thebob Posted October 1, 2020 Share A little cautionary tale from my experience this week. I washed my bike, using the same bike wash I have used for ages. Sprayed it on, cleaned the bike off with a brush and water and then rinsed it with the hose. As I was feeling a bit hungry, I went inside for a bit of lunch before drying it. Came back 15 minutes later and started to dry it off. I noticed what appeared to be a water mark on the one fork stanchion where the o-ring was when I was washing it. Turns out it was no water mark and is actually where the cleaner and water had collected around it and eaten a slight groove into the anodising of the stanchion. Upon further investigation I can actually feel an increase in seal drag when the fork moves over this part of the stanchion and so will be ponying up for a new CSU. Luckily the local distributor had one, which is on its way to me. From now on, I'm also only using car shampoo in the bike Link to comment Share on other sites More sharing options...

I do not understand how a non corrosive cleaner / degreaser could have done this... Link to comment Share on other sites More sharing options...

DR ◣◢ Posted October 1, 2020 Share That’s a very very corrosive cleaner that I assume needs to be diluted.  I’ve used Dirt Nurse for years with zero issues when diluted correctly and even concentrated where the bike was really dirty.  I cringe when people use just any cleaners on their bikes.

JBK Posted October 1, 2020 Share Please post brand.I don't think it's right / fair to post the brand name before contacting the supplier first for comment.... Â If it's not a non-corrosive then it shouldn't be used anywhere near a bike anyway. Link to comment Share on other sites More sharing options...

Steven Knoetze (sk27) Posted October 1, 2020 Share I believe any bio-degradable soap or cleaner is safe.Is this an accurate assumption? Link to comment Share on other sites More sharing options...

Furbz Posted October 1, 2020 Share i've been using diluted clean green for years....no issues at all.that said i have never left it on the bike. rather a sponge bath over the frame and parts followed by a proper spray off.never had any issues RobertWhitehead and Schnavel 2 Link to comment Share on other sites More sharing options...
Butterbean Posted October 1, 2020 Share I've stopped using any chemistry on the bike. Honestly, it comes clean with a wet cloth and to be fair, no chemistry helps the wax and grease on drivetrain bits. After having brake pistons get stuck, issues with bearings, etc, nothing with any kind of degreasing action goes near it, even car wash products.  Water on the frame and bits, dry cloth to clean the drivetrain parts, and Ultrasonic for the chain. Any particularly grubby spots get a harder wipe with the cloth and it removes greases and messes. Have had so much less trauma and cleaning is also quicker than when I used to use soap on the bike!

thebob Posted October 1, 2020 Share I do dilute the cleaner, plus minus 50/50. Won't be naming the brand either, but I will be in contact with them to make them aware of what happened. It is marketed specifically as a bike wash, so maybe they need to look at the formulation or maybe I was just unlucky Link to comment Share on other sites More sharing options...

Have been using it to wash my bike all the time and haven't had any issues yet. Thought it was the least caustic of any cleaning solution Link to comment Share on other sites More sharing options...

Everyone used to use it for everything but now there's other products that work just as well if not better, without the corrosive chemicals and are better for the environment... In the original post, he says he did rinse the bike before taking a break and that the damage was done during washing... Personally, I use ecologic, non toxic, non corrosive cleaner / disinfectant / degreaser for my bikes (cars) and drive train (in different concentrations) - my wife now also uses it in place of almost everything else for the house, kitchen, bathrooms, etc. https://stealthhealth.co.za/ecologic/ Link to comment Share on other sites More sharing options...
