That means you wear gloves. I didn't but I never wear gloves no matter what chemicals I'm working with, I. Don't really care because my hands are so tough, nothing bothers them.... This stuff turned my alligator bulletproof skin into baby skin In one panel. Which is great because the wife is always complaining About the the escalator and elevator grease I get under my fingers and in the dry cracks From work, this cleaned it all out. Number two, this is not good to use on very, very old thin trailer paint. My trailer is 7 years old and has never been washed. The paint is aged and has years of acid rain chewing into it. Many years or minerals and deposits from rain and trees that has been building on it. I could see where this was starting to eat through the paint so I worked in very small areas and worked very fast. If you're careful even with thin old worn paint, it will still do its job without damaging. You just have to be within seconds of being correct on when to scrub, apply and rinse... Very, very small margin of error so if you're not really good, don't do it.. If you let it get on aluminum like fenders, it will etch into them. And then you will be polishing them later. This stuff and aluminum don't go well together. But all in all this stuff is strong. And that's what I wanted. So it is perfect for what I need. And you can see by my pictures it does a pretty good job. Use it full strength and work fast and small areas.. I don't care how tough your skin is wear gloves! If you're a mechanic, do one panel without gloves, it will make your skin look great and soft and your wife will love it No more complaining on how grungy your, your hands look anymore. Review: Best Black Streak cleaner - First of all we've owned an weekend warrior 5th wheel toybox trailer for 23 years. Yes it has its blemishes but I've kept it CLEAN. It sits outside all year in storage yard. A good power washing usually does the trick but the silicone & lap sealer is now dark & deposits black streaks at bottom of windows & rain gutter lip. I also have discoloration at the awning arms. That being said I've used MANY self proclaimed black streak sprays & cleaners all have disappointed. This cleaner works great & surpassed my expectations. Im pretty meticulous & i dont write reviews on most products. This can be placed in a spray bottle at full strength & wiped on to remove discolorations. Use as directed & wash off with water. It cleans off road grime & diesel exhaust really well. I did not have any issues with the old paint & oxidation. It cleaned spots off of plastic storage doors, entry doors hatches, gas doors & Black Wheelscuffs off interior walls. Use an old towel w texture for rubbing & removing streaks. I highly recommend! ## Features - Allows you to remove those black streaks and stains from boats, trailers and RVs with ease - Just spray it on and wipe it off, it's that simple - A multi-purpose cleaner/degreaser designed to remove soils and marks with a minimum effort on a wide variety of hard surfaces - Leaves surfaces streak-free and sparkling clean - No rinsing needed and residue free - DIRECTIONS: To remove black streaks from RV, trailer or boats spray product onto a dry, clean cloth or towel wipe surface clean.

Then wash with Super Suds and rinse from the top down. - Note: Not recommended for use on old surfaces that have not been maintained; paint removal may occur. Use dedicated brush & bucket for each product used. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007H2RJ80 | | Best Sellers Rank | #75,591 in Automotive ( See Top 100 in Automotive ) #40 in RV Cleaners | | Brand | Biokleen | | Customer Reviews | 4.3 4.3 out of 5 stars (1,081) | | Date First Available | March 5, 2012 | | Is Discontinued By Manufacturer | No | | Item Weight | 8.4 pounds | | Item model number | 1220.1588 | | Manufacturer | Bio-Kleen | | Manufacturer Part Number | M00509 | | Model | M00509 | | Product Dimensions | 5 x 5 x 11 inches | | Special Features | Residue Free, Streak Free ♬ | ## Images ![M00509 Black Streak Remover - 1 Gallon., 128 Fl Oz (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/61pXGDO2BeL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's strong stuff! *by A***I on August 2, 2023* This stuff works great!
