Some time ago, we received a consultation from Mr. Li who comes from Shenzhen. He said his clients complained to him recently because when they used bottle cleaning brush for hydroflask to wash bottle several times ,they found that the bottom of the bottle was scratched. Mr. Li was very distressed. He did not know what’s problem about the bottle cleaning brush for hydroflask? Mr. Li said he got to know us from a friend’s introduction, he knows we are experts in the production of brushes. So, he hopes us can solve the problem for him.

In order to solve Mr. Li's problem more quickly, we advised him to send us the exact bottle. After receiving the bottle, we cleaned the bottle with different brush heads. It was found that a bottle cleaning brush for hydroflask with a sponge head will not scratch the bottom of the bottle, and has a good water absorption and can clean thoroughly. Later, after having a consultation of the technical department and online search for relevant information, we found the final conclusion is that the sponge on the brush head is the most suitable for this plastic bottle. finally, we sent a bottle cleaning brush for hydroflask with a sponge head to Mr. Li.

7 days later, we received a call from Mr. Li again. He said that the bottle cleaning brush for hydroflask did not scratch the bottom after testing. It also gave his customers a free trial for 4 days. The trial feedback of the customers was very good! Then he ordered 10,000 pieces bottle cleaning brush for hydroflaskes from us!
