So, inspired by several of Karen's posts at Bakersfield Dressage, here are my 5 barn things:
Sparkly pink crop - used to be my "show" crop, but I've since gained a modicum of traditionalist views...and a gelding! Now it's my schooling whip and I save the black one for shows. Super easy to find if I accidentally leave it out in the ring!
White Vinegar - I use it to clean out feed tub, grain buckets, water buckets, and mixing spoons. I don't dilute it - I just spray it on things full strength, then add water and either scrub or hose off. Its a powerful cleaning and antibacterial agent, yet completely non-toxic of course.
Oster brush - It is one of the mysteries of the universe as to why this brush works so much better than regular hair brushes. It doesn't look especially high-tech, but I swear it brushes through tangles quickly, adds volume, and does not rip hair out!
Hair Moisturizer by Healthy HairCare - Though its name is quite generic, the product is not. I've been spritzing Hemie's body 2 or 3 times a week and generously coating the tail. It works great as a detangler which is helping his tail grow out, but it's also a nice coat conditioner making the hair feel softer and look shinier. You dilute it quite a bit - one part moisturizer to 8 parts water, so this little bottle lasts a while!
A bonus thing is in several of the above photos - pink electrical tape! I have pink electrical tape on pretty much all of my barn stuff. It helps me keep track of stuff that is mine and helps reduce my things going missing.
