Just looking for people opinions on what in bay presoak they find to do the best job cleaning wise (especially with bugs), I currently use Trans-Mates in bay presoak but I'm looking more for cleaning over smell and color.
Parker,over the last 10 years or so I've tried over 20 different products as a presoak.I have found in my area a diluted tire cleaner works best, 24 to 1. The county uses mag cloride on our dirt roads for dust, cdot, for winter ice. I will try Arcadian Services Aurora wc 500 next, @ 120 to 1. stronger if needed.I use their ps-420 for my foam brush. And no, I do Not work for them, but their products work for me. Best Regards! P. S. I us my foam brush on bugs!
I mix two different presoaks, one that has great show and fragrance and one that cleans well. We don't have a lot of problems with bugs, but it melts away bird poop really well. I use the same presoak mix on the auto and in the self-serve.
Hot presoak would do more for bugs than a "better" presoak. You might even consider adding a bug remover option.
