Cleaners That Don't Ruin Black Engine Paint?

[dazco]

I often used simple green which i had used in the past to soak my greasy engine then hose off. I had no issues on some bikes but on the triumph it etched the engine paint giving it a mottled look with grayish spots that nothing would remove. So i have a lot of dirt/grease i need to clean in between the throttle bodies thats impossible to get to manually and i want to soak it with something like gunk then hose off but i'm not sure if gunk will harm the paint. Does anyone know if it will and if so, do u know of another product i can spray on and let sit then spray off?

LOC (Liquid Organic Cleaner) from Amway/Quixtar is good for grease.

I once used Simple Green on my aircraft engine to remove the built up grime which had formed a layer of crust over the years and yep, it took off the grease allright and the black paint right down to the metal. Seems that varying the strength of the water to solution ratio can dial in different results. I had figured the more the better. NOT. I finally found a liquid called The "Grime" Reaper which almost instantly removed even years of metamorphosised underbelly grease, burned on engine smuck and didn't touch the paint. Completely dissolved that coating and left the paint actually shiny as new. When I wash my bike I use a solution that a BMW rider with 100,000 miles on his new looking machine told me about. Home brew. 1/3 solution each of Liquid Tide, ammonia, and vinegar with that combo mixed 1/3 to 2/3rd of water. Spray on whip/wash off. After years of trying all kinds of solutions that didn't quite do it, this worked really well and kept the bike looking new. On my airplane, the bugs on all the leading edges and the windshield were really stubborn to remove. With this liquid combo, spray on and wipe off immediately and completely. Between the two it's easy to keep my bike looking "showroom".

What do you fly? I sure miss it but lost my medical due to hearing loss. Seems I could have a recreational license but not a Commercial. I have not flown in a decade. Oh well, it sure gives me more motorcycle money...LOL

Just turned 70 but keep my instructor certificate current. I'm instructing in Piper PA28-180's, Cessna 172N,B and E's and Experimental RV-9's as well as Flight reviews in just about anything single engine. I never got my multiengine rating. I'm retired and fly part time. Demand is so great at the moment I could fly full time if I wanted but being retired I split my time between multiple passions: Scuba diving(mostly in the Caribbean), my Bonneville, and Music. I've been a musician for 55 of my 70 yrs and play guitar and harmonica. Lately though I've been trying to learn to really read music and practice time is almost making me into an acetic monk! It's a lot like flying in that the skills atrophy quickly without constant upkeep. Hopefully the old bod will last at least another decade at a level allowing me to continue burning my candle at both ends and the middle!
