), let it soak and then remove with plain water
?Spray undercarriage with (POR-15 Marine Clean?) one application will leave no residues, noxious fumes or flammable solvents (Canada-POR15.com)
?Apply two coats (allowing first coat to dry) of a rust inhibitor paint (POR-15 Rust Inhibitor, allow drying between coats.

THANKS for the reply. I used the products you mentioned. P21s tac and the chem.guys bare bones. I also used p21s and chem guys grim reaper on the
bottom of my car. Am planning on using chem guys bare bones on underside

the undercarriage is a pain in the arse to do

Purple Power degreaser works nicely though.
