OXALIC Acid 99.6% 10 Lb. Deck, Crystals, Metal Cleaning- Rust Removal, Wood Stain Remover and More!

Great product, worked really well to neutralize sodium hydroxide after chemically stripping cedar.

(Photo before/after)Truthfully I was skeptical when I ordered. My hopes were that it clean sidewalks enough to get HOA off my back. I thought if it would eliminate part of rust and I could pressure wash clean enough to pass inspection I would be happy happy camper!! When I sprayed solution on 1st rusty area, the rust stain started disappearing. I couldn’t believe it!! I did pressure wash after using but there wasn’t any rust to try and clean. It was only normal sidewalk dirt that was being cleaned. This truly is a great product - I would encourage friends, family - anyone who has rust on their sidewalk, drive or any other concrete areas with rust stains. Instructions call for 1 cup to warm water - I didn’t use warm water 😟 and probably used a little more than a cup (not on purpose - just too lazy to be exact). The sidewalk I was using this on was approximately 50-60 feet long and I used 3+ cups of rust oxalic acid. I used a sprayer to apply to sidewalk.

As the title states, I purchased this acid as a treatment for my honeybees. This isnt the common use for most people, but it effective in other ways. If there's are any other beekeepers looking for a cheaper product, this may work for you also. You can use it in treatment pads or turn into vapor for early spring or late season treatment. No matter how you use this, especially, if you're using this in a vaporizer make sure you wear safety equipment! Gloves, mask (with proper filters) and eye protection should be used! Don't allow your pride cause you serious injury because of an accident or ignorance.

Wow! Our irrigation is off of our well and we get rust stains horribly. We bought this house 3 years ago and never cleaned the sidewalk until now and boy, was I blown away. I bought a sprayer from Lowe’s and mixed 1 cup per 1 gallon and applied.

Great Product but it take too long to

I have 50-100 hive depending on my emphasis each year (queen production versus honey production), but I go through lots of Oxalic Acid making the Oxalic Acud/Glycerin Swedish Dishtowel Sponges of the Aluen CAP method, tested, enhanced, and made of note by Randy Oliver’s Scientificbeekeeping.com website. Each 6x7” Swedish Dishtowel Sponge gets 50 grams of Oxalic (by weight) dissolved in 50 grams of Vegetable Glycerin, heated to around 155 degrees F to fully dissolve in the Glycerin - it should be crystal clear like water, not milky or hazing indicating that the Oxaliccis not yet into solution. This is my primary Varroa mite control for most of each bee year!

I have a concrete driveway and sidewalk bordered by lawns. No matter how much I power washed, the yellowish tint never came off. I tried this product and it was like magic. I simply used a watering can to sprinkle the solution on the concrete, and used a broom to swish it around to make sure all the areas were covered. That was it. When it dried, my driveway looked like fresh poured concrete. The yellow tint, cause by the iron in the fertilized, was complete removed. I apply this product twice a year, right after the driveway is power washed to remove dirt, etc.. In a few areas of a particular dark stain, such as where the water runs into the gutter, I applied a second application; that's all it took to remove. True Value sells the same product called Snow Cap, but it is in such small boxes it would cost a fortune to do a driveway. This 'bag' on Amazon is cheap compared to what you would buy locally, and one bag does my 3 car driveway and sidewalk. Been using for years.

Works Great Nice Resealable Package
